LOCAL_DISK 读取分配了临时内存缓冲区，有 `gc_ttl_ms`（默认 5000ms）租约。如果客户端超时未完成传输，远端 GC 线程会回收缓冲区，数据丢失。客户端必须在传输完成后主动调用 `release_offload_buffer` 释放，加速缓冲区回收。这种跨节点的缓冲区生命周期管理超出了 `TransferSubmitter` 的职责范围。 + +--- + +### 深度解析3：LOCAL_DISK 的读取速度比 DISK 快吗？ + +**通常 LOCAL_DISK 更快**，原因如下： + +**1. 传输路径对比** + +| 阶段 | DISK | LOCAL_DISK | +|------|------|------------| +| 数据位置 | 本机共享文件系统 | 远端 Worker SSD | +| 读取方式 | 本地文件 I/O（preadv/io_uring） | 远端 SSD → 远端内存 → RDMA → 本地 | +| 目标内存 | 只能写 CPU 内存 | 可直接写 GPU 内存 | +| 网络开销 | 无 | 有（RPC + RDMA） | + +**2. 为什么 LOCAL_DISK 通常更快？** + +- **SSD 性能优势**：LOCAL_DISK 存储在 Worker 节点的本地 NVMe SSD 上，随机读写性能远高于 DISK 使用的共享文件系统（可能是 NFS、CephFS 等网络文件系统，或普通 HDD） +- **并行读取**：LOCAL_DISK 的远端 Worker 使用专用线程池并行从 SSD 读取（`coro_io::post`），然后通过 RDMA 高速传输回来；DISK 的本地文件 I/O 虽然也用 `FilereadWorkerPool`（10线程），但受限于共享文件系统的 I/O 能力 +- **GPU 直写**：LOCAL_DISK 通过 RDMA 传输可以直接写入 GPU 内存（用户通过 `register_buffer` 预注册），而 DISK 的本地文件 I/O 只能写 CPU 内存，如果目标是 GPU 内存还需要额外的 D2H 中转 +- **io_uring 优化**：LOCAL_DISK 的远端 Worker 读取 SSD 时可以使用 io_uring + O_DIRECT 零拷贝读取，避免内核态拷贝 + +**3. 什么情况下 DISK 可能更快？** + +- 数据量很小（网络开销占比大） +- 本地共享文件系统使用 NVMe SSD 且网络带宽有限 +- RDMA 网络不可用，回退到 TCP 传输 + +**4. 速度排序总结** + +```

的优先级：**本地 MEMORY > 远端 MEMORY > LOCAL_DISK > DISK** + +LOCAL_DISK 优先于 DISK 的原因： + +**1. 数据来源的可靠性不同** + +| 维度 | DISK | LOCAL_DISK | +|------|------|------------| +| 数据位置 | Master 管理的共享文件系统路径（`file_path`） | Worker 节点的本地 SSD | +| 创建者 | Master 在 PutStart 时自动创建 | Worker 完成数据卸载后通知 Master 创建 | +| 归属关系 | 无 client_id，全局共享 | 绑定到特定 client_id + transport_endpoint | +| 生命周期 | 随对象存在 | 绑定到客户端，客户端失活时被清理 | + +LOCAL_DISK 的数据由活跃 Worker 写入并管理，数据新鲜且确定可用；而 DISK 是 Master 侧共享文件系统上的数据，可能存在路径解析、文件系统可用性等额外风险。 + +**2. 传输路径的灵活性不同** + +- **LOCAL_DISK**：RPC + RDMA 传输路径，数据可以直接写入 GPU 内存（用户通过 `register_buffer` 预注册） +- **DISK**：本地文件 I/O（`FilereadWorkerPool`），只能写 CPU 可寻址的内存，如果分配器返回了 GPU 内存则读取会失败，需要额外的临时 CPU 缓冲区中转 + +**3. 架构定位不同** + +LOCAL_DISK 是较新的架构设计——当内存不足时，Worker 将 MEMORY 副本卸载（offload）到本地 SSD，形成 MEMORY → LOCAL_DISK 的降级路径。这是数据生命周期中的自然降级，数据仍然由活跃 Worker 管理。而 DISK 是更早期的、由 Master 直接管理的共享存储机制，属于完全不同的存储层。 + +**4. transport_endpoint 的含义差异** + +| 副本类型 | transport_endpoint 含义 | +|---------|----------------------| +| MEMORY | 内存段所在节点的传输引擎端点（RDMA NIC 地址） | +| DISK | 无 transport_endpoint（DiskDescriptor 中没有此字段） | +| LOCAL_DISK | 拥有该 SSD 数据的 Worker 节点的 **RPC 服务地址** | + +LOCAL_DISK 有明确的 `transport_endpoint`（Worker 的 RPC 地址），客户端可以直接发起远程读取；而 DISK 没有远程端点，只能本地文件 I/O。 + +--- + +### 深度解析5：为什么使用了 Hot Cache 就要释放？ + +在 `Client::Get` 和 `Client::BatchGet` 中，如果使用了 Hot Cache（`cache_used=true`），在数据传输完成后必须调用 `ReleaseHotKey(key)`。这不是"释放缓存数据"，而是**释放对缓存块的引用计数**。 + +**Hot Cache 的引用计数机制：** + +``` +GetHotKey(key) → ref_count++ （获取引用，保护缓存块不被驱逐） + ↓ +数据传输/memcpy → 从 blk->addr 读取数据到用户 buffer + ↓ +ReleaseHotKey(key) → ref_count-- （释放引用，允许缓存块重新可被驱逐） +``` + +**`GetHotKey` 做了什么？**（local_hot_cache.cpp L115） + +1. 在 `key_to_lru_it_` 中查找 key +2. 找到后 `ref_count++`（原子操作）——这相当于对缓存块加了一把"读锁" +3. `accessed = true`（延迟 LRU touch 标志） +4. 返回 `HotMemBlock*` 指针 + +**`RedirectToHotCache` 做了什么？**（client_service.cpp L1212） + +1. 调用 `GetHotKey(key)` 获取缓存块（`ref_count++`） +2. 将 replica 的 `buffer_address_` 改为缓存块的内存地址 `blk->addr` +3. 将 `transport_endpoint_` 改为本地地址（变为本地 memcpy 传输） + +**`ReleaseHotKey` 做了什么？**（local_hot_cache.cpp L136） + +1. 在 `key_to_lru_it_` 中查找 key +2. `ref_count--`（原子操作） + +**如果不释放会怎样？** + +`ref_count` 永远不为 0，该缓存块在 `GetFreeBlock()` 中会被跳过，永远无法被驱逐和重用。随着时间推移，越来越多的块被"锁死"，可用缓存容量持续减少，最终导致 Hot Cache 完全失效——`GetFreeBlock()` 返回 `nullptr`，新数据无法进入缓存。 + +**为什么不在传输前就释放？** + +因为 `RedirectToHotCache` 将传输目标重定向到了缓存块的内存地址。如果提前释放引用，缓存块可能被其他线程驱逐（`GetFreeBlock` 会驱逐 `ref_count == 0` 的块），其内存可能被新数据覆盖，导致当前传输读到脏数据。必须在 `future.get()` 确认传输完成后才能释放——此时 memcpy 已经完成，数据已经安全拷贝到用户 buffer 中。 + +--- + +## 第三部分：Put vs Get 对比 + +| 维度 | Put | Get | +|------|-----|-----| +| Master 交互 | PutStart → PutEnd/PutRevoke | Query → 无需再通知 Master | +|

端开关 + +配置文件：`mooncake-store/include/master_config.h`，可通过 `master.yaml` 或命令行参数设置。 + +#### `enable_offload`（默认 false） + +- **false**：SSD offload 完全禁用。客户端调用 `OffloadObjectHeartbeat(enable_offloading=false)` 时，Master 清空该客户端的 offload 队列并释放所有 refcnt。对象只有 MEMORY 副本，内存不足时直接 eviction 丢弃。 +- **true**：启用 offload。客户端 `FileStorage` 初始化时注册 LOCAL_DISK segment（`MountLocalDiskSegment`），心跳线程开始工作。PutEnd 或 eviction 时对象可被加入 offload 队列。 + +#### `offload_on_evict`（默认 false） + +- **false（模式 A）**：PutEnd 完成后**立即**将该对象的所有 MEMORY 副本加入 offload 队列。意味着所有写入的数据都会尽快下沉到 SSD，内存中的副本仅作为 RDMA 访问源存在，直到 offload 完成后由 Master 释放。 +- **true（模式 B/C）**：PutEnd 时不做任何 offload 操作。只有当内存使用率超过 `eviction_high_watermark_ratio` 触发 `BatchEvict` 时，才将候选淘汰对象入 offload 队列。**区别**：模式下 B 对象在内存充裕时不会被 offload，仅在被选中淘汰时才持久化到 SSD。 + +#### `offload_force_evict`（默认 false） + +- **false**：在 `offload_on_evict=true` 模式下，如果 offload 队列已满（达到 `offloading_queue_limit_ * kOffloadCapRatio` = 25000），超出上限的候选对象**跳过淘汰**，数据保留在内存中。这会导致本轮 eviction 无法释放足够内存，Master 会打印 WARNING。 +- **true**：在 `offload_on_evict=true` 模式下，offload 队列满时不再跳过，而是**强制 eviction 丢弃数据**。适用于宁可丢失数据也要保证内存可用的场景。 +- **注意**：此开关仅在 `offload_on_evict=true` 时生效。单独设置（模式 D）无任何效果。 + +#### `promotion_on_hit`（默认 false） + +- **false**：LOCAL_DISK 副本被 Get 命中后，后续访问始终走 SSD Load 路径（读磁盘 → staging buffer → RDMA 传输）。 +- **true**：Get 命中 LOCAL_DISK 副本时，`TryPushPromotionQueue()` 被调用，通过 Count-Min Sketch 统计访问频率。频率达到 `promotion_admission_threshold` 的 key 被加入 promotion 队列，心跳线程将其从 SSD 提升回 MEMORY 副本。**效果**：热点数据自动回到内存，后续访问走 RDMA 零拷贝路径，避免 SSD I/O 延迟。 + +#### `promotion_admission_threshold`（默认 2） + +- Count-Min Sketch 的频率阈值。key 被访问的次数（近似）达到此值才有资格 promotion。 +- **设为 1**：任何被访问一次的 LOCAL_DISK key 立即被加入 promotion 队列。适合缓存空间充裕的场景。 +- **设为更大值（如 5）**：需要多次访问才 promotion。避免一次性访问冷数据占用 promotion 资源。 + +#### `promotion_queue_limit`（默认 50000） + +- 全局（所有 shard 共享）的待 promotion 任务上限。 +- **达到上限**：`TryPushPromotionQueue` 中的容量门控拒绝新任务，热 key 暂时留在 SSD。 +- 此上限同时控制 `promotion_in_flight_` 计数器，防止 promotion 占用过多内存。 + +#### `eviction_high_watermark_ratio`（默认 0.85） + +- 内存使用率触发 eviction 的阈值。 +- **设高（如 0.95）**：容忍更高的内存使用率，eviction 触发更晚，留给 offload 的时间窗口更短。 +- **设低（如 0.70）**：更早触发 eviction，内存更充裕，但在 `offload_on_evict=true` 模式下会提前开始 offload。 + +#### `eviction_ratio`（默认 0.05） + +- 每轮 `BatchEvict` 的目标回收比例（相对于总内存）。 +- **设大（如 0.10）**：每轮淘汰更多对象，eviction 频率更低但每轮耗时更长。 +- **设小（如 0.02）**：每轮淘汰少量对象，更平滑但 eviction 线程更频繁工作。 + +### 8.2 Client 端环境变量 + +#### `MOONCAKE_OFFLOAD_FILE_STORAGE_PATH`（默认 `/data/file_storage`） + +- SSD 上的存储目录路径。BucketStorageBackend 在此目录下创建 `.bucket` 和 `.meta` 文件。 +- **不设置**：使用默认路径，需确保该目录存在且有写入权限。 +- **建议**：设置为 NVMe SSD 挂载点，如 `/nvme/mooncake_offload`。 + +#### `MOONCAKE_OFFLOAD_STORAGE_BACKEND_DESCRIPTOR`（默认 `bucket_storage_backend`） + +- `bucket_storage_backend`：默认推荐。多对象合入桶文件（256MB/桶，500 key/桶），支持 FIFO/LRU 淘汰，支持重启恢复。 +- `file_per_key_storage_backend`：每个对象一个文件。适合调试，大规模场景下文件数爆炸。 +- `offset_allocator_storage_backend`：单文件 + 偏移分配器，1024 分片元数据。高并发性能好，但**不支持重启恢复**（启动时 truncates）。 + +#### `MOONCAKE_OFFLOAD_LOCAL_BUFFER_SIZE_BYTES`（默认 1280MB） + +- Load 路径的 staging buffer 大小。从 SSD 读取数据时先写入此 buffer，再通过 RDMA 传输。 +- **设小**：并发 Load 能力受限，大对象可能需要排队等待 buffer 槽位。 +- **设大**：支持更多并发 Load，但占用更多 Host 内存。 +- 此 buffer 会被注册到 Transfer Engine 用于 RDMA 访问。 + +#### `MOONCAKE_OFFLOAD_TOTAL_SIZE_LIMIT_BYTES`（默认 2TB） + +- SSD 磁盘使用上限。达到上限后 BucketStorageBackend 触发淘汰（如有 eviction policy）。 +- **设为 0**：BucketBackend 默认使用磁盘物理容量的 90%。 + +#### `MOONCAKE_OFFLOAD_HEARTBEAT_INTERVAL_SECONDS`（默认 10） + +- 客户端心跳线程的间隔。每次心跳执行：(1) 拉取 offload 任务 (2) 执行 OffloadObjects (3) 执行 ProcessPromotionTasks。 +- **设小（如 3）**：offload/promotion 响应更快，但 Master RPC 压力增大。 +- **设大（如 30）**：减少 RPC 开销，但数据在内存中停留更久，promotion 延迟更高。 + +#### `MOONCAKE_OFFLOAD_USE_URING`（默认 false） + +- **false**：使用标准 POSIX I/O（pread/pwrite）。 +- **true**：使用 Linux io_uring 异步 I/O。每个线程拥有独立的 io_uring ring（无锁），ClientBuffer 注册为 fixed buffer 避免 mmap 开销，配合 O_DIRECT 绕过页缓存。**仅 Linux 可用**。 + +### 8.3 内部硬编码常量 | 常量 | 值 | 说明 | |------|----|------| -|

MEMORY：数据在内存副本中，可以通过 Transfer Engine / 本地 memcpy 直接读到用户 buffer。 + - DISK：数据在当前节点本地文件中，文件 I/O 写入 GPU buffer 不安全或不可用，所以通常需要 CPU 临时 buffer。 + - LOCAL_DISK：数据在远端节点 SSD 中，当前节点不能直接读这个文件，只能让远端节点 offload 读取，再通过网络传回来。 + +1. **容量/范围检查** + -

MEMORY 路径支持源 offset，可以直接从 `src_offset` 开始读。 + - DISK 路径当前依赖 `allocateSlices` / `Client::Get` 的完整对象切片模型，不能只为任意范围构造完整正确的文件读请求，所以先读完整对象到临时 buffer，再 scatter 目标范围。 + - LOCAL_DISK offload 当前也是从远端 offset 0 顺序读取，不能直接告诉远端“只读 src_offset 之后这一段”，所以读 `[0, src_offset + size)` 到临时 buffer，再取目标范围。 + +3. **完整对象读取：`src_offset == 0 && size == total_size`** + + **[分支A] LOCAL_DISK 副本**： + -

**为什么可以直接写用户 buffer**：MEMORY 副本由 Transfer Engine / memcpy 传输，目标地址可以是已注册的用户 buffer，适合零拷贝读。 + - **怎么读**： + - `allocateSlices(slices, replica, buffer + dst_offset)` + - `FilterQueryResult(query_result, replica)`，确保 `Client::Get` 只看到选中的副本 + -

**为什么不能直接读目标范围**：当前 offload RPC 的对象描述只有目标 slices，没有表达“从远端文件 src_offset 开始读”的接口语义；远端按对象起点顺序读取。 + - **为什么临时 buffer 大小是 `src_offset + size`**：只需要读到目标范围的结尾即可，不必读完整对象。比如要读 `[100, 120)`，远端读 `[0, 120)`，本地再取后 20 字节。 + -

-以下提供两种异步改造方案。 - -### 9.1 方案 1：替换为 spdlog 异步模式 - -使用 spdlog 的 `async_logger`，内部基于无锁环形队列，写日志只做一次 `memcpy` 到队列，后台线程负责刷盘。 - -**改造步骤：** - -1. **CMake 引入依赖** - -在 `mooncake-store/CMakeLists.txt` 中： -```cmake -FetchContent_Declare( - spdlog - GIT_REPOSITORY https://github.com/gabime/spdlog.git - GIT_TAG v1.x -) -FetchContent_MakeAvailable(spdlog) -target_link_libraries(mooncake_store PUBLIC spdlog::spdlog) -``` - -2. **创建全局 async logger** - -新增 `mooncake-store/src/async_logger.h`： -```cpp -#pragma once -#include -#include -#include - -inline std::shared_ptr get_mc_logger() { - static auto logger = [] { - auto dir = std::getenv("MC_LOG_DIR"); - std::vector sinks; - sinks.push_back(std::make_shared()); - if (dir && *dir) { - sinks.push_back(std::make_shared( - std::string(dir) + "/mooncake.log")); - } - auto logger = std::make_shared( - "mooncake", sinks.begin(), sinks.end(), - spdlog::thread_pool(), spdlog::async_overflow_policy::block); - spdlog::register_logger(logger); - return logger; - }(); - return logger; -} -``` - -3. **替换 LOG 宏** - -在源文件中： -```cpp -// 之前 -LOG(INFO) << "get_breakdown key[" << key << "]"; -// 之后 -get_mc_logger()->info("get_breakdown key[{}]", key); -``` - -**优点：** -- 成熟方案，性能好，零分配（fmt 编译期格式化） -- 内置日志文件滚动、多 sink 支持 -- 日志顺序由队列保证 - -**缺点：** -- 引入第三方依赖 -- 需要改所有 LOG 调用点（store_py.cpp、real_client.cpp、client_service.cpp） -- glog 的 `VLOG(1)` 需要单独处理 - -### 9.2 方案 2：在 glog 上包装异步队列 - -不替换 glog，在其上层加一个线程安全队列，LOG 宏改为写入队列，后台线程消费并调用 glog 输出。 - -**改造步骤：** - -1. **定义异步日志队列** - -新增 `mooncake-store/src/async_log_queue.h`： -```cpp -#pragma once -#include -#include -#include -#include -#include -#include - -class AsyncLogQueue { -public: - static AsyncLogQueue& Instance() { - static AsyncLogQueue q; - return q; - } - - void Push(int severity, const std::string& msg) { - { - std::lock_guard lock(mutex_); - queue_.emplace(severity, msg); - } - cv_.notify_one(); - } - -private: - AsyncLogQueue() { - thread_ = std::thread([this] { DrainLoop(); }); - } - - void DrainLoop() { - while (running_) { - std::unique_lock lock(mutex_); - cv_.wait(lock, [this] { return !queue_.empty() || !running_; }); - while (!queue_.empty()) { - auto [sev, msg] = std::move(queue_.front()); - queue_.pop(); - lock.unlock(); - google::LogMessage(__FILE__, __LINE__, sev).stream() << msg; - lock.lock(); - } - } - } - - struct Entry { int severity; std::string message; }; - std::queue queue_; - std::mutex mutex_; - std::condition_variable cv_; - std::thread thread_; - bool running_ = true; -}; -``` - -2. **封装宏替换** - -```cpp -#define MC_LOG(severity) \ - [&]() -> AsyncLogQueue& { \ - if (severity < FLAGS_minloglevel) { \ - static AsyncLogQueue* dummy = nullptr; \ - return *dummy; // 不执行 \ - } \ - return AsyncLogQueue::Instance(); \ - }().Push(google::severity, \ - [](std::ostream& os) { os << - -// 替换使用： -// MC_LOG(INFO) << "get_breakdown key[" << key << "]"; -``` - -3. **逐文件替换** - -将 `LOG(INFO)` → `MC_LOG(INFO)`，`LOG(WARNING)` → `MC_LOG(WARNING)`，`LOG(ERROR)` → `MC_LOG(ERROR)`。 - -**优点：** -- 不引入新依赖，保持 glog -- 改动范围小，只改宏名 -- 日志格式与之前一致 - -**缺点：** -- 日志顺序可能因多线程队列而乱序 -- 进程崩溃时队列中未刷出的日志会丢失 -- 需要处理 glog 的 `LogMessage` API 兼容性 - -###

+``` + +这表示对端后续第一次向本节点某个 UB device 传输时，可以通过 RPC 调用本节点的 `onSetupConnections()`，完成 Jetty 绑定。 + +### 2.8 更新元数据 + +最后： + +```cpp +metadata_->updateLocalSegmentDesc(); +``` + +把本节点的 `SegmentDesc` 发布到元数据服务中。对端通过 `openSegment()` 或 `getSegmentDescByName()` 能拿到它。 + +## 3. 内存注册流程 + +用户调用： + +```cpp +engine.registerLocalMemory(addr, length, location); +``` + +调用链： + +```text +TransferEngine::registerLocalMemory() + -> TransferEngineImpl::registerLocalMemory() + -> MultiTransport 中每个已安装 transport 注册 + -> UbTransport::registerLocalMemory() + -> 每个 UrmaContext::registerMemoryRegion() + -> 每个 UrmaContext::buildLocalBufferDesc() + -> metadata_->addLocalMemoryBuffer() +``` + +### 3.1 在每个 URMA 设备上注册 segment + +`UbTransport::registerLocalMemory()` 遍历所有 `context_list_`： + +```cpp +for (auto& context : context_list_) { + context->registerMemoryRegion((uint64_t)addr, length); + context->buildLocalBufferDesc((uint64_t)addr, buffer_desc); +} +``` + +也就是说，同一块用户内存会在每个可用 UB device 上注册一次。原因是后续 `selectDevice()` 可能选择任意一个 device；每个 device 都需要自己的可访问 segment handle。 + +`UrmaContext::registerMemoryRegion()` 主要做： + +```text +1. 构造 urma_reg_seg_flag_t + - token_policy = URMA_TOKEN_NONE + - cacheable = URMA_NON_CACHEABLE + - access = READ | WRITE | ATOMIC + +2. 构造 urma_seg_cfg_t + - va = 用户虚拟地址 + - len = 注册长度 + - token_value = urma_token + +3. 调用 urma_register_seg() + +4. 保存返回的 urma_target_seg_t* + - local_tseg_list_ + - seg_region_list_ +``` + +`seg_region_list_` 用于根据地址反查本地 tseg；`local_tseg_list_` 用于根据 metadata 中的 index 快速取出本地 segment。 + +### 3.2 构建 BufferDesc + +注册完以后，`UrmaContext::buildLocalBufferDesc()` 会把 URMA segment 序列化： + +```cpp +auto str = serializeBinaryData(&seg(addr)->seg, sizeof(urma_seg_t)); +buffer_desc.tseg.push_back(str); +buffer_desc.l_seg_index.push_back(index); +``` + +`BufferDesc` 中和 URMA 相关的关键字段是： + +```text +addr 本地 buffer 起始地址 +length buffer 长度 +name 内存位置，例如 cpu:0 / * / cuda:0 +tseg[] 每个 device 对应的序列化 urma_seg_t +l_seg_index[] 每个 device 对应的本地 tseg 索引 +``` + +### 3.3 自动识别内存位置 + +如果用户传入的 location 是 `"*"`： + +```cpp +getMemoryLocation(addr, length, only_first_page = true) +``` + +Mooncake 会尝试识别这块内存属于哪个 NUMA node 或设备，然后写入 `buffer_desc.name`。后续设备选择会优先使用与这个 location 更近的 UB device。 + +如果用户显式传入 `cpu:0`、`cpu:1` 等 location，则直接使用用户传入的值。 + +### 3.4 更新元数据 + +最后： + +```cpp +metadata_->addLocalMemoryBuffer(buffer_desc, update_metadata); +``` + +这样远端才能通过元数据拿到： + +```text +目标地址范围 +目标 buffer 所在 location +目标设备列表 +每个设备对应的远端 tseg 字符串 +``` + +这些信息是远端执行 URMA READ/WRITE 的必要条件。 + +## 4. 打开远端 Segment + +在读写之前，发起端通常会调用： + +```cpp +auto target_id = engine.openSegment(remote_server_name); +``` + +逻辑上它会从元数据服务中拿到远端 `SegmentDesc`，并在本地保存一个 `SegmentID` 映射。 + +对 URMA 来说，远端 `SegmentDesc` 至少需要包含： + +```text +protocol = "ub" +devices[] = { device name, EID } +buffers[] = { addr, length, tseg[], location } +topology +``` + +后续 `MultiTransport::selectTransport()` 会根据： + +```cpp +target_segment_desc->protocol +``` + +选择 `transport_map_["ub"]`，也就是 `UbTransport`。 + +## 5. 写流程 + +用户侧写请求： + +```cpp +TransferRequest req;

**参数校验**：检查 client 是否初始化、allocator 是否存在 -2. **分配缓冲区**：`client_buffer_allocator_->allocate(value.size_bytes())` - - 为什么需要分配？因为用户的数据可能在任意内存位置，而 RDMA 传输要求内存必须是"注册过的"（MR，Memory Region）。`client_buffer_allocator_` 分配的就是已注册的 RDMA 内存 -3. **拷贝数据**：`memcpy(buffer_handle.ptr(), value.data(), value.size_bytes())` - - 把用户数据从普通内存拷贝到 RDMA 注册内存 -4. **切分 Slice**：`split_into_slices(buffer_handle)` - - 如果数据量大于 `kMaxSliceSize`（默认 256KB），需要切成多个 Slice。每个 Slice 是一段连续内存的描述符（指针+长度），对应一次 RDMA 写操作 -5. 调用 `client_->Put(key, slices, config)` 进入第3层 - -#### 第3层：Client 服务层（client_service.cpp L1237） - -`Client::Put()` 逻辑如下： - -1. **PutStart**：`master_client_.PutStart(key, slice_lengths, config)` - - 向 Master 发送 RPC，申请为这个 key 分配 replica - - Master 选择目标 segment，返回 replica 描述符列表（每个描述符包含目标内存地址、大小、传输端点等） - - 如果 key 已存在，返回 `OBJECT_ALREADY_EXISTS`，直接返回成功 - - 如果没有可用空间，返回 `NO_AVAILABLE_HANDLE` - -2. **处理磁盘副本**（如果有的话）： - - **逆序遍历** replica 列表（`rbegin/rend`），找磁盘类型的副本 - - 调用 `PutToLocalFile(key, slices, disk_descriptor)` 写本地磁盘 - - **只处理一个磁盘副本就 break** - - > **为什么只处理一个磁盘副本？** 因为磁盘副本是写入本地存储后端的，一个 Client 只有一个 `storage_backend_`，即使 Master 分配了多个磁盘副本描述符，当前 Client 只能写入自己本地的磁盘，无需重复写入。注释也明确说明：`// Only one disk replica is needed`。 - > - > **那其他磁盘副本怎么办？** Master 分配的多个磁盘副本描述符指向不同节点的磁盘。当前 Client 只负责写入自己本地的那个磁盘副本（通过 `storage_backend_`），其他节点的磁盘副本由 Master 协调其他节点来写入，或者由 Master 在后续的 rebalance 流程中补齐。Client 的职责就是：本地有 `storage_backend_` 就写一个本地磁盘副本，其余的不管。 - > - > **为什么必须先处理磁盘副本？** 因为 `PutToLocalFile` 是异步的——数据拼接在调用线程同步完成，但实际磁盘 I/O 和 `PutEnd(DISK)`/`PutRevoke(DISK)` 在 `write_thread_pool_` 中异步执行。先启动磁盘写入，可以尽早触发异步的 `PutEnd(DISK)`，避免与后续内存副本的 `PutEnd(MEMORY)` 产生竞态。 - -3. **处理内存副本**： - - 遍历 replica

**SubmitTransfers**（提交阶段）： - - 对每个未失败的 op： - - 如果有磁盘副本：**逆序遍历找磁盘副本 → `PutToLocalFile()` 写磁盘 → 只处理一个就 break**（与 Put 相同逻辑） - - 对每个内存副本：`transfer_submitter_->submit(replica, slices, WRITE)` 提交异步传输 - - 返回的 `TransferFuture` 存入 `op.pending_transfers` - - 如果任一 replica 提交失败，标记 op 错误，清空 pending_transfers - -4. **WaitForTransfers**（等待阶段）： - - 对每个有 pending_transfers 的 op： - - 遍历所有 `TransferFuture`，调用 `future.get()` 阻塞等待 - - 如果任一传输失败，记录首个错误，标记 op 失败 - - 注意：即使有失败，也会等待所有 future 完成，避免资源泄漏 - -5. **FinalizeBatchPut**（收尾阶段）： - - 将 op 分为三类： - - **传输成功的 op**：调用 `master_client_.BatchPutEnd(successful_keys)` — 批量确认，replica 正式生效 - - **传输失败但已分配 replica 的 op**：调用 `master_client_.BatchPutRevoke(failed_keys)` — 批量撤销，释放 replica - - **早期失败的 op**（未分配 replica）：无需清理 - -6. **CollectResults**： - - 从每个 PutOperation

将用户数据拷贝进去后才能进行零拷贝 RDMA 传输。而 `put_from`/`batch_put_from` 系列要求用户提前通过 `register_buffer()` 注册内存，从而跳过 memcpy 步骤。 - ---- - -### 零拷贝路径详解：put_from / batch_put_from / batch_put_from_multi_buffers - -#### 三者的差异

vLLM 中 KV cache 的多个 layer tensor），每个区域单独注册，然后直接作为 Slice 传入，无需先拼接成连续内存。 - -#### register_buffer 的实现与收益 - -`register_buffer_internal` 的调用链： - -``` -RealClient::register_buffer_internal(buffer, size) - →

-1. **CPU 内存**：调用 `ibv_reg_mr()` 将内存页锁定（pin），并注册到 RDMA 保护域（Protection Domain），获取 `lkey`/`rkey`。锁定后，RDMA NIC 可以直接通过 DMA 访问这些内存，无需 CPU 介入。 -2. **GPU 内存**：通过 CUDA 的 DMA-BUF 机制获取文件描述符，再调用 `ibv_reg_dmabuf_mr()` 注册，RDMA NIC 可以直接从 GPU 显存读取数据并发送到远端，无需先拷贝到 CPU。 - -**register_buffer 的核心收益：** - -1. **消除数据拷贝**：`put_internal` 需要将数据 memcpy 到共享内存池的内部缓冲区，而 `put_from_internal` 直接从已注册的用户缓冲区创建 Slice，省去了这次拷贝。对于大块数据（如 GPU 上的 KV cache tensor），可以显著降低延迟和 CPU 开销。 - -2. **RDMA 零拷贝传输**：`ibv_reg_mr()` 将内存页锁定（pin），RDMA NIC 可以直接通过 DMA 访问这些内存，无需 CPU 介入。未注册的内存无法被 RDMA NIC 直接访问。 - -3. **GPU 内存直传**：通过 `ibv_reg_dmabuf_mr()` 注册 GPU 内存，RDMA NIC 可以直接从 GPU 显存读取数据并发送到远端，无需先拷贝到 CPU 再发送。 - -4. **一次注册，多次使用**：`register_buffer` 通常在初始化阶段调用一次（例如 vLLM 启动时注册整个 KV cache 内存池），之后所有 `put_from`/`get_into` 操作都可以零拷贝地复用该注册。`ibv_reg_mr` 本身是一个昂贵的操作（涉及页表锁定和 NIC 映射），避免每次操作都重新注册是关键优化。 - -5. **子区域支持**：通过 `resolve_registered_buffer`，注册一个大区域后，可以对其中的任意子区域进行零拷贝操作，灵活支持 tensor 切片等场景。 - ---- - -### PutToLocalFile：磁盘副本写入机制 - -`PutToLocalFile`（client_service.cpp L2593）的完整流程： - -**阶段1：同步数据暂存（调用线程）** - -1. 遍历所有 Slice，计算总大小 -2. 对每个 Slice： - - 如果是 GPU 指针（`IsDevicePointer` 检测）→ 通过 Pinned Buffer Pool 做 D2H（Device-to-Host）拷贝，暂存到 `std::string` - - 如果是普通主机内存指针 → 直接 append 到 `std::string` -3. 这一步必须在调用线程同步完成，因为 BatchPut 还未返回给 Python，GPU buffer 不会被复用 - -**阶段2：异步磁盘写入（write_thread_pool_）** - -1. `storage_backend_->StoreObject(path, value, key)` 写入磁盘文件 -2. 写入成功 → `master_client_.PutEnd(key, DISK)` + 处理驱逐通知 -3. 写入失败 → `master_client_.PutRevoke(key, DISK)` - -**磁盘写入没有使用 RDMA 或高速网络通道**。内存副本通过 `TransferWrite` → `transfer_submitter_` 走传输引擎（可能使用 RDMA/TCP），但磁盘副本走的是纯本地文件 I/O 路径。 - -底层文件 I/O 有三种实现（根据编译选项和配置选择）： - -| 后端 | 条件 | 特点 | -|------|------|------| -| **PosixFile** | 默认 | POSIX `preadv`/`pwritev`，普通本地文件 I/O | -| **UringFile** | 编译时 `USE_URING` + 运行时配置 | Linux `io_uring` 异步 I/O，读操作启用 `O_DIRECT` 绕过页缓存 | -| **ThreeFSFile** | 编译时 `USE_3FS` | 3FS 分布式文件系统（高性能用户态文件系统），通过 `hf3fs_reg_fd` 注册 | - -此外，存储后端有三种架构模式： - -| 模式 | 类名 | 特点 | -|------|------|------| -| `kFilePerKey` | `StorageBackendAdaptor` | 每个 key 一个文件，序列化为 protobuf | -| `kBucket` | `BucketStorageBackend` | 多个 key 聚合到一个 bucket 文件，支持 FIFO/LRU 驱逐 | -| `kOffsetAllocator` | `OffsetAllocatorStorageBackend` | 单一预分配数据文件 + offset allocator | - -**总结**：磁盘副本的写入就是普通的本地文件 I/O，没有 RDMA。可选的 `io_uring` 和 `3FS` 是本地 I/O 路径上的优化，不是网络传输加速。GPU 数据需要先做 D2H 拷贝到主机内存，再写入磁盘。 - ---- - -## 第二部分：Get/GetBatch - -### Get 的完整底层逻辑（单 key） - -#### 第1层：Python 绑定（store_py.cpp L398） - -``` -store.get(key) → py::bytes -``` - -1.

DISK** -4. **计算对象总大小**：`calculate_total_size(replica)` -5. 返回 `RangedReadMetadata{query_result, replica, total_size}` - -#### 第4层：执行读取（real_client.cpp::execute_ranged_read） - -`execute_ranged_read()` 先按**读取范围**分为完整读取和部分读取，再按**副本类型**分为 MEMORY / DISK / LOCAL_DISK。这样分不是为了复杂化逻辑，而是因为这两个维度决定了能不能直接把数据写进用户 buffer： - -- **读取范围决定能不能直接使用底层能力**：完整读取通常可以直接复用 `Client::Get` / SSD offload，把整个对象一次性写入目标 buffer；部分读取只需要对象的一段，如果底层路径不支持源 offset 或不能随机读，就必须先读到临时 buffer 再截取。 -- **副本类型决定数据从哪里来、用什么 I/O 读**： - - MEMORY：数据在内存副本中，可以通过 Transfer Engine / 本地 memcpy 直接读到用户 buffer。 - - DISK：数据在当前节点本地文件中，文件 I/O 写入 GPU buffer 不安全或不可用，所以通常需要 CPU 临时 buffer。 - - LOCAL_DISK：数据在远端节点 SSD 中，当前节点不能直接读这个文件，只能让远端节点 offload 读取，再通过网络传回来。 - -1. **容量/范围检查** - - `size_is_buffer_capacity=true` 时：要求 `size >= total_size`，然后实际读取大小设为 `total_size` - - 范围读时：要求 `src_offset + size <= total_size` - -2. **为什么先区分完整读取和部分读取** - - `get_into(key, buffer, size)` 走的是完整读取路径：`src_offset=0`，目标是把整个对象读出来。此时如果 `size >= total_size`，就可以把实际读取大小设成 `total_size`，尽量走最直接的路径。 - - `get_into_range` / `get_into_ranges` 这类范围读只需要对象中的一段，例如 `[src_offset, src_offset + size)`。范围读不能简单复用完整读取逻辑，否则会把不需要的数据也搬到用户 buffer，甚至覆盖用户不希望写入的区域。因此： - - - MEMORY 路径支持源 offset，可以直接从 `src_offset` 开始读。 - - DISK 路径当前依赖 `allocateSlices` / `Client::Get` 的完整对象切片模型，不能只为任意范围构造完整正确的文件读请求，所以先读完整对象到临时 buffer，再 scatter 目标范围。 - - LOCAL_DISK offload 当前也是从远端 offset 0 顺序读取，不能直接告诉远端“只读 src_offset 之后这一段”，所以读 `[0, src_offset + size)` 到临时 buffer，再取目标范围。 - -3. **完整对象读取：`src_offset == 0 && size == total_size`** - - **[分支A] LOCAL_DISK 副本**： - - **为什么这样读**：LOCAL_DISK 表示对象文件在远端节点的本地 SSD 上。当前节点既没有这个本地文件，也不能通过普通文件 I/O 读取它，所以必须让远端节点执行 SSD 读取。 - - **怎么读**： - - 构造 `objects[key] = {Slice{buffer + dst_offset, total_size}}` - - 调用 `batch_get_into_offload_object_internal(endpoint, objects)` - - 远端节点从 SSD 读到 offload buffer - - 再通过 Transfer Engine 把数据写入当前用户 buffer - - **为什么可以直接写用户 buffer**：完整对象读取时目标区域正好是整个对象大小，用户 buffer 容量已校验足够，因此不需要中间裁剪。 - - **[分支B] DISK 副本**： - - **为什么不直接写用户 buffer**：DISK 走本地文件 I/O。用户 buffer 可能是 GPU / Ascend / 其他设备内存，普通文件 I/O 不能保证能直接写入这些地址；即使是 CPU 地址，也需要统一处理设备场景。 - - **怎么读**： - - 先用 `client_buffer_allocator_->allocate(total_size)` 分配 CPU 临时 buffer - - `allocateSlices(tmp_slices, replica, tmp_handle.ptr())` - - `client_->Get(key, filtered_qr, tmp_slices)` 从本地磁盘读到临时 buffer - - `scatter_host_to_maybe_device(buffer + dst_offset, tmp_handle.ptr(), total_size, ...)` 再把数据搬到用户 buffer - - **为什么完整读取仍要临时 buffer**：这里的限制来自目标内存类型，不是读取范围。只要目标可能是设备内存，DISK 文件读就先落到 CPU buffer，再由 scatter 处理 CPU/GPU 拷贝差异。 - - **[分支C] MEMORY 副本**： - - **为什么可以直接写用户 buffer**：MEMORY 副本由 Transfer Engine / memcpy 传输，目标地址可以是已注册的用户 buffer，适合零拷贝读。 - - **怎么读**： - - `allocateSlices(slices, replica, buffer + dst_offset)` - - `FilterQueryResult(query_result, replica)`，确保 `Client::Get` 只看到选中的副本 - - `client_->Get(key, filtered_qr, slices)` 直接把远端/本地内存副本读入用户 buffer - - **为什么这是最快路径**：不需要分配临时 buffer，也不需要读后 scatter；数据从内存副本直接进入调用方提供的目标区域。 - -4. **部分读取：`src_offset != 0` 或 `size < total_size`** - - **[分支A] LOCAL_DISK 范围读**： - - **为什么不能直接读目标范围**：当前 offload RPC 的对象描述只有目标 slices，没有表达“从远端文件 src_offset 开始读”的接口语义；远端按对象起点顺序读取。 - - **为什么临时 buffer 大小是 `src_offset + size`**：只需要读到目标范围的结尾即可，不必读完整对象。比如要读 `[100, 120)`，远端读 `[0, 120)`，本地再取后 20 字节。 - - **怎么读**： - - 分配 `src_offset + size` 的 CPU 临时 buffer - - offload 读取 `[0, src_offset + size)` 到临时 buffer - - scatter `[src_offset, src_offset + size)` 到用户 buffer - - **[分支B] DISK 范围读**： - - **为什么读完整对象**：DISK 路径复用 `Client::Get + allocateSlices` 的文件读逻辑，它按对象副本切片构造读取任务；为了保持和完整对象切片、磁盘 descriptor、设备 scatter 的处理一致，当前实现先读完整对象。 - - **为什么不能直接写用户范围**：同完整读取一样，目标 buffer 可能是设备内存，文件 I/O 不直接写设备地址。 - - **怎么读**： - - 分配 `total_size` 的 CPU 临时 buffer - - 通过 `client_->Get` 读完整对象 - - scatter `[src_offset, src_offset + size)` 到 `buffer + dst_offset` - - **[分支C] MEMORY 范围读**： - - **为什么可以直接范围读**：内存传输路径支持传入源 offset，`client_->Get(key, query_result, slices, src_offset)` 可以让 Transfer 层从对象的 `src_offset` 开始搬运。 - - **怎么读**： - - 构造单个目标 `Slice{buffer + dst_offset, size}` - - 调用 `client_->Get(key, query_result, slices, src_offset)` - - Transfer 层从源对象的 `src_offset` 开始读取，直接写入用户 buffer - - **为什么不需要临时 buffer**：源端支持 offset，目标端用户 buffer 已注册并且只写目标范围，所以没有裁剪或设备文件 I/O 的问题。 - -5. **整体决策表** - -| 读取类型 | MEMORY | DISK | LOCAL_DISK | -|---------|--------|------|------------| -| 完整读取 | 直接 `Client::Get` 到用户 buffer | 文件 I/O 到 CPU 临时 buffer，再 scatter | 远端 SSD offload 直接写用户 buffer | -| 部分读取 | `Client::Get(..., src_offset)` 直接读范围 | 读完整对象到 CPU 临时 buffer，再 scatter 范围 | 读 `[0, src_offset + size)` 到 CPU 临时 buffer，再 scatter 范围 | - -这张表背后的核心原则是：**能表达 offset 且能安全写用户 buffer 的路径就直接读；不能表达 offset 或不能安全写用户 buffer 的路径，就先读到 CPU 临时 buffer，再由 scatter 精确写入目标范围。** - -#### 第5层：Client 服务层 - -MEMORY / DISK 分支最终仍复用 `Client::Get`： - -1.

-**`isLocalTransfer` 的判断**：将副本的 `transport_endpoint_` 与 `engine_.getLocalIpAndPort()` 比较，相同则说明数据在本机，走 memcpy；否则走 Transfer Engine 远程传输。 - -**注意**：`submit()` 的 `is_memory_replica() == false` 分支（即 `submitFileReadOperation`）只处理 DISK 副本，**不处理 LOCAL_DISK**。LOCAL_DISK 在 RealClient 层就被提前拦截，走独立的 RPC 路径。 - ---- - -### 深度解析2：LOCAL_DISK 为什么不能走策略模式？ - -LOCAL_DISK 不能走 `TransferSubmitter::submit()` 的策略模式，根本原因是**数据不在本机，也不在共享文件系统上，而是在远端 Worker 节点的本地 SSD 上**。 - -三种副本的数据位置和访问方式完全不同： - -| 副本类型 | 数据位置 | 访问方式 | -|---------|---------|---------| -| **MEMORY** | 某个节点的内存中（有 `buffer_address` + `transport_endpoint`） | 直接通过传输引擎 RDMA/TCP 读取，或本地 memcpy | -| **DISK** | 本机的共享文件系统路径（有 `file_path`） | 本地文件 I/O（`FilereadWorkerPool`） | -| **LOCAL_DISK** | 远端 Worker 节点的本地 SSD（有 `client_id` + `transport_endpoint`） | **两阶段**：先 RPC 让远端从 SSD 读到内存，再通过传输引擎拉取 | - -LOCAL_DISK 无法走策略模式的原因： - -**1. 需要先触发远端 SSD 读取** - -MEMORY 副本的数据已经在内存中，`buffer_address` 直接可用；DISK 副本的 `file_path` 在本机，可以直接文件 I/O。但 LOCAL_DISK 的数据在远端 SSD 上，**远端必须先执行一次 SSD → 内存的数据搬运**，客户端才能通过传输引擎读取。这个"远端 SSD 读取"步骤无法在 `submit()` 内部完成，因为 `submit()` 只负责本机侧的传输调度。 - -**2. 两阶段协议需要状态协调** - -LOCAL_DISK 的完整读取流程： - -``` -客户端 远端 Worker 节点 - | | - |--- RPC: batch_get_offload_object ------->| 1. FileStorage::BatchGet() - | (keys, sizes) | AllocateBatch() → 分配对齐内存缓冲区 - | | BatchLoad() → 从 SSD 读取到缓冲区 - |<--- RPC Response -----------------------| 返回 {pointers, transfer_engine_addr, gc_ttl_ms} - | | - |=== RDMA/传输引擎 READ ===================| 2. 传输引擎将远端缓冲区数据拉到本地 - | source=本地slice地址 | (远端内存 → 本地内存/GPU显存) - | target=远端segment+pointer偏移 | - | | - |--- RPC: release_offload_buffer --------->| 3. 释放远端缓冲区（fire-and-forget） - | | -``` - -这个两阶段协议涉及：RPC 调用 → 等待远端 SSD I/O → 获取远端内存地址 → 传输引擎拉取 → 释放远端缓冲区。中间有多个状态需要协调（远端缓冲区的分配、GC 租约、主动释放），无法用 `submit()` 的单次提交+等待模式表达。 - -**3. 远端缓冲区有生命周期管理** - -远端 Worker 为 LOCAL_DISK 读取分配了临时内存缓冲区，有 `gc_ttl_ms`（默认 5000ms）租约。如果客户端超时未完成传输，远端 GC 线程会回收缓冲区，数据丢失。客户端必须在传输完成后主动调用 `release_offload_buffer` 释放，加速缓冲区回收。这种跨节点的缓冲区生命周期管理超出了 `TransferSubmitter` 的职责范围。 - ---- - -### 深度解析3：LOCAL_DISK 的读取速度比 DISK 快吗？ - -**通常 LOCAL_DISK 更快**，原因如下： - -**1. 传输路径对比** - -| 阶段 | DISK | LOCAL_DISK | -|------|------|------------| -| 数据位置 | 本机共享文件系统 | 远端 Worker SSD | -| 读取方式 | 本地文件 I/O（preadv/io_uring） | 远端 SSD → 远端内存 → RDMA → 本地 | -| 目标内存 | 只能写 CPU 内存 | 可直接写 GPU 内存 | -| 网络开销 | 无 | 有（RPC + RDMA） | - -**2. 为什么 LOCAL_DISK 通常更快？** - -- **SSD 性能优势**：LOCAL_DISK 存储在 Worker 节点的本地 NVMe SSD 上，随机读写性能远高于 DISK 使用的共享文件系统（可能是 NFS、CephFS 等网络文件系统，或普通 HDD） -- **并行读取**：LOCAL_DISK 的远端 Worker 使用专用线程池并行从 SSD 读取（`coro_io::post`），然后通过 RDMA 高速传输回来；DISK 的本地文件 I/O 虽然也用 `FilereadWorkerPool`（10线程），但受限于共享文件系统的 I/O 能力 -- **GPU 直写**：LOCAL_DISK 通过 RDMA 传输可以直接写入 GPU 内存（用户通过 `register_buffer` 预注册），而 DISK 的本地文件 I/O 只能写 CPU 内存，如果目标是 GPU 内存还需要额外的 D2H 中转 -- **io_uring 优化**：LOCAL_DISK 的远端 Worker 读取 SSD 时可以使用 io_uring + O_DIRECT 零拷贝读取，避免内核态拷贝 - -**3. 什么情况下 DISK 可能更快？** - -- 数据量很小（网络开销占比大） -- 本地共享文件系统使用 NVMe SSD 且网络带宽有限 -- RDMA 网络不可用，回退到 TCP 传输 - -**4. 速度排序总结** - -``` -本地 MEMORY（memcpy）> 远端 MEMORY（RDMA）> LOCAL_DISK（远端SSD+RDMA）> DISK（本地文件I/O） -``` - -这个排序与 `SelectBestReplica` 的优先级一致：系统自动选择最快的可用副本。 - ---- - -### 深度解析4：为什么 LOCAL_DISK 优先级高于 DISK？ - -`SelectBestReplica` 的优先级：**本地 MEMORY > 远端 MEMORY > LOCAL_DISK > DISK** - -LOCAL_DISK 优先于 DISK 的原因： - -**1. 数据来源的可靠性不同** - -| 维度 | DISK | LOCAL_DISK | -|------|------|------------| -| 数据位置 | Master 管理的共享文件系统路径（`file_path`） | Worker 节点的本地 SSD | -| 创建者 | Master 在 PutStart 时自动创建 | Worker 完成数据卸载后通知 Master 创建 | -| 归属关系 | 无 client_id，全局共享 | 绑定到特定 client_id + transport_endpoint | -| 生命周期 | 随对象存在 | 绑定到客户端，客户端失活时被清理 | - -LOCAL_DISK 的数据由活跃 Worker 写入并管理，数据新鲜且确定可用；而 DISK 是 Master 侧共享文件系统上的数据，可能存在路径解析、文件系统可用性等额外风险。 - -**2. 传输路径的灵活性不同** - -- **LOCAL_DISK**：RPC + RDMA 传输路径，数据可以直接写入 GPU 内存（用户通过 `register_buffer` 预注册） -- **DISK**：本地文件 I/O（`FilereadWorkerPool`），只能写 CPU 可寻址的内存，如果分配器返回了 GPU 内存则读取会失败，需要额外的临时 CPU 缓冲区中转 - -**3. 架构定位不同** - -LOCAL_DISK 是较新的架构设计——当内存不足时，Worker 将 MEMORY 副本卸载（offload）到本地 SSD，形成 MEMORY → LOCAL_DISK 的降级路径。这是数据生命周期中的自然降级，数据仍然由活跃 Worker 管理。而 DISK 是更早期的、由 Master 直接管理的共享存储机制，属于完全不同的存储层。 - -**4. transport_endpoint 的含义差异** - -| 副本类型 | transport_endpoint 含义 | -|---------|----------------------| -| MEMORY | 内存段所在节点的传输引擎端点（RDMA NIC 地址） | -| DISK | 无 transport_endpoint（DiskDescriptor 中没有此字段） | -| LOCAL_DISK | 拥有该 SSD 数据的 Worker 节点的 **RPC 服务地址** | - -LOCAL_DISK 有明确的 `transport_endpoint`（Worker 的 RPC 地址），客户端可以直接发起远程读取；而 DISK 没有远程端点，只能本地文件 I/O。 - ---- - -### 深度解析5：为什么使用了 Hot Cache 就要释放？ - -在 `Client::Get` 和 `Client::BatchGet` 中，如果使用了 Hot Cache（`cache_used=true`），在数据传输完成后必须调用 `ReleaseHotKey(key)`。这不是"释放缓存数据"，而是**释放对缓存块的引用计数**。 - -**Hot Cache 的引用计数机制：** - -``` -GetHotKey(key) → ref_count++ （获取引用，保护缓存块不被驱逐） - ↓ -数据传输/memcpy → 从 blk->addr 读取数据到用户 buffer - ↓ -ReleaseHotKey(key) → ref_count-- （释放引用，允许缓存块重新可被驱逐） -``` - -**`GetHotKey` 做了什么？**（local_hot_cache.cpp L115） - -1. 在 `key_to_lru_it_` 中查找 key -2. 找到后 `ref_count++`（原子操作）——这相当于对缓存块加了一把"读锁" -3. `accessed = true`（延迟 LRU touch 标志） -4. 返回 `HotMemBlock*` 指针 - -**`RedirectToHotCache` 做了什么？**（client_service.cpp L1212） - -1. 调用 `GetHotKey(key)` 获取缓存块（`ref_count++`） -2. 将 replica 的 `buffer_address_` 改为缓存块的内存地址 `blk->addr` -3. 将 `transport_endpoint_` 改为本地地址（变为本地 memcpy 传输） - -**`ReleaseHotKey` 做了什么？**（local_hot_cache.cpp L136） - -1. 在 `key_to_lru_it_` 中查找 key -2. `ref_count--`（原子操作） - -**如果不释放会怎样？** - -`ref_count` 永远不为 0，该缓存块在 `GetFreeBlock()` 中会被跳过，永远无法被驱逐和重用。随着时间推移，越来越多的块被"锁死"，可用缓存容量持续减少，最终导致 Hot Cache 完全失效——`GetFreeBlock()` 返回 `nullptr`，新数据无法进入缓存。 - -**为什么不在传输前就释放？** - -因为 `RedirectToHotCache` 将传输目标重定向到了缓存块的内存地址。如果提前释放引用，缓存块可能被其他线程驱逐（`GetFreeBlock` 会驱逐 `ref_count == 0` 的块），其内存可能被新数据覆盖，导致当前传输读到脏数据。必须在 `future.get()` 确认传输完成后才能释放——此时 memcpy 已经完成，数据已经安全拷贝到用户 buffer 中。 - ---- - -## 第三部分：Put vs Get 对比 - -| 维度 | Put | Get | -|------|-----|-----| -| Master 交互 | PutStart → PutEnd/PutRevoke | Query → 无需再通知 Master | -| 副本处理 | 写入所有内存副本 + 1个磁盘副本 | 只读1个最优副本 | -| 传输方向 | WRITE（本地→远端） | READ（远端→本地） | -| 数据拷贝 | 需要 memcpy 到 RDMA 注册内存 | 需要 allocate 缓冲区接收数据 | -| 零拷贝路径 | `put_from`（用户 buffer 已注册） | `get_into`（用户 buffer 已注册） | -| Hot Cache | 不涉及 | 有频率准入机制（CountMinSketch） | -| 失败恢复 | PutRevoke 撤销 replica | 无需撤销，换副本重试或返回错误 | -| 磁盘写入 | `PutToLocalFile`（异步线程池写磁盘） | 不涉及（Get 只读磁盘） | -| Lease | 不涉及 | 有 Lease 过期检查 | diff --git a/docs/yh/transfer-engine-deep-dive.md b/docs/yh/transfer-engine-deep-dive.md deleted file mode 100644 index 47c2e3cf88..0000000000 --- a/docs/yh/transfer-engine-deep-dive.md +++ /dev/null @@ -1,1203 +0,0 @@ -# Mooncake Transfer Engine 深度解析 -

-``` - -然后对每个设备创建 context： - -```cpp -context = std::make_shared(*transport, device_name, max_endpoints); -context->doConstruct(config); -``` - -`UbContext::doConstruct()` 做两件事： - -```text -1. 调用 UrmaContext::construct(config) -2. 创建 endpoint_store_，用于按 peer_nic_path 缓存 UrmaEndpoint -``` - -### 2.5 UrmaContext::construct() - -`UrmaContext::construct()` 是每张 UB device 的底层资源初始化： - -```text -UrmaContext::construct() - -> openDevice(device_name, port, eid_index) - -> urma_create_jfce() 创建完成事件队列 - -> epoll 监听 async fd - -> urma_create_jfc() 创建发送完成队列 - -> urma_create_jfc() 创建接收完成队列 - -> urma_create_jfr() 创建接收队列 - -> 启动 UbWorkerPool -``` - -其中 `openDevice()` 会调用 URMA 设备枚举和打开逻辑，并得到当前 device 的 EID。EID 会在后续握手时发给对端。 - -### 2.6 发布本地 SegmentDesc - -`UbTransport::allocateLocalSegmentID()` 创建本地 segment 描述： - -```cpp -desc->name = local_server_name_; -desc->protocol = "ub"; -for (auto& context : context_list_) { - device_desc.name = context->deviceName(); - device_desc.eid = context->getEid(); - desc->devices.push_back(device_desc); -} -desc->topology = *local_topology_; -``` - -这一步发布的是节点级信息： - -```text -server name -protocol = ub -设备列表 device name + EID -拓扑矩阵 -``` - -此时还没有内存 buffer 信息。内存 buffer 会在 `registerLocalMemory()` 后追加到本地 `SegmentDesc`。 - -### 2.7 启动握手服务 - -`UbTransport::startHandshakeDaemon()` 注册被动握手回调： - -```cpp -metadata_->startHandshakeDaemon( - std::bind(&UbTransport::onSetupConnections, this, ...), - rpc_port, - sockfd); -``` - -这表示对端后续第一次向本节点某个 UB device 传输时，可以通过 RPC 调用本节点的 `onSetupConnections()`，完成 Jetty 绑定。 - -### 2.8 更新元数据 - -最后： - -```cpp -metadata_->updateLocalSegmentDesc(); -``` - -把本节点的 `SegmentDesc` 发布到元数据服务中。对端通过 `openSegment()` 或 `getSegmentDescByName()` 能拿到它。 - -## 3. 内存注册流程 - -用户调用： - -```cpp -engine.registerLocalMemory(addr, length, location); -``` - -调用链： - -```text -TransferEngine::registerLocalMemory() - -> TransferEngineImpl::registerLocalMemory() - -> MultiTransport 中每个已安装 transport 注册 - -> UbTransport::registerLocalMemory() - -> 每个 UrmaContext::registerMemoryRegion() - -> 每个 UrmaContext::buildLocalBufferDesc() - -> metadata_->addLocalMemoryBuffer() -``` - -### 3.1 在每个 URMA 设备上注册 segment - -`UbTransport::registerLocalMemory()` 遍历所有 `context_list_`： - -```cpp -for (auto& context : context_list_) { - context->registerMemoryRegion((uint64_t)addr, length); - context->buildLocalBufferDesc((uint64_t)addr, buffer_desc); -} -``` - -也就是说，同一块用户内存会在每个可用 UB device 上注册一次。原因是后续 `selectDevice()` 可能选择任意一个 device；每个 device 都需要自己的可访问 segment handle。 - -`UrmaContext::registerMemoryRegion()` 主要做： - -```text -1. 构造 urma_reg_seg_flag_t - - token_policy = URMA_TOKEN_NONE - - cacheable = URMA_NON_CACHEABLE - - access = READ | WRITE | ATOMIC - -2. 构造 urma_seg_cfg_t - - va = 用户虚拟地址 - - len = 注册长度 - - token_value = urma_token - -3. 调用 urma_register_seg() - -4. 保存返回的 urma_target_seg_t* - - local_tseg_list_ - - seg_region_list_ -``` - -`seg_region_list_` 用于根据地址反查本地 tseg；`local_tseg_list_` 用于根据 metadata 中的 index 快速取出本地 segment。 - -### 3.2 构建 BufferDesc - -注册完以后，`UrmaContext::buildLocalBufferDesc()` 会把 URMA segment 序列化： - -```cpp -auto str = serializeBinaryData(&seg(addr)->seg, sizeof(urma_seg_t)); -buffer_desc.tseg.push_back(str); -buffer_desc.l_seg_index.push_back(index); -``` - -`BufferDesc` 中和 URMA 相关的关键字段是： - -```text -addr 本地 buffer 起始地址 -length buffer 长度 -name 内存位置，例如 cpu:0 / * / cuda:0 -tseg[] 每个 device 对应的序列化 urma_seg_t -l_seg_index[] 每个 device 对应的本地 tseg 索引 -``` - -### 3.3 自动识别内存位置 - -如果用户传入的 location 是 `"*"`： - -```cpp -getMemoryLocation(addr, length, only_first_page = true) -``` - -Mooncake 会尝试识别这块内存属于哪个 NUMA node 或设备，然后写入 `buffer_desc.name`。后续设备选择会优先使用与这个 location 更近的 UB device。 - -如果用户显式传入 `cpu:0`、`cpu:1` 等 location，则直接使用用户传入的值。 - -### 3.4 更新元数据 - -最后： - -```cpp -metadata_->addLocalMemoryBuffer(buffer_desc, update_metadata); -``` - -这样远端才能通过元数据拿到： - -```text -目标地址范围 -目标 buffer 所在 location -目标设备列表 -每个设备对应的远端 tseg 字符串 -``` - -这些信息是远端执行 URMA READ/WRITE 的必要条件。 - -## 4. 打开远端 Segment - -在读写之前，发起端通常会调用： - -```cpp -auto target_id = engine.openSegment(remote_server_name); -``` - -逻辑上它会从元数据服务中拿到远端 `SegmentDesc`，并在本地保存一个 `SegmentID` 映射。 - -对 URMA 来说，远端 `SegmentDesc` 至少需要包含： - -```text -protocol = "ub" -devices[] = { device name, EID } -buffers[] = { addr, length, tseg[], location } -topology -``` - -后续 `MultiTransport::selectTransport()` 会根据： - -```cpp -target_segment_desc->protocol -``` - -选择 `transport_map_["ub"]`，也就是 `UbTransport`。 - -## 5. 写流程 - -用户侧写请求： - -```cpp -TransferRequest req; -req.opcode = TransferRequest::WRITE; -req.source = local_addr; -req.target_id = remote_segment_id; -req.target_offset = remote_addr_or_offset; -req.length = length; - -auto batch = engine.allocateBatchID(1); -engine.submitTransfer(batch, {req}); -``` - -完整调用链： - -```text -TransferEngine::submitTransfer() - -> TransferEngineImpl::submitTransfer() - -> MultiTransport::submitTransfer() - -> selectTransport(req) - 根据 target SegmentDesc.protocol 选择 UbTransport - -> UbTransport::submitTransferTask() - -> 查找本地 buffer/device - -> 按 slice_size 拆分 Slice - -> 为每个 Slice 填充本地 l_seg - -> 按本地 UrmaContext 分组 - -> UrmaContext::submitPostSend() - -> UbWorkerPool::submitPostSend() - -> 查找远端 buffer/device - -> import 远端 tseg - -> 按 peer_nic_path 入队 - -> worker 线程 performPostSend() - -> 获取/创建 UrmaEndpoint - -> 必要时主动握手 - -> UrmaEndpoint::submitPostSend() - -> urma_post_jetty_send_wr() -``` - -### 5.1 选择本地设备 - -`UbTransport::submitTransferTask()` 先尝试判断整个 request 是否落在同一个本地 buffer： - -```cpp -selectDevice(local_segment_desc, request.source, request.length, - request_buffer_id, request_device_id) -``` - -如果能整体命中，后续每个 slice 复用同一个 `buffer_id/device_id`。这是一个优化，避免每个 slice 都重新查找。 - -如果整体不能命中，则每个 slice 单独执行： - -```cpp -selectDevice(local_segment_desc, slice->source_addr, slice->length, - buffer_id, device_id, retry_cnt) -``` - -`selectDevice()` 的逻辑是： - -```text -1. 遍历本地 SegmentDesc.buffers -2. 找到覆盖 source_addr + length 的 BufferDesc -3. 用 buffer.name 到 topology 中选择 device -4. 如果按 location 找不到，就用 "*" fallback -5. 返回 buffer_id 和 device_id -``` - -### 5.2 Slice 分片 - -大请求按 `globalConfig().slice_size` 拆成多个 slice： - -```text -request.length = 3.5 MB -slice_size = 1 MB - -Slice0 1 MB -Slice1 1 MB -Slice2 1 MB -Slice3 0.5 MB -``` - -如果最后一段长度小于 `slice_size + fragment_limit`，会合并为最后一个 slice，减少碎片。 - -每个 slice 会记录： - -```text -source_addr -length -opcode = WRITE -target_id -ub.dest_addr = request.target_offset + offset -retry_cnt -max_retry_cnt -task 指针 -``` - -### 5.3 填充本地 l_seg - -找到本地 `buffer_id/device_id` 后： - -```cpp -auto local_tseg_index = - local_segment_desc->buffers[buffer_id].l_seg_index[device_id]; -slice->ub.l_seg = context->localSegWithIndex(local_tseg_index); -``` - -`l_seg` 是本地 URMA segment handle。WRITE 时它作为源端 segment。 - -### 5.4 提交到 UbWorkerPool - -slice 会按本地 `UrmaContext` 分组： - -```cpp -slices_to_post[context].push_back(slice); -``` - -达到水位线后，或者所有 slice 处理完后： - -```cpp -context->submitPostSend(slice_list); -``` - -`UrmaContext::submitPostSend()` 本身只是转给 worker pool： - -```cpp -worker_pool_->submitPostSend(slice_list); -``` - -### 5.5 查找远端目标设备和 r_seg - -`UbWorkerPool::submitPostSend()` 对每个 slice： - -```text -1. 根据 target_id 获取远端 SegmentDesc -2. 根据 ub.dest_addr + length 在远端 buffers 中找目标 BufferDesc -3. 用远端 topology 选择远端 device -4. 取出 peer_segment_desc->buffers[buffer_id].tseg[device_id] -5. context_.retrieveRemoteSeg(targetSegment) -6. 构造 peer_nic_path = remote_server + remote_device -7. 按 peer_nic_path 入队 -``` - -这里有一个重要细节： - -```cpp -auto hint = globalConfig().enable_dest_device_affinity - ? context_.deviceName() - : ""; -``` - -如果启用了目标设备亲和，远端选 device 时会优先尝试和本地 device 同名或匹配 hint 的设备，尽量形成稳定的本地/远端设备配对。 - -### 5.6 导入远端 segment - -远端 `tseg` 是序列化后的 `urma_seg_t` 字符串。发起端需要把它导入到本地 URMA context： - -```cpp -slice->ub.r_seg = context_.retrieveRemoteSeg(targetSegment); -``` - -`UrmaContext::retrieveRemoteSeg()` 做： - -```text -1. 查 import_tseg_map 缓存 -2. 反序列化 remoteSegmentStr -> urma_seg_t -3. 调用 urma_import_seg() -4. 缓存 import_tseg_map[remoteSegmentStr] -5. 返回 imported target segment -``` - -WRITE 时，`r_seg` 是远端目标内存 segment。 - -### 5.7 建立 Endpoint - -worker 线程执行 `performPostSend()` 时，以 `peer_nic_path` 为 key 获取 endpoint： - -```cpp -auto endpoint = context_.endpoint(peer_nic_path); -``` - -如果 endpoint 不存在，`UbContext::endpoint()` 会创建并缓存： - -```text -UbSIEVEEndpointStore - peer_nic_path -> UrmaEndpoint -``` - -如果 endpoint 尚未 connected： - -```cpp -endpoint->setupConnectionsByActive(); -``` - -这会触发 URMA Jetty 主动握手。 - -### 5.8 提交 URMA WRITE - -连接建立后： - -```cpp -endpoint->submitPostSend(slice_vector, failed_slice_list); -``` - -`UrmaEndpoint::submitPostSend()` 的关键步骤： - -```text -1. 随机选择一个 Jetty -2. 检查 Jetty WR 深度和 JFC outstanding 深度 -3. 为每个 slice 构造 urma_jfs_wr_t -4. WRITE 时： - src.sge = 本地 source_addr + l_seg - dst.sge = 远端 dest_addr + r_seg -5. 设置 wr.user_ctx = slice -6. 设置 wr.tjetty = imported remote jetty -7. 标记 slice 为 POSTED -8. 调用 urma_post_jetty_send_wr() -``` - -WRITE 的数据方向： - -```text -本地 source_addr / l_seg - -> URMA Jetty - -> 远端 ub.dest_addr / r_seg -``` - -## 6. 读流程 - -READ 请求和 WRITE 使用同一套 `submitTransferTask()`、worker、endpoint、完成轮询逻辑，差异主要在 opcode 和 SGE 方向。 - -用户请求： - -```cpp -TransferRequest req; -req.opcode = TransferRequest::READ; -req.source = local_addr; -req.target_id = remote_segment_id; -req.target_offset = remote_addr_or_offset; -req.length = length; -``` - -在 `UrmaEndpoint::submitPostSend()` 中： - -```cpp -wr.opcode = URMA_OPC_READ; -wr.rw.src.sge = &r_sge; -wr.rw.dst.sge = &l_sge; -``` - -READ 的数据方向： - -```text -远端 ub.dest_addr / r_seg - -> URMA Jetty - -> 本地 source_addr / l_seg -``` - -所以 `TransferRequest::source` 在 Mooncake API 中始终是本地地址： - -- WRITE：本地地址是源。 -- READ：本地地址是目标。 - -`target_offset` 始终描述远端地址。 - -## 7. URMA 握手与 Jetty 绑定 - -URMA 路径使用 Transfer Engine 的 RPC handshake，不使用 RDMA CM。 - -### 7.1 主动端 - -主动端在 worker 线程中发现 endpoint 未连接时调用： - -```cpp -UrmaEndpoint::setupConnectionsByActive() -``` - -主动端构造 `HandShakeDesc`： - -```cpp -local_desc.local_nic_path = context_->nicPath(); -local_desc.peer_nic_path = peer_nic_path_; -local_desc.jetty_num = JettyNum(); -``` - -然后发 RPC： - -```cpp -context_->engine().sendHandshake(peer_server_name, local_desc, peer_desc); -``` - -收到对端返回后，主动端从远端 `SegmentDesc` 中找到目标 device 的 EID： - -```cpp -doSetupConnection(peer_eid, peer_desc.jetty_num); -``` - -### 7.2 被动端 - -被动端 handshake daemon 收到 RPC 后进入： - -```text -UbTransport::onSetupConnections() - -> 根据 peer_desc.peer_nic_path 找本地 context - -> context->endpoint(peer_desc.local_nic_path) - -> endpoint->setupConnectionsByPassive(peer_desc, local_desc) -``` - -被动端返回给主动端： - -```text -local_desc.local_nic_path -local_desc.peer_nic_path -local_desc.jetty_num -reply_msg -``` - -如果校验失败，`reply_msg` 会带错误信息，主动端拒绝继续建连。 - -### 7.3 Jetty import 与 bind - -主动端和被动端都会执行： - -```cpp -UrmaEndpoint::doSetupConnection(peer_eid, peer_jetty_num_list) -``` - -对每个 Jetty： - -```text -1. peer_eid 字符串转 urma_eid_t -2. 构造 urma_rjetty_t -3. urma_import_jetty() -4. urma_bind_jetty(local_jetty, imported_jetty) -5. imported_jetty_map_[local_jetty] = imported_jetty -``` - -全部 Jetty 绑定成功后： - -```cpp -status_ = CONNECTED; -``` - -之后 `submitPostSend()` 就可以把 `wr.tjetty` 设置为对应的 imported remote Jetty。 - -## 8. 完成轮询与状态查询 - -URMA 完成由 `UbWorkerPool` 后台线程处理。 - -### 8.1 worker 主循环 - -`UbWorkerPool::transferWorker()` 循环执行： - -```text -while running: - 如果没有未完成 slice: - 等待 cond_var - 否则: - performPostSend() - performPoll() -``` - -`performPostSend()` 负责把队列中的 slice 提交到 endpoint。 - -`performPoll()` 负责轮询 JFC： - -```cpp -context_.poll(kPollCount, cr, jfc_index); -``` - -### 8.2 UrmaContext::poll() - -底层调用： - -```cpp -urma_poll_jfc(jfc_list_[jfc_index].native, num_entries, cr); -``` - -每个 completion record 里通过 `user_ctx` 找回 slice： - -```cpp -auto slice = (Transport::Slice*)cr[i].user_ctx; -``` - -如果成功： - -```cpp -slice->markSuccess(); -``` - -如果失败，`poll()` 只记录错误；`performPoll()` 根据 slice 状态决定重试或最终失败。 - -### 8.3 markSuccess / markFailed 的效果 - -`Slice::markSuccess()` 会推进 task 级计数： - -```text -task.success_slice_count++ -task.transferred_bytes += slice.length -``` - -`Slice::markFailed()` 会推进： - -```text -task.failed_slice_count++ -``` - -用户侧查询： - -```cpp -TransferStatus status; -engine.getTransferStatus(batch, task_id, status); -``` - -`UbTransport::getTransferStatus()` 判断： - -```text -success_slice_count + failed_slice_count == slice_count -``` - -如果全部 slice 完成： - -- 有失败 slice：`FAILED` -- 全部成功：`COMPLETED` -- 否则：`WAITING` - -## 9. 失败重试流程 - -URMA 路径有两类失败处理。 - -### 9.1 post send 失败 - -`UrmaEndpoint::submitPostSend()` 调用： - -```cpp -urma_post_jetty_send_wr(jetty, wr_list, &bad_wr); -``` - -如果失败，会把 `bad_wr` 对应的 slice 放入 `failed_slice_list`，并回滚： - -```text -wr_depth_list_[jetty_index]-- -jfc_outstanding_-- -``` - -worker 随后调用： - -```cpp -redispatch(failed_slice_list, thread_id); -``` - -### 9.2 completion 失败 - -`performPoll()` 发现 slice 不是 SUCCESS： - -```text -slice->ub.retry_cnt++ - -如果 retry_cnt >= max_retry_cnt: - deleteEndpoint(peer_nic_path) - slice->markFailed() -否则: - 重新放回 collective_slice_queue_ -``` - -重新分发时会带着新的 `retry_cnt` 调用： - -```cpp -UbTransport::selectDevice(..., retry_cnt) -``` - -`retry_cnt` 会改变 topology 中的 device 选择，尽量避开刚刚失败的路径。 - -## 10. 注销内存与释放资源 - -用户注销内存： - -```cpp -engine.unregisterLocalMemory(addr);

-``` - -Transfer Engine 释放时，`UbTransport` 析构会： - -```text -removeSegmentDesc(local_server_name_) -清空 batch_desc_set_ -清空 context_list_ -``` - -`UrmaEndpoint::deconstruct()` 会： - -```text -urma_unbind_jetty() -urma_unimport_jetty() -urma_delete_jetty() -回收 outstanding 计数 -``` - -`UrmaContext::uninit()` 最终调用： - -```cpp -urma_uninit();

Mooncake 分布式元数据管理面轻量 Coordinator 架构设计

+ +

1. 设计摘要

+
+ 推荐方案： + 采用 Redis Cluster 风格的固定 slot 分片和客户端直连路由，同时引入一个不在前台请求路径上的轻量 Coordinator。 + Coordinator 只负责集群视图、slot 迁移计划、ownership version 与 fencing 发布、资源摘要聚合和后台任务预算调节；GetReplicaList、PutStart、PutEnd 等热路径请求仍由客户端直接访问 slot 所属 MasterGroup 的 current primary。 +
+ +

1.1 术语与层次

+ + + + + + + + + + +
术语本文中的唯一含义
MasterNode一个可寻址的 Master 进程实例；是部署、租约和故障域单位。
MasterGroup一个复制组；是日志提交、主备切换和一致性单位，包含一个 current primary 和若干 replica。
Slot由 key hash 得到的固定路由编号。
SlotGroup一组连续或离散 slot；是负载统计和组间迁移单位。
Slot owner拥有 SlotGroup 的 MasterGroup，而不是某个永久固定的 MasterNode。
Group primaryMasterGroup 当前接收强一致前台请求的 MasterNode，随 term 变化。
+

+ 下文若使用“Master 服务”，仅泛指 MasterNode 上运行的服务。路由、所有权或 failover 描述必须明确使用 + MasterGroup、Group primary 或 MasterNode，避免“Master Shard”同时指进程、复制组和 slot 分片。 +

+ +

1.2 Generation、Term、Revision 与 Fencing

+

+ 本设计不再把所有版本都称为 epoch，而是只区分三种语义：generation/term 是 fencing token， + 用于隔离旧 owner；revision 只用于快照发布、CAS 和增量 watch；sequence 只用于同一数据流内的样本排序。 + 只有 generation/term 会决定请求是否有权改变状态，revision 和 sequence 都不能授予写权限。 +

+ + 
+初始状态：SlotGroup S belongs to MasterGroup G1, assignment_generation = 7
+
+Client C1 cached: S -> G1, generation 7
+Coordinator migrates S: G1 -> G2, generation becomes 8
+
+C1 sends Put(key, owner=G1, assignment_generation=7)
+G1/G2 compares request generation with durable assignment:
+  7 < 8  -> reject STALE_ASSIGNMENT or MOVED(S, G2, 8)
+
+Without assignment_generation:
+  delayed C1 or old G1 might continue modifying S after cutover,
+  creating two owners and divergent object metadata.
+
+ +
+ Generation/term 的作用不是发现故障，而是隔离旧状态。 + lease/heartbeat 用于判断参与者可能失活；generation/term 用于在发生切换后证明请求仍属于当前一代。 + 仅检测到旧 primary 断连是不够的，因为它可能仍在运行，只是发生了网络分区。 +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
字段类别作用域何时递增防止的问题旧值处理
view_revisionRevision整个 ClusterView任意已发布集群视图发生变化增量更新乱序、旧 view 覆盖新 view客户端忽略旧 view；watch 缺口时重新读取全量 view
node_incarnation_idIncarnation UUID一个 node_id 的进程 incarnationMasterNode 每次启动生成新的 UUID重启前残留 lease/heartbeat 覆盖新进程状态拒绝旧 incarnation 的续租和上报
termFencing term一个 MasterGroup组内选出或授权新的 primary旧 primary 在网络分区后继续提交写返回 STALE_TERM 或 NOT_PRIMARY
assignment_generationFencing generation一个 SlotGroupSlotGroup 从一个 MasterGroup 迁到另一个 MasterGroup迁移后 source group 或旧客户端继续修改对象元数据返回 STALE_ASSIGNMENT 或 MOVED
control_generationFencing generation一个 Storage Client 的控制归属client control owner 从一个 MasterGroup 迁到另一个 group两个 group 同时接收 segment heartbeat、mount/unmount 或下发任务拒绝旧 heartbeat/控制写并返回新 control owner
segment_incarnationFencing incarnation一个物理 segment/allocator incarnationsegment 重新注册、重建 allocator 或不可兼容地 remount旧 reservation/descriptor 写入已经重建的物理空间reservation 失败，重新查询 segment 并分配
resource_revisionRevision一版聚合 ResourceViewCoordinator 发布新的资源摘要资源视图乱序覆盖忽略旧摘要；它不单独提供空间分配正确性
sample_seqSequence一个 segment 的遥测流同一 segment_incarnation 每发布一个样本递增延迟到达的容量/带宽样本覆盖新样本丢弃旧样本并结合 timestamp 判断 freshness
budget_revisionRevision一版 BackgroundBudgetCoordinator 调整后台任务预算旧预算重新放大迁移或 offload 流量忽略旧预算；当前预算过期则使用保守默认值
+ +

+ 四个 fencing scope 是 group term、slot assignment generation、client control generation + 和 segment incarnation。前三者可共享 FencingToken{scope_id, generation} 的实现；segment 使用 UUID incarnation token。 + 它们属于不同状态机，不能跨 scope 比较。 + revision/sequence 使用无符号 64 位单调计数器；incarnation 使用启动或重建时生成的 UUID，避免依赖旧进程持久化计数器。 +

+ 
+// 通用比较规则，不表示存在一个全局 generation。
+struct FencingToken {
+  string scope_id;
+  uint64_t generation;
+}
+
+SnapshotRevision = uint64_t;   // view/resource/budget，只用于排序、watch 和 CAS
+IncarnationId = UUID;          // node/segment，每次重启或重建生成新值
+StreamSequence = uint64_t;     // telemetry，在同一 incarnation 内单调递增
+
+ +

1.2.1 Term 为什么单独命名

+

+ term 本质上是 MasterGroup 的领导权 generation，但保留 term 这个名称是为了和 Raft 等复制协议一致。 + QUORUM 模式由组选举产生更高 term；ASYNC_STANDBY 模式由 Coordinator 在取得独占 fencing token 后授权更高 term。 + 无论采用哪种模式，数据写入权威方都必须检查 term。只把新 primary 地址写入服务发现，而不在提交点检查 term，不能防止双主。 +

+ +

1.2.2 Fencing 是什么

+

+ Fencing（隔离旧持有者）是“在最终写入点拒绝旧 token”的机制，generation/term/incarnation 是本文的 fencing token。 + 检查必须发生在真正改变状态的地方，例如 MasterGroup 日志提交、segment allocator reserve/free、HA Backend CAS， + 而不能只在客户端或入口 RPC 检查一次。否则请求通过检查后发生切主，延迟请求仍可能写入。 +

+ +

1.3 一致性与故障恢复基础概念

+ + + + + + + + + + + + + + + + + + + + + + + + + +
概念解释及本文中的用途
Lease有到期时间的临时所有权/存活声明，持有者必须续租。用于故障检测和资源自动回收，但不能代替 fencing。
CASCompare-And-Swap：仅当持久化值仍等于预期版本时才更新。用于保证两个 Coordinator 或迁移流程不能同时提交冲突 owner。
Quorum复制组的多数派。3 voter 中至少 2 个确认后提交，可容忍 1 个故障；失去多数派时宁可拒绝写，也不能产生两个合法 primary。
OpLog按顺序记录元数据状态变化的操作日志。replica 和迁移 target 先加载 snapshot，再 replay 后续 OpLog。
Snapshot某个一致性位置上的完整状态快照，用于避免从第一条 OpLog 开始恢复。snapshot 必须携带其对应的 log/commit position。
Replay lagtarget/replica 已应用位置与 source committed position 的差距。只有追到 cutover position 才能安全接管。
RPORecovery Point Objective，可接受的数据丢失范围。QUORUM 已提交写目标是 RPO=0；异步主备的 RPO 由尚未 replay 的日志决定。
RTORecovery Time Objective，从故障发生到恢复服务允许的时间；受故障检测、选主和 replay lag 影响。
Idempotency key同一逻辑操作重试时保持不变的 ID，使重复请求只产生一次状态变化，用于 reservation 和后台 Task。
ResourceView容量、带宽、IOPS 和健康状态的近实时只读快照，用于选候选；它可能过期，因此最终 reserve 仍需 allocator 原子确认。
Reservation带 TTL 的临时资源承诺。PutStart 预留、PutEnd 提交、PutRevoke/超时释放，以避免并发请求超卖。
Replica descriptor描述一个对象副本所在 segment、offset/length、介质类型和访问参数的元数据；它不是对象数据本身。
Failure domain共享故障风险的边界，例如进程、机器、机架或 AZ。副本跨域放置是为了避免一次故障同时损坏全部副本。
Locality调用方与 segment 之间的 NUMA、主机、机架、AZ 或网络 fabric 距离，用于估算访问时延和网络成本。
Rendezvous hash对“实体、候选节点”组合计算稳定分数并选最高者；候选集合变化时只移动较少实体。本文用于生成初始 control-owner 建议，最终映射仍由 Coordinator 显式提交。
Hard constraint不满足就绝不能选择的条件，例如容量不足、介质能力不符或副本处于同一故障域；与可权衡的软评分分开处理。
Dominant resource某候选节点上占用比例最高的资源维度。例如容量只占 20% 但带宽占 90%，其主导资源是带宽，不能因容量充足继续放置。
Hysteresis进入和退出某状态使用不同阈值或连续观测窗口，避免热点副本、预算和读路由在临界值附近频繁来回切换。
P99.999.9% 请求时延不超过的值，即每 1,000 个请求约有 1 个更慢；用于约束极端尾延迟，而不仅是平均性能。
MOVEDSlotGroup 已稳定归属于另一个 MasterGroup；客户端应更新本地长期路由并重试。
ASKSlotGroup 正在迁移，客户端仅对本次请求访问 importing group，不永久覆盖本地 owner。
+ +

1.4 一次 Put 请求如何使用这些版本号

+ 
+1. Client 从 ClusterView(view_revision=100) 得到：
+     slot 42 -> SlotGroup S7(assignment_generation=8)
+             -> MasterGroup G2(term=12)
+             -> primary endpoint B
+
+2. Client 向 B 发送 PutStart：
+     {group=G2, term=12, slot=42, assignment_generation=8, request_id=R}
+
+3. B 在写入 PROCESSING 元数据前检查：
+     a. 自己仍是 G2 term 12 的 primary；否则 NOT_PRIMARY/STALE_TERM
+     b. slot 42 仍属于 G2 且 generation=8；否则 MOVED/STALE_ASSIGNMENT
+     c. request_id R 是否已处理；若是则返回相同结果
+
+4. B 使用本地 ResourceView 选择目标存储节点，并从本组的 DelegatedExtentPool
+   分配已由后台租入的空间和资源预算。常态 Put 不同步访问 Coordinator 或远端 allocator。
+
+5. B 写入 PROCESSING 元数据，将变更异步复制给 standby，然后返回 replica descriptors。
+
+6. Client 写数据并发送 PutEnd(R)。B 再次检查 term、assignment_generation 和 request_id，
+   然后把对象从 PROCESSING 转为 COMPLETE，并异步复制该变更。
+
+

+ view_revision 只说明客户端使用哪一版路由快照，不授予写权限；真正保护写正确性的是对应作用域的 + term、assignment_generation、segment_incarnation 以及幂等 request_id。即使客户端 view 不是最新， + 服务端也能拒绝危险写，并通过错误码引导客户端刷新。 +

+ +
+ 和 Redis 的关系： + Redis Cluster 没有独立 Coordinator，slot ownership 和 failover 信息由节点 gossip 传播，reshard 通常由外部工具驱动。 + Mooncake 的不同点在于 Master 还承担物理空间管理、冷热分级、租约、client liveness 和后台迁移任务。 + 因此引入轻量 Coordinator 是为了管理 Mooncake 特有的全局控制问题，而不是替代 Redis Cluster 的去中心化热路径。 +
+ +
+ P99.9 原则： + Coordinator 不能成为 P99.9 热路径依赖。客户端在正常读写时不访问 Coordinator；Coordinator 故障只影响扩缩容、rebalance、跨组迁移、视图发布和预算调节，不影响已有稳定 group 的前台读写或 quorum 组内选主。 +
+ +

2. 设计目标与非目标

+

2.1 设计目标

+
    +
  • 将对象元数据按固定 slot 拆分到多个 MasterGroup，解除单 MasterNode 的 CPU、锁和 RPC 瓶颈。
    • +
  • 保持前台请求路径短：客户端计算 slot，直接访问对应 MasterGroup 的 current primary。
    • +
  • 在扩缩容、slot 迁移、failover、冷热分级、资源压力下保持 P99.9 时延稳定。
    • +
  • 用轻量 Coordinator 管理 slot view、资源摘要和后台预算，但不代理元数据请求。
    • +
  • 支持兼容式演进：单 Master 先暴露全量 slot view，再逐步引入多 Master 和迁移能力。
    • +
+ +

2.2 非目标

+
    +
  • 不把 Coordinator 做成所有元数据 RPC 的代理。
    • +
  • 不要求跨 slot Batch 操作具备全局原子性；默认提供逐 key 成功/失败结果。
    • +
  • 不要求第一阶段实现完整自动 rebalance；可以先由管理命令触发迁移计划。
    • +
  • 不把物理数据迁移放入 Master 进程内同步执行；Master 只负责元数据状态机和任务编排。
    • +
+ +

3.1 核心原则

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
原则含义
热路径去中心化客户端通过本地 slot map 直连 owner MasterGroup 的 current primary，不经过 Coordinator。
控制路径集中但轻量Coordinator 管理 view、跨组迁移、group placement、fencing 发布和预算，不保存每个对象的热路径状态。
对象状态单 owner同一个 key 的 Put/Get/Evict/Offload/Promotion 只由当前 slot owner MasterGroup 提交。
所有权带 fencing token组内 primary 用 term，slot 改属用 assignment_generation，segment 控制权改属用 control_generation；三者不能混用。
后台任务可退让迁移、snapshot、eviction、offload、promotion 必须受预算控制，P99.9 超阈值时自动降速。
+ +

4. 组件职责

+

4.1 Mooncake Client / SDK

+
    +
  • 维护本地 ClusterView 和 slot map 缓存。
    • +
  • 计算 slot = hash(tenant_id, key) % 16384。
    • +
  • 按 slot owner MasterGroup 解析 current primary endpoint 并直连。
    • +
  • 处理 MOVED、ASK、NOT_PRIMARY、STALE_TERM、TRYAGAIN、STALE_ASSIGNMENT。
    • +
  • 对 Batch 请求按 owner regroup，并按原始 key 顺序合并响应。
    • +
  • 设置 per-RPC deadline，避免单个 Master 慢请求拖垮 P99.9。
    • +
+ +

4.2 MasterGroup 与其 current primary

+
    +
  • MasterGroup 负责一组 SlotGroup 的对象元数据；current primary 对外服务，replica 按复制模式同步状态。
    • +
  • 执行对象生命周期状态机：PutStart、PutEnd、PutRevoke、Remove、Evict。
    • +
  • 维护对象租约、hard pin、soft pin 和访问热度统计。
    • +
  • 生成和消费对象级后台任务，例如 copy、move、offload、promotion。
    • +
  • 由 current primary 向 Coordinator 上报前台时延、队列深度、slot 负载、资源使用摘要和迁移状态。
    • +
  • 订阅 Coordinator 发布的 cluster view、resource view 和 background budget。
    • +
+ +

4.3 Lightweight Coordinator

+
    +
  • 维护 MasterNode incarnation、MasterGroup membership、slot ownership、assignment generation 和 view revision。
    • +
  • 生成扩缩容和 rebalance 计划。
    • +
  • 协调 slot group 迁移状态机，但不搬运前台请求。
    • +
  • 汇总 segment resource summary，发布近实时 ResourceView。
    • +
  • 根据 P99.9、队列深度、CPU、网络、replay lag 动态调节后台任务预算。
    • +
  • 观察组内选主结果并发布带 term 的新 primary endpoint；通过 HA Backend fencing 防止旧 primary 继续写。
    • +
+ +

4.4 HA Backend

+
    +
  • 持久化 cluster view、slot ownership、membership lease 和 coordinator lease。
    • +
  • 保存 MasterGroup 的 OpLog、snapshot catalog、commit position 或恢复指针。
    • +
  • 在 Coordinator 故障时支持新 Coordinator 接管。
    • +
+ +

4.5 Storage Client / Segment

+
    +
  • 向 Master 或 Resource Registry 上报 segment 容量、水位、健康状态。
    • +
  • 执行数据路径操作，例如 RDMA 写、SSD offload、本地 promotion、replica clear。
    • +
  • 通过 task heartbeat 获取 offload/promotion/copy/move 任务。
    • +
+ +

4.6 Segment 与 MasterGroup 的归属关系

+
+ 结论： + key 的 slot owner 和 segment 的 control owner 是两套独立映射。 + slot owner 管对象及其 replica 状态；segment control owner 管 segment 注册、心跳、健康状态和客户端级任务通道。 + 一个对象可以被放到任意健康 segment 上，因此对象的 slot owner 不要求等于该 segment 的 control owner。 +
+ +

+ 推荐按 client_id 而不是按 segment_id 分配 segment control owner：同一个 Storage Client + 注册的 MEMORY、LOCAL_DISK、NOF_SSD 等全部 segment 由同一个 control-owner MasterGroup 管理，heartbeat 发往该组 current primary。 + 这样 client liveness、一次 heartbeat 中携带的多个 segment 状态以及下发给该 client 的任务队列都落在同一处， + 不需要拆分一次 heartbeat。Coordinator 在 ClusterView 中持久化该映射；初次加入时可用 + rendezvous hash 选择 control-owner MasterGroup，并在负载不均衡时显式迁移，而不能由各 MasterNode 独立计算后直接生效。 +

+ + 
+对象控制面：hash(tenant_id, key) -> slot -> slot owner MasterGroup -> current primary
+Segment 控制面：client_id -> client control-owner MasterGroup -> current primary -> 全部 segments
+
+例：
+  Group G1 owns slots [0, 4095]       and controls Client X -> [Segment X.mem, X.ssd]
+  Group G2 owns slots [4096, 8191]    and controls Client Y -> [Segment Y.mem]
+  Group G3 owns slots [8192, 16383]   and controls Client Z -> [Segment Z.mem, Z.nof]
+
+  key K belongs to a slot owned by G2
+  K replicas may be placed on X.mem and Z.nof
+  G2 owns K metadata and decides create/remove/offload/promotion
+  G1 controls X.mem health; G3 controls Z.nof health
+  Storage Client X/Z remains the authority that atomically reserves/frees physical extents
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
状态或动作唯一写入者/权威方其他 Master 如何使用
key、replica descriptor、对象状态机key 的 slot owner MasterGroup非 owner 返回 MOVED，不得修改
client lease、segment mount/unmount、health、watermarkclient control-owner MasterGroup通过只读 ResourceView 获取摘要
物理 extent 的 reserve/freeStorage Client 的 allocator，使用 lease/CAS 和幂等 request_idslot owner 直接请求 allocator；control owner 不在每次 Put 的同步链路中
offload/promotion/copy/move 的对象决策对象 slot owner MasterGroup任务经 client control owner 的 heartbeat 通道投递，完成后回报 slot owner
segment control owner 映射Coordinator + HA Backend CAS所有 Master 订阅同一版本化映射
+ +

+ 因而“G1 管理 Segment X”只表示 G1 是 X 所属 client 的控制面 owner，并不表示只有 G1 的 slot + 才能在 X 上放 replica。所有 slot-owner group 都可依据 ResourceView 选择 X，但最终空间分配必须由 X 所在 + Storage Client 的 allocator 原子确认，避免多个 Master 根据过期容量摘要重复分配。 +

+ +

4.6.1 Owner 选择、故障与迁移规则

+
    +
  • 初始分配：Coordinator 对 client_id 和 ACTIVE MasterGroup 集合做 rendezvous hash，选择一个 control-owner group；组内 primary/replica 由该组成员关系决定。hash 可叠加连接数、segment 数和 heartbeat QPS 权重。
    • +
  • 稳定性：MasterNode 加入或退出时不自动重算全部 client；只有 Coordinator 生成并提交的新 group 映射才改变 owner，避免大规模心跳抖动。
    • +
  • 故障切换：current primary 失效后由组内复制协议选出新 primary 并递增 term；Coordinator 发布 endpoint。只有 client 从一个 control-owner group 迁到另一个 group 时才递增 control_generation。Storage Client 同时校验 term 和 control_generation，旧 primary 必须被 fencing。
    • +
  • 主动迁移：先让 target group 导入 client/segment 快照并接收增量状态，再递增 control_generation 切换 heartbeat，最后清理 source group；迁移期间对象 slot ownership 不变。
    • +
  • 故障域：同一 MasterGroup 的 replicas 尽量跨节点、机架或 AZ；同一 client 的 segment 不拆给多个 control-owner group，除非未来 heartbeat 协议支持按 segment 独立分流。
    • +
+ +
+ 不要混淆三种变化： + MasterGroup 组内切主只提升 term；SlotGroup 跨组迁移改变对象元数据归属并提升 assignment_generation； + client control owner 跨组迁移改变 segment 控制归属并提升 control_generation。任何一种变化都不应隐式触发另外两种。 +
+ +

4.6.2 跨组任务投递

+

+ 当对象 slot owner 与目标 segment control owner 不同，不能依赖两个 group 的内存队列或分布式事务。 + 对象 owner 先在本组 OpLog 中提交 TaskIntent，再以至少一次语义投递到 control-owner group；后者通过 + Storage Client heartbeat 下发。完成通知可重复发送，由对象 owner 根据 task_id 幂等提交最终 replica 状态。 +

+ 
+TaskEnvelope {
+  UUID task_id;
+  string object_owner_group_id;
+  uint64_t object_group_term;
+  uint32_t slot_id;
+  uint64_t assignment_generation;
+  string client_control_group_id;
+  uint64_t control_generation;
+  UUID target_segment_id;
+  TaskType type;
+}
+
+

+ 任一 fencing generation/term 不匹配时不得盲目执行：投递方刷新 ClusterView 后重新路由，执行方使用 + task_id 去重。这样组内切主、SlotGroup 迁移或 client control owner 迁移都不会造成任务丢失或重复修改对象状态。 +

+ +

4.7 多 Master 的分组：MasterGroup 与 MasterNode

+
+ 推荐模型： + 用 MasterGroup（也可称 ReplicaSet）表达主备复制关系，用不同 MasterGroup 之间的 slot + 分配表达 shard 分担关系。MasterNode 只是进程/机器实例，不应被永久标记成全局 primary、standby 或 shard。 +
+ + 
+                         Cluster
+                            |
+          +-----------------+-----------------+
+          |                                   |
+    MasterGroup G1                       MasterGroup G2
+    owns slot groups 0..3                owns slot groups 4..7
+    (shard relation with G2)             (shard relation with G1)
+          |                                   |
+    primary: Master A                    primary: Master C
+    standby: Master B                    standby: Master D
+    (A/B are replication peers)          (C/D are replication peers)
+
+Client route:
+  key -> slot -> slot_group -> master_group -> current primary endpoint
+
+ +

+ 因此，“A 和 B 是主备”表示它们是同一个 MasterGroup 的复制成员；“A 和 C 分担 shard”更准确地说是 + A 所在的 G1 与 C 所在的 G2 分别拥有不同 slot group。主备关系发生在组内，分片关系发生在组间， + 两者不应使用同一个 role 字段表达。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
抽象职责所有权/版本
MasterNode描述进程地址、故障域、容量、存活租约；可承载一个或多个 group replicanode_id + node_incarnation_id
MasterGroup对象元数据的一致性与故障切换单元，包含一个 primary 和若干 standbygroup_id + term
GroupMember描述某个 node 在某个 group 内的 PRIMARY、VOTER、LEARNER 等角色角色只在 group 内有效
SlotGroupAssignment把一段 slot 映射到一个 MasterGroup；扩缩容时迁移该映射及其状态assignment_generation
+ +

4.7.1 两种部署方式

+

方式一：节点独占 group，建议作为第一阶段。

+ 
+G1 = {A primary, B standby}
+G2 = {C primary, D standby}
+
+
    +
  • 关系直观，故障和容量边界容易分析，运维简单。
    • +
  • standby 正常情况下资源利用率较低，可提供只读诊断，但不应承接强一致前台写。
    • +
  • 两副本只能实现异步或同步主备，无法在网络分区下形成安全多数派；需要 quorum 强一致时，每组至少放置 3 个跨故障域 voter。
    • +
+ +

方式二：一个节点承载多个 group replica，用于提高利用率。

+ 
+G1 = {A primary, B standby, C standby}
+G2 = {B primary, C standby, A standby}
+G3 = {C primary, A standby, B standby}
+
+
    +
  • A、B、C 都承担一部分 primary shard，同时又互为其他 group 的 replica；“standby”是非 primary replica 的统称，QUORUM 模式对应 VOTER，ASYNC_STANDBY 模式对应 FOLLOWER。
    • +
  • 调度必须限制同一 node 的 primary 数、总 QPS、metadata bytes、replay 带宽和故障恢复负载。
    • +
  • 同一 group 的两个 replica 不能落在同一进程或同一故障域；否则节点或机架故障会同时丢失主备。
    • +
  • 一个 node 故障后，不能让其所有 standby 同时提升到同一个剩余 node，需要预先校验 failover capacity。
    • +
+ +

4.7.2 分组与迁移规则

+
    +
  • 组内切主：只改变 MasterGroup.term 和 primary member，不改变该组拥有的 slot；客户端刷新 endpoint 即可。
    • +
  • 组间迁移：把 SlotGroup 从 source MasterGroup 复制到 target MasterGroup，完成 snapshot/replay 后递增 assignment_generation 并切换归属。
    • +
  • 成员变更：采用 learner 加入、追平、转 voter、移除旧 member 的联合配置流程，不能直接覆盖成员列表。
    • +
  • 分组粒度：MasterGroup 数量应多于物理节点数，才能细粒度均衡；但每组都有 OpLog、snapshot 和 heartbeat 成本，应使用固定数量的虚拟 group，而不是每个 slot 一个复制组。
    • +
  • Coordinator 边界：Coordinator 决定 group membership 和 slot-to-group assignment；组内复制协议决定日志提交和 primary，不让 Coordinator 进入每次元数据写的提交路径。
    • +
  • Segment 控制归属：ClientControlOwner 也指向 MasterGroup，而不是裸 node；heartbeat 访问该组当前 primary，组内切主不改变 client 的逻辑归属。
    • +
+ +
+ 关键约束： + 如果没有真正的组内复制协议和提交法定人数，只能称为 primary/standby snapshot failover，不能宣称强一致 HA。 + 此时 primary 故障可能丢失尚未同步的 OpLog，ClusterView 必须暴露相应的 RPO 状态。 +
+ +

5. 数据模型

+

5.1 ClusterView

+ 
+struct ClusterView {
+  string cluster_id;
+  uint64_t view_revision;
+  uint32_t slot_count;          // default: 16384
+  vector<MasterNode> nodes;
+  vector<MasterGroup> master_groups;
+  vector<SlotGroupOwner> slot_groups;
+  vector<ClientControlOwner> client_control_owners;
+}
+
+struct MasterNode {
+  string node_id;
+  string rpc_address;
+  NodeStatus status;
+  FailureDomain failure_domain;
+  UUID node_incarnation_id;

+}
+
+struct GroupMember {
+  string node_id;
+  GroupRole role;               // PRIMARY / VOTER / FOLLOWER / LEARNER
+  CommitPosition replayed;
+}
+
+struct SlotGroupOwner {
+  uint32_t slot_group_id;
+  uint32_t slot_begin;
+  uint32_t slot_end;
+  string owner_master_group_id;
+  uint64_t assignment_generation;
+  SlotGroupState state;
+}
+
+struct ClientControlOwner {
+  UUID client_id;               // applies to all segments of this client
+  string owner_master_group_id;
+  uint64_t control_generation;  // independent from slot assignment
+  ControlOwnerState state;
+}
+
+ +

5.2 ResourceView

+ 
+struct ResourceView {
+  uint64_t resource_revision;
+  vector<SegmentResource> segments;
+  ClusterPressure pressure;
+}
+
+struct SegmentResource {
+  UUID segment_id;
+  UUID client_id;
+  uint64_t control_generation;
+  UUID segment_incarnation;
+  string segment_name;
+  ReplicaType type;             // MEMORY / LOCAL_DISK / NOF_SSD / CXL
+  ResourceCapability capability;
+  ResourceTelemetry telemetry;
+  FailureDomain failure_domain;
+  NetworkLocality locality;
+  SegmentHealth health;
+}
+
+ +

5.3 多维资源、工作负载与放置抽象

+
+ 设计原则： + 不再用单一 used_bytes / capacity_bytes 判断节点优劣，而把“节点能提供什么”、 + “对象需要什么”和“当前还承诺了多少资源”分开建模。容量大但带宽小的 segment 可承载冷数据， + 容量小但带宽大的 segment 可承载热点副本；同一对象的持久放置与实时读流量也可以由不同策略处理。 +
+ +

建议增加以下六类稳定抽象：

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
抽象回答的问题更新频率与归属
ResourceCapabilitysegment 的容量、顺序/随机读写带宽、IOPS、基础时延、并发度和介质能力上限慢变化；注册或基准测试时由 Storage Client 上报
ResourceTelemetry当前空闲容量、可用带宽、队列深度、P99 时延、错误率和热度快变化；control owner 聚合后发布带时间戳的摘要
FailureDomain / NetworkLocality节点、机架、AZ、NUMA、RDMA fabric 与访问方之间的故障隔离和网络代价低频变化；Coordinator 维护
WorkloadIntent对象预期大小、读写比、目标吞吐/P99、热度、生命周期、持久性和副本约束写入时显式提供，缺省值由历史观测推断
ResourceReservation已被并发 Put 或流量调度承诺、但尚未反映到 telemetry 的 bytes、bandwidth 和 IOPS实时；allocator/traffic admission 以 lease + segment incarnation 管理
PlacementPolicy + ScoreBreakdown如何执行硬约束过滤、软目标打分，以及为什么选择某个 segment版本化策略；Master 本地执行并记录可解释结果
+ + 
+struct ResourceVector {
+  uint64_t capacity_bytes;

+  string policy_version;
+}
+
+ +

5.3.1 放置和读路由必须解耦

+
    +
  • Replica Placement：决定数据存在哪些 segment，主要优化容量、持久性、写入代价和故障域。
    • +
  • Replica Read Selection：在已有 replica 中按实时带宽、队列、时延和调用方 locality 选择读源；不因为一次流量变化立即搬数据。
    • +
  • Tiering / Rebalance：根据较长时间窗口的热度和资源价格决定复制、迁移、offload 或 promotion，带 hysteresis 和冷却时间。
    • +
+

+ 例如，大容量低带宽节点可保存完整冷副本，小容量高带宽节点只保存工作集热点副本；读请求优先访问高带宽副本， + 高带宽层容量不足时淘汰热点副本不会删除低带宽层的持久副本。这样“容量归属”和“流量归属”不再被一个 placement 决策绑死。 +

+ +

5.3.2 可演进的算法接口

+ 
+PlacementResult Place(PlacementContext ctx) {
+  candidates = FilterByHardConstraints(
+      ctx.resource_view, ctx.intent, ctx.excluded_failure_domains);
+
+  candidates = CheckMultiResourceFeasibility(
+      candidates, capability - telemetry.used - telemetry.reserved);
+
+  ranked = policy.Score(candidates, ctx.intent, ctx.policy_version);
+  reservation = TryReserve(ranked, bytes + bandwidth + iops, bounded_attempts);
+
+  return {reservation, ranked.winner.score_breakdown};
+}
+
+
    +
  • 硬约束和软评分分离；容量不足、目标 P99 不满足、故障域冲突必须先过滤，不能靠低分表达。
    • +
  • 采用归一化 headroom 或 Dominant Resource Fairness 思路检查多维可行性，避免容量充足却把带宽耗尽。
    • +
  • PlacementPolicy 是版本化、无状态接口；后续可从加权打分演进为 bin-packing、min-cost flow 或学习型策略，而不改变 Put 状态机。
    • +
  • 策略输入只使用版本化快照，输出保存 policy_version 和 ScoreBreakdown，便于回放、灰度和比较新旧算法。
    • +
  • 在线请求只对 Top-K 候选做有界 reserve 尝试；复杂的全局优化在 Coordinator 后台生成 policy 参数或迁移计划，不能进入 Put 热路径。
    • +
+ +

5.3.3 指标语义要求

+
+ 避免错误建模： + 带宽不能只保存一个静态数值。至少区分读/写、可持续能力/当前使用量/已预留量，并按对象大小桶记录有效吞吐和时延； + 否则 100 Gbit/s 网卡、SSD 顺序吞吐和 4 KiB 随机访问会被错误地视为同一种资源。 +
+ +

5.4 BackgroundBudget

+ 
+struct BackgroundBudget {
+  uint64_t budget_revision;
+  uint32_t migration_max_inflight_groups;
+  uint32_t migration_qps_budget;
+  uint64_t snapshot_bytes_per_sec;
+  uint32_t eviction_keys_per_round;
+  uint32_t offload_tasks_per_heartbeat;
+  uint32_t promotion_tasks_per_heartbeat;
+}
+
+ +

6. 热路径流程分析

+

6.1 GetReplicaList

+ 
+Client
+  -> calculate slot(key)
+  -> find owner from local ClusterView
+  -> RPC GetReplicaList(key, tenant_id, master_group_id, group_term,
+                        slot_id, assignment_generation)
+
+Owner MasterGroup current primary
+  -> validate master_group_id, term, slot ownership and assignment_generation
+  -> lookup object metadata in local slot group
+  -> refresh lease / hotness counter
+  -> rank readable replicas by current latency / bandwidth / caller locality
+  -> if promotion-on-hit eligible: enqueue promotion task only
+  -> return replica list
+
+Client
+  -> if OK: use replica descriptors for data path
+  -> if MOVED/STALE_ASSIGNMENT: refresh slot map and retry
+  -> if TRYAGAIN: short backoff within request deadline
+
+ +

+ P99.9 控制点：读路径只访问一个 MasterGroup primary；promotion 不在前台执行；slot view 或 group term 过期通过重定向快速修正；RPC 有 deadline。 +

+ +

6.2 PutStart / PutEnd

+ 
+PutStart:
+Client -> owner MasterGroup current primary
+  -> validate group term and assignment generation
+  -> build WorkloadIntent from request policy and observed history
+  -> filter hard constraints and score candidates from local ResourceView
+  -> allocate from the local DelegatedExtentPool
+  -> write object PROCESSING metadata
+  -> enqueue asynchronous standby replication
+  -> return replica descriptors
+
+Data Path:
+Client writes object data to selected replicas
+
+PutEnd:
+Client -> owner MasterGroup current primary
+  -> validate group term and assignment generation
+  -> transition PROCESSING -> COMPLETE
+  -> enqueue asynchronous standby replication
+  -> optionally enqueue offload task
+  -> return OK
+
+ +

+ P99.9 控制点：PutStart 不向 Coordinator 或远端空间分配服务同步请求资源；ResourceView 和 DelegatedExtentPool 都在本地。 + 本地 extent 不足时快速失败并触发后台补充，禁止把远端 refill 或长时间候选扫描退化到当前请求中。 +

+ +

6.3 Batch 请求

+ 
+Client input keys: [k1, k2, k3, k4, k5]
+
+Regroup by owner:
+  Master A: [k1, k4]
+  Master B: [k2, k5]
+  Master C: [k3]
+
+Parallel RPC:
+  send sub-batches concurrently with per-shard deadline
+
+Merge:
+  output results in original key order
+
+ +

+ P99.9 控制点：子批次并行，单个慢 shard 不阻塞其他 shard 的结果；业务可选择 fail-fast、partial success 或 bounded retry。 +

+ +

6.4 时序图与当前 Mooncake 对比

+

+ 本节只统计正常稳定状态，不把首次建连、ClusterView watch、MOVED/STALE_TERM 重试和故障恢复计入常态热路径。 + 当前实现以代码中的单个全局 MasterService 为基线：客户端 Get 调用一次 + GetReplicaList；Put 调用 PutStart、执行数据传输、再调用 PutEnd； + segment allocator 由 Master 进程内的 segment_manager_ 访问。当前 1024 个 metadata shard 是进程内锁分片， + 不是分布式 MasterGroup。对应代码入口为 client_service.cpp::Get/Put、 + master_client.cpp::GetReplicaList/PutStart/PutEnd 和 master_service.cpp::GetReplicaList/PutStart/PutEnd。 + 图中的当前基线是默认非 HA 模式；当前 HA 仍是单个 active Master，客户端 RPC 形状不变，leader watch 在后台执行。 + 若某种 HA 配置把 OpLog 外部持久化同步放入请求路径，应把该耗时作为单独基线实测，不能与默认模式混合比较。 +

+

+ 本节时序图使用 Mermaid 11 sequenceDiagram 绘制；HTML 通过官方推荐的 ESM 方式从 jsDelivr 加载。 + 无网络环境仍会保留 Mermaid 源码，可在文档构建阶段改为 vendored Mermaid 或预渲染 SVG。 +

+ +

+
+ +

+ 正常 Get 的通信次数与当前实现相同，新增 slot hash、view lookup、term/generation 比较均为本地 CPU 操作。 + 但当前 Get 会刷新对象 read lease；如果新设计把每次 lease/hotness 更新同步复制到 quorum，Get 将额外增加一个 group commit RTT， + 形成明显劣化。推荐把访问热度和 lease heartbeat 做本地聚合、异步批量复制，并规定新 primary 在提升后至少一个 + max_read_lease_ttl 窗口内禁止回收旧 replica。这样 failover 期间保守占用空间，但正常 Get 不增加网络轮次。 +

6.4.5 Put：新设计快路径

+

+ Put 只采用这一条前台路径。为避免每次 PutStart 同步访问空间分配服务，增加 DelegatedExtentLease：Storage Client allocator + 预先把互不重叠的 extent range、bytes/bandwidth/IOPS budget 租给 MasterGroup。Group primary 在租约范围内本地切分， + 后台低水位时批量续租。lease 必须携带 segment_incarnation + control_generation + owner_group_id + group_term + expire_at， + Storage Client 不得把同一 extent 同时租给两个 group。 +

+

+    end
+    Note over Client,Primary: Same synchronous metadata RPC count as current = 2
+    Note over Primary,Allocator: Normal PutStart allocator RPC = 0, synchronous replication RTT = 0
+
+

+ 该快路径在同步通信形状上与当前实现一致：2 次 metadata RPC、按配置副本数执行数据写、0 次逐对象 allocator RPC、0 次同步复制 RTT。 + 代价是 PROCESSING/COMPLETE 在 follower 确认前已经向客户端返回，因此 ASYNC_STANDBY 存在非零 RPO。 + 因而本设计的 Put 语义必须明确公布这一 RPO，不能把异步复制描述为 RPO=0 的强一致提交。 +

+

+ primary 切换后，新 term 不得继续本地切分旧 term 的 delegated range；旧 range 进入 quarantine，等待 lease TTL + 到期或 allocator 明确回收，新 primary 获取新 range。这样即使旧 primary 暂时仍可访问数据网络，也只可能在隔离范围内产生孤儿写， + 不会与新 primary 重复分配同一 extent。该策略用临时容量占用换取正常 PutStart 的零 allocator RTT。 +

+ +

+            G3-->>Client: results 3
+        end
+        Client->>Client: merge in original key order
+    end
+
+

+ 当前跨任意 key 的 Batch 只发 1 个 Master RPC；新设计涉及 G 个 owner 时发送 G 个并行 RPC。 + 消息数从 2 个单向消息增加为 2G，但理想情况下仍是 1 个串行网络轮次。它提高总吞吐和故障隔离， + 但整批完成时延变为所有 sub-batch 的最大值；因此必须支持 per-group deadline、partial result，以及限制最大并发 group 数。 +

+ +

6.4.7 Storage heartbeat 与后台任务

+        Control-)Object: idempotent completion batch
+    end
+    Note over Storage,Control: Per heartbeat RPC count unchanged, cross-group messages are asynchronous
+
+

+ 每类 heartbeat 的前台 RPC 次数不变，Coordinator 不参与。新增的跨组 TaskEnvelope/Completion 是后台批量通信， + 不进入应用 Get/Put 的同步关键路径；如果实现成每对象同步转发，则会放大 RPC，违反本设计。 +

+ +

6.4.8 通信次数与性能结论

稳定状态 CoordinatorHA client watch backend周期/watch 更新 ClusterView 和 budget0（不在请求路径）不影响单请求时延，但增加低频控制面流量。
+ +
+ 结论： + Put 采用 delegated extent 和 ASYNC replication 的唯一快路径，并配合并行 sub-batch、异步 lease/hotness 和后台任务批量化后， + Get、单 key Put 和 heartbeat 的同步 RPC/网络轮次可以与当前实现保持一致，因此设计目标可以设为“基本不劣化”。 + 该 Put 路径采用 ASYNC_STANDBY，允许非零 RPO；接口、监控和验收结果必须明确披露这一语义。 +
+ +

6.4.9 必须通过的性能验收

+
    +
  • 相同硬件、对象大小、replica 数和并发度下，对比当前单 Master 与采用 ASYNC_STANDBY 的新设计快路径。
    • +
  • 分别测试 4 KiB、64 KiB、1 MiB、16 MiB；报告 metadata-only 与 end-to-end 的吞吐、P50、P99、P99.9。
    • +
  • Get：单副本 MasterGroup 相比当前实现在无 CPU 饱和时 P99.9 增幅目标不超过 5%；超出则必须给出 route/serialization/queue breakdown。
    • +
  • Put：ASYNC + delegated extent 快路径相比当前实现在无 CPU 饱和时 metadata P99.9 增幅目标不超过 5%；分别报告 local allocation、async enqueue 和 data transfer。
    • +
  • Batch：固定总 key 数，扫描 G=1/2/4/8/16；报告消息数、最慢 group latency 和 partial-result 时间。
    • +
  • 验证 Coordinator 停止 60 秒时稳定 Get/Put 的 RPC 数和时延分布不发生变化。
    • +
  • 验证 lease/hotness 更新、TaskEnvelope 和 ResourceView 上报不出现在应用请求 trace 的同步 critical path。
    • +
+ +

7. 控制路径流程分析

+

7.1 MasterNode 加入集群

+ 
+1. New MasterNode starts with node_id and rpc_address.
+2. It registers membership lease in HA Backend.
+3. Coordinator observes the new node and marks it JOINING.
+4. Coordinator publishes a new ClusterView including the node but assigns no MasterGroup replica yet.
+5. After health check and warmup pass, node becomes ACTIVE.
+6. Coordinator adds it to selected MasterGroups as LEARNER.
+7. After snapshot/replay catches up, each group promotes the learner to VOTER or PRIMARY candidate.
+8. Coordinator may then generate a plan to move SlotGroups between MasterGroups.
+
+ +

+ 加入过程不影响已有 slot 的前台读写。只有当 slot group 迁移进入 cutover 时，相关 slot 的客户端会看到短暂 MOVED/ASK。 +

+ +

7.2 MasterNode 优雅下线

+ 
+1. Operator marks MasterNode DRAINING.
+2. Coordinator stops placing new group replicas or primaries on this node.
+3. For every affected MasterGroup, add and catch up a replacement learner.
+4. Transfer primary leadership away, then remove this node from group membership.
+5. Only if group-level load remains imbalanced, move SlotGroups between groups in small batches.
+6. When the node carries no group replica, mark it INACTIVE and stop the process.
+
+ +

+ P99.9 控制点：drain 以小批量迁移执行；当前台 P99.9 超阈值时迁移自动暂停；不做全节点一次性冻结。 +

+ +

7.3 扩容 Rebalance

+ 
+1. Coordinator collects load:
+   - per slot group QPS
+   - key count / metadata bytes
+   - foreground P99.9
+   - migration backlog
+   - resource pressure
+
+2. Coordinator selects candidate slot groups:
+   - avoid hottest slot groups first
+   - prefer large imbalance but low active QPS groups
+   - limit concurrent groups
+
+3. Coordinator starts migration:
+   source -> snapshot copy -> incremental replay -> short cutover -> cleanup
+
+4. Coordinator observes P99.9 guard:
+   if P99.9 or queue depth exceeds threshold: reduce budget or pause migration
+
+5. Repeat until target balance reached.
+
+ +

7.4 缩容 Rebalance

+ 
+1. Operator marks nodes to remove as DRAINING.
+2. Coordinator computes target placement excluding DRAINING nodes.
+3. Slot groups migrate away in priority order:
+   - cold / low QPS slot groups first
+   - hot slot groups during low-traffic windows
+4. If remaining capacity is insufficient, Coordinator rejects shrink plan.
+5. After migration completes, DRAINING node is removed.
+
+ +

+ 缩容比扩容更容易造成尾延迟，因为目标节点承接更多负载。必须先做容量校验和 P99.9 预算校验，不能只看 slot 数是否均衡。 +

+ +

7.5 Slot Group 迁移

+ 
+Plan:
+  Coordinator chooses source MasterGroup, target MasterGroup, slot_group_id, migration_budget.
+
+Prepare:
+  Target group primary creates empty slot group in IMPORTING state.
+  Source group primary marks slot group MIGRATING_SOURCE and records start_oplog_offset.
+
+Snapshot Copy:
+  Source scans metadata in bounded batches.
+  Target group replicates and commits imported batches but does not serve normal requests yet.
+
+Incremental Replay:
+  Source streams OpLog after start_oplog_offset.
+  Target group commits replay and reports committed replay_lag.
+
+Cutover:
+  Source briefly blocks writes for the slot group.
+  Source commits the final OpLog tail and emits a cutover position.
+  Target proves that the cutover position is committed by its replication mode.
+  Coordinator CAS-updates owner_master_group_id and increments assignment_generation with a fencing token.
+  Source group returns MOVED for new requests.
+  Target group serves requests with the new assignment generation.
+
+Cleanup:
+  Source keeps tombstone for late requests, then releases old metadata.
+
+ +

7.6 MasterNode 故障与 MasterGroup Failover

+ 
+1. HA Backend lease expires or health checks fail.
+2. Coordinator marks node SUSPECT, then UNAVAILABLE after quorum/lease confirmation.
+3. QUORUM group elects a replica holding the committed prefix; ASYNC_STANDBY group requires Coordinator-authorized promotion and reports possible RPO loss.
+4. New primary proves its commit/replay position and obtains a higher group term/fencing token.
+5. Coordinator publishes the new primary endpoint and term; slot owner and assignment_generation remain unchanged.
+6. Clients receive NOT_PRIMARY/STALE_TERM or refresh view after RPC deadline.
+7. New primary serves foreground traffic; groups without quorum remain unavailable instead of accepting split-brain writes.
+
+ +

+ P99.9 控制点：故障检测不等待长 RPC；客户端使用短 deadline；failover 以 MasterGroup 为粒度并可并行；replica 持续 replay，避免切换后大规模恢复。组内切主不递增 assignment_generation，只有 SlotGroup 改属另一个 MasterGroup 时才递增。 +

+ +

7.7 Coordinator 故障

+ 
+1. Active Coordinator lease expires in HA Backend.
+2. Standby Coordinator competes for coordinator lease.
+3. New Coordinator reads persisted ClusterView and migration states.
+4. It reconciles Master reports.
+5. Incomplete migration is either resumed or rolled back.
+6. Foreground metadata requests continue using last stable ClusterView.
+
+ +

+ Coordinator 故障不应影响稳定 slot 的读写，也不阻止具备 quorum 的 MasterGroup 完成组内选主。受影响的是新的扩缩容计划、跨组迁移、primary endpoint 发布和后台预算更新。 +

+ +

7.8 资源压力与 Admission Control

+ 
+1. Storage clients report segment usage and health.
+2. MasterGroup primaries report allocation failures and queue depth.
+3. Coordinator computes cluster pressure level.
+4. Coordinator publishes ResourceView and BackgroundBudget.
+5. MasterGroup primaries adjust placement, eviction/offload speed, and admission policy.
+6. If resources remain insufficient, PutStart fails fast with a precise error.
+
+ +

+ P99.9 控制点：资源不足时不能让 PutStart 在 Master 内反复扫描和等待；应快速失败、降级 replica 数，或交给上层重试。 +

+ +

7.9 冷热分级任务

+ 
+Get path:
+  GetReplicaList observes LOCAL_DISK-only hot key
+  -> enqueue promotion task
+  -> return current readable replica immediately
+
+Background path:
+  Storage client heartbeat pulls promotion/offload tasks
+  -> executes data movement
+  -> NotifyPromotionSuccess / NotifyOffloadSuccess
+  -> slot owner commits metadata transition
+
+ +

+ P99.9 控制点：冷热任务必须异步化；前台读不等待 promotion 完成；Coordinator 只调节任务预算，不参与单对象决策。 +

+ +

8. P99.9 稳定性设计

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
设计点要求原因
Coordinator 非热路径正常 Get/Put 不访问 Coordinator避免把 Coordinator 变成新的尾延迟来源
前台 RPC 优先级MasterNode 按 group 区分 foreground queue 和 background queue迁移和扫描不能挤占客户请求
短锁和分片锁对象状态锁限定在 slot group 或 key 粒度避免全 shard 锁导致 P99.9 抖动
迁移预算限制同时迁移 slot group、snapshot 带宽和 replay QPS扩缩容期间稳定前台时延
快速失败资源不足、fencing token 过期、owner 错误时快速返回明确错误避免请求排队等待不可满足条件
客户端 deadline每个 Master RPC 设置 deadline 和 bounded retry控制跨 shard Batch 的尾部等待
自动保护闭环当 P99.9 超阈值时自动降低后台预算把客户时延优先级置于扩缩容速度之上

+
+MasterGroup owns:

9.2 开发视图

+

+ 开发视图描述代码模块拆分建议。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
模块职责可能落点
ClusterViewClient客户端获取、缓存、刷新 slot mapmooncake-store/include/master_client.h 附近新增路由层
ShardRouter计算 slot，处理 MOVED/ASK，Batch regroupMasterClient 内部组件
MasterNodeService承载一个或多个 MasterGroup replica 的服务进程从现有 MasterService 演进
SlotOwnershipManager校验 master_group_id、term、slot ownership 和 assignment_generationMasterNode 内部
CoordinatorService集群视图、跨组迁移、fencing 发布、预算控制新增 coordinator 模块
ResourceRegistry汇总 segment 容量、水位、健康状态Coordinator 子模块或独立库
MigrationManagerslot group snapshot、replay、cutoverCoordinator + source/target MasterGroup 协作

+ +

9.3 进程视图

+

+ 进程视图描述运行时并发关系和通信路径。 +

+ 
+Client Process
+  - foreground application threads
+  - MasterClient routing cache
+  - RPC pools per MasterGroup primary
+
+MasterNode Process
+  - foreground RPC workers
+  - background task workers
+  - one or more MasterGroup replicas
+  - per-group slot state store
+  - per-group OpLog append/replay worker
+  - metrics reporter
+  - migration sender/receiver
+
+Coordinator Process
+  - membership watcher
+  - cluster view publisher
+  - migration planner
+  - group placement / fencing publisher
+  - resource aggregator
+  - latency guard loop
+
+HA Backend
+  - lease/session service
+  - durable key-value records
+  - watch/notify stream
+
+ +

+ 前台通信路径：Client -> owner MasterGroup current primary。控制通信路径：MasterNode -> Coordinator -> HA Backend，或 Coordinator -> MasterNode。 + 两者必须使用独立 RPC 队列或至少独立优先级，防止控制面流量影响客户请求。 +

+ +

9.4 物理视图

+

+ 物理视图描述部署拓扑。 +

+ 
+Rack / AZ A:
+  MasterNode A: G1 primary, G2 voter, G3 voter
+  Storage Clients
+
+Rack / AZ B:
+  MasterNode B: G2 primary, G1 voter, G3 voter
+  Storage Clients
+
+Rack / AZ C:
+  MasterNode C: G3 primary, G1 voter, G2 voter
+  Storage Clients
+
+Coordinator:
+  active + standby deployment
+  backed by HA Backend lease
+
+HA Backend:
+  odd-number quorum deployment if using etcd-like backend
+
+ +

+ 同一 MasterGroup 的 replicas 应跨故障域部署，并为任一节点故障后的 primary 提升预留容量。Coordinator active/standby 也应跨节点部署，但 Coordinator 不承载热路径，因此其资源规格可以小于 MasterNode。 +

+ +

9.5 场景视图

+

+ 场景视图对应架构的 +1，用关键用例验证其他四个视图是否闭合。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
场景参与组件关键判断
正常 GetClient、owner MasterGroup primary不访问 Coordinator；单 group primary 完成并按复制模式提交。
正常 PutClient、owner MasterGroup primary、Storage ClientMaster 使用本地 ResourceView；不阻塞等待 Coordinator。
扩容Coordinator、Source Group、Target Group、Client迁移按预算执行；cutover 通过 assignment generation 和 MOVED 完成。
缩容Coordinator、Draining MasterNode、affected MasterGroups先容量校验，再低 QPS slot group 优先迁移。
MasterNode 故障affected MasterGroups、Coordinator、HA Backend、Client各组独立提升 term 和 primary；slot owner/assignment_generation 不变。
Coordinator 故障HA Backend、Standby Coordinator、MasterGroups稳定 slot 前台读写继续；迁移编排暂停后恢复。
P99.9 抖动MasterGroups、CoordinatorLatencyGuard 降低后台任务预算，必要时暂停迁移。

F04
客户端 Group 路由		实现 key -> slot -> SlotGroup -> MasterGroup -> primary endpoint，校验 group term 和 assignment_generation。使用 fake view 将全量 slot 路由到预期 endpoint；收到 NOT_PRIMARY、STALE_TERM、MOVED 后在 bounded retry 内刷新并成功；Coordinator 不出现在正常 Get/Put 调用链。
F05
Batch Regroup		按 MasterGroup 并行拆分 Batch，并按输入顺序合并逐 key 结果。混合至少 3 个 group、重复 key 和部分失败时，输出顺序及错误一一对应；一个 group 超时不取消已完成 group；总等待不超过配置 deadline。
F06
MasterNode Membership		实现 node register、lease renew、SUSPECT、UNAVAILABLE、DRAINING、INACTIVE 状态机。fake clock 下验证每个合法转换；lease 到期在规定窗口内标记 UNAVAILABLE；旧 node_incarnation_id 无法续租或覆盖重启后的新实例；非法跳转被拒绝并记录原因。
F07
MasterGroup 单副本运行时		一个 MasterNode 承载多个逻辑 group；每组隔离元数据、OpLog、snapshot、指标和 RPC queue。单进程启动至少 32 个 group 并写入相同 key，各组数据互不串扰；单组 snapshot/restart 恢复不影响其他组；可按 group 查询 CPU、队列和 metadata bytes。
F08
Group Term 与写 Fencing		所有写请求携带 master_group_id + group_term；旧 primary 无法提交写。将 term 从 N 提升到 N+1 后，term=N 的 Put/Remove/任务完成通知全部返回 STALE_TERM；并发压力下旧 term 成功提交数为 0；读写错误包含 current term。
F09
QUORUM Group 复制与选主		实现 3+ voter 的日志复制、commit index、leader election 和 learner catch-up。3 节点组在任意 1 节点故障后已确认写不丢失并恢复服务；隔离旧 primary 后不能形成双写；失去多数派时拒绝写；learner 追平后状态 hash 与 leader 一致。
F10
ASYNC_STANDBY 模式		实现异步 OpLog replay、replay position、显式提升和 RPO 暴露；不宣称 quorum 语义。注入 replay lag 后指标准确反映差值；提升时返回可能丢失的 position/bytes；未取得 fencing token 的 follower 不可提升；文档/API 明确返回当前 ReplicationMode。
F11
Group Placement 与成员变更		Coordinator 依据故障域和容量放置 replicas，采用 learner-add/catch-up/promote/remove 流程。输入多机架拓扑时同组 replicas 不共故障域；目标不满足约束时计划被拒绝；成员变更中断后可恢复或回滚；任一时刻不产生两个有效 primary。
F12
SlotGroup 静态分配		把 16384 slots 完整且无重叠地分配给多个 MasterGroup，并在服务端强制校验归属。覆盖检查证明每个 slot 恰好一个 owner；非 owner 请求返回包含目标 group 的 MOVED；旧 assignment_generation 返回 STALE_ASSIGNMENT；组内切主不改变 assignment_generation。
F13
SlotGroup 在线迁移		实现 IMPORTING、snapshot copy、committed replay、cutover fencing、MOVED 和 source cleanup。持续并发 Put/Get 时迁移一个 SlotGroup，cutover 后 source/target 对象状态 hash 一致、已确认写零丢失、同一 key 无双 owner；任一阶段 kill/restart 均能恢复或安全回滚。
F14
Segment Control-Owner 路由		按 client_id 将同一 Storage Client 的全部 segments 绑定到一个 MasterGroup，支持 control_generation 和 heartbeat redirect。同一 client 的不同介质 segment 始终落到同组；组内切主只改变 endpoint/term；跨组迁移只提升 control_generation；旧 control owner 无法接受新 heartbeat 或控制写。
F15
跨组任务投递		对象 owner 提交 TaskIntent，至少一次投递到 segment control-owner group，并以 task_id 幂等完成。在投递前、投递后、执行后分别注入崩溃，最终任务恰好产生一次对象状态变化；重复消息不重复分配/释放；任一 term/generation 过期时刷新路由而不是执行。
F16
Resource Capability 与 Telemetry		上报容量、读写带宽、IOPS、并发度、延迟桶、实时使用量、reserved、队列及采样时间。fake Storage Client 上报后 ResourceView 在时限内可见；同一 segment_incarnation 下较小 sample_seq 的样本不会覆盖新样本；超过 freshness 阈值的 segment 被标为 stale；读/写及不同对象大小桶不被合并。
F17
多维 Reservation		以 lease/CAS 原子预留 bytes、bandwidth、IOPS，支持 TTL、幂等键、commit 和 revoke。100 个并发请求不会使任一资源维度超卖；相同幂等键只产生一份 reservation；TTL 后资源可回收；commit/revoke 重复调用结果稳定。
F18
版本化 PlacementPolicy		实现硬约束过滤、可插拔评分、Top-K 有界 reserve 和 ScoreBreakdown；首版使用确定性加权评分。容量不足、故障域冲突和能力不匹配的候选永不入选；固定快照与 policy version 输出完全可重放；每次决策可解释各分项；reserve 尝试不超过配置 K。
F24
Delegated Extent Lease		Storage Client allocator 批量租出互不重叠的 extent range 和多维预算；MasterGroup 在租约内本地分配、后台续租和归还。并发向两个 group 发放租约时 extent 零重叠；旧 segment_incarnation/control_generation 或过期 lease 无法 commit；正常 PutStart 不产生 allocator RPC；耗尽时有界触发后台批量 refill，当前请求快速失败而不无限等待。
F19
Replica Read Selection		在已有 replicas 中根据健康、实时队列、带宽、时延和 locality 排序，不改变持久 placement。注入慢副本后新读流量在观测窗口内转移，恢复后按 hysteresis 回切；无健康副本时返回明确错误；选择变化不产生数据迁移或 metadata ownership 变化。
F20
BackgroundBudget 与 LatencyGuard		分别限制迁移、snapshot、offload、promotion、eviction；根据前台 P99.9 和队列闭环降速/恢复。压测使 P99.9 超阈值后一个控制窗口内降低预算，连续健康窗口后渐进恢复；前台流量不经过 Coordinator；预算过期时采用保守默认值。
F21
Coordinator HA		active/standby lease、fencing token、持久计划恢复；不承担 MasterGroup 日志提交。双实例竞争时最多一个可提交 view；kill active 后 standby 恢复未完成迁移状态；切换期间稳定 group 的 Get/Put 持续成功；旧 Coordinator CAS 全部失败。
F22
可观测性与一致性审计		提供 per-node/group/slot/client/segment 指标、结构化事件和只读审计 API。自动审计能检测 slot 重叠/缺口、同 group 双 primary、replica 跨域违规、stale fencing token 和 reservation 泄漏；健康集群误报为 0；每个异常可定位到实体 ID 和 view revision。
F23
故障注入与兼容性测试框架		可注入进程退出、网络分区、延迟、丢包、磁盘错误、时钟推进和旧版本客户端；输出确定性报告。CI 可独立复现指定 seed；至少覆盖旧 primary 隔离、迁移中断、watch 断线、重复任务、过期 ResourceView；失败报告包含 seed、时间线和最终不变量检查。
+ +

11.1 通用 Definition of Done

+
    +
  • 每项特性有独立 feature flag 或明确的启用条件，关闭时不改变现有单 Master 行为。
    • +
  • 新增持久化结构必须包含 schema/version，并至少验证一次旧版本读取新版本中已知字段的兼容路径。
    • +
  • 所有重试均有 deadline、最大次数和幂等键；验收不得依赖无限等待或人工查看日志。
    • +
  • 性能相关特性必须同时报告吞吐、P50、P99、P99.9 和资源占用，并保存可比较的基线。
    • +
  • 验收报告必须记录代码版本、配置、拓扑、随机 seed、开始/结束时间和不变量检查结果。
    • +
+ +

11.2 依赖关系与并行开发边界

+ 
+基础契约： F01 -> F02 -> F03
+客户端：   F01 + F02 -> F04 -> F05
+Group：    F02 -> F07 -> F08 -> {F09 | F10} -> F11
+Slot：     F04 + F07 -> F12 -> F13
+Segment：  F02 + F07 -> F14 -> F15
+资源调度： F16 -> F17 -> {F18, F24}; F18 + F24 -> F19
+保护闭环： F16 -> F20
+系统 HA：  F03 + F11 + F13 -> F21
+质量体系： F22、F23 从第一阶段开始，并为其他特性提供验收 harness
+
+

+ 箭头表示生产集成依赖，不表示验收必须串行。例如 F04 可用 fake ClusterView 验收，F15 可用两个内存 MasterGroup + 和 fake heartbeat 验收，F18 可使用固定 ResourceView 快照验收。这样各团队可以并行开发，同时保持每项交付可独立判定成功或失败。 +

+ +

12. 演进计划

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
阶段内容收益
阶段一单 Master 暴露 16384 slot 的 ClusterView；客户端实现 slot 计算和路由缓存。不改变部署即可验证客户端路由逻辑。
阶段二多个单副本 MasterGroup 静态分配 SlotGroup；Batch regroup；MOVED/STALE_ASSIGNMENT。核心元数据请求横向扩展。
阶段三引入轻量 Coordinator，管理 view、resource summary 和后台预算。为扩缩容、P99.9 保护和资源协同打基础。
阶段四实现 slot group 在线迁移、snapshot copy、incremental replay、ASK/MOVED cutover。支持在线扩缩容和 rebalance。
阶段五为 MasterGroup 增加 replica、term、组内选主与 fencing；实现 Coordinator active/standby。降低故障影响范围，提高可用性。
+ +

13. 风险与约束

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
风险影响缓解措施
Coordinator 被误用到热路径成为新的 P99.9 瓶颈接口约束：Get/Put 不调用 Coordinator；客户端只周期性或按错误刷新 view。
ResourceView 过期PutStart 选择到高水位或不可用 segmentallocator lease/CAS 二次确认；失败快速换候选或返回错误。
迁移 replay lag 过大cutover 窗口变长lag 超阈值时暂停新迁移，降低前台写入冻结时间。
跨 slot Batch 尾延迟最慢 shard 拉高整批响应per-shard deadline、partial result、bounded retry。
热点 slot group单 shard 局部热点rebalance 避免迁移最热 group；必要时支持 hash tag 约束和 key-level split。
Coordinator split-brain生成冲突 view 或迁移计划Coordinator lease + fencing token；所有 view 更新通过 HA Backend CAS。
term、assignment_generation、control_generation 混用普通切主触发无谓 slot 迁移，或旧 primary/旧 control owner 未被正确隔离分别校验组内领导权、SlotGroup 归属和 client 控制归属；协议字段与错误码独立。
多个 group replicas 共置于同一故障域单节点或单机架故障同时失去 quorumgroup placement 使用反亲和约束，并在部署前做 N-1 failover capacity 校验。
异步主备被当作强一致复制故障提升后丢失已确认写或产生分叉ClusterView 明确暴露 ReplicationMode、commit/replay position 和可承诺的 RPO；需要 RPO=0 时使用 quorum 提交。
+ +

14. 最终建议

+
+

+ 轻量 Coordinator 路线是 Mooncake 分布式元数据面的推荐落地方案：它保留 Redis Cluster 风格的客户端直连和 slot redirect，避免中心化热路径；同时补足 Mooncake 相比 Redis 多出来的物理资源管理、冷热分级、slot 迁移限速和 P99.9 自动保护能力。 +

+
+ +

+ 实施时应坚持四条红线：Coordinator 不代理前台请求；slot owner 是 MasterGroup 而不是裸 MasterNode； + term、assignment_generation、control_generation 分别保护组内领导权、slot 归属和 segment 控制归属；segment_incarnation 隔离重建前后的物理空间；所有迁移动作都必须带 fencing 和可观测的 P99.9 保护阈值。 + 只要这些边界成立，该设计既能横向扩展元数据吞吐，也能在扩缩容和故障场景下保持尾延迟可控。 +

The original supercache branch was 202 commits ahead of and 340 commits behind kvcache-ai/Mooncake:main, so the patch could not be applied via plain 3-way merge (the source commit was not in our local object db). Applied via: git apply --reject 0001-Squashed-commit-of-the-following.patch 76 of 79 files applied cleanly. 3 files required manual conflict resolution due to 340-commit divergence from upstream main:

+配置文件：`mooncake-store/include/master_config.h`，可通过 `master.yaml` 或命令行参数设置。 + +#### `enable_offload`（默认 false） + +- **false**：SSD offload 完全禁用。客户端调用 `OffloadObjectHeartbeat(enable_offloading=false)` 时，Master 清空该客户端的 offload 队列并释放所有 refcnt。对象只有 MEMORY 副本，内存不足时直接 eviction 丢弃。 +- **true**：启用 offload。客户端 `FileStorage` 初始化时注册 LOCAL_DISK segment（`MountLocalDiskSegment`），心跳线程开始工作。PutEnd 或 eviction 时对象可被加入 offload 队列。 + +#### `offload_on_evict`（默认 false） + +- **false（模式 A）**：PutEnd 完成后**立即**将该对象的所有 MEMORY 副本加入 offload 队列。意味着所有写入的数据都会尽快下沉到 SSD，内存中的副本仅作为 RDMA 访问源存在，直到 offload 完成后由 Master 释放。 +- **true（模式 B/C）**：PutEnd 时不做任何 offload 操作。只有当内存使用率超过 `eviction_high_watermark_ratio` 触发 `BatchEvict` 时，才将候选淘汰对象入 offload 队列。**区别**：模式下 B 对象在内存充裕时不会被 offload，仅在被选中淘汰时才持久化到 SSD。 + +#### `offload_force_evict`（默认 false） + +- **false**：在 `offload_on_evict=true` 模式下，如果 offload 队列已满（达到 `offloading_queue_limit_ * kOffloadCapRatio` = 25000），超出上限的候选对象**跳过淘汰**，数据保留在内存中。这会导致本轮 eviction 无法释放足够内存，Master 会打印 WARNING。 +- **true**：在 `offload_on_evict=true` 模式下，offload 队列满时不再跳过，而是**强制 eviction 丢弃数据**。适用于宁可丢失数据也要保证内存可用的场景。 +- **注意**：此开关仅在 `offload_on_evict=true` 时生效。单独设置（模式 D）无任何效果。 + +#### `promotion_on_hit`（默认 false） + +- **false**：LOCAL_DISK 副本被 Get 命中后，后续访问始终走 SSD Load 路径（读磁盘 → staging buffer → RDMA 传输）。 +- **true**：Get 命中 LOCAL_DISK 副本时，`TryPushPromotionQueue()` 被调用，通过 Count-Min Sketch 统计访问频率。频率达到 `promotion_admission_threshold` 的 key 被加入 promotion 队列，心跳线程将其从 SSD 提升回 MEMORY 副本。**效果**：热点数据自动回到内存，后续访问走 RDMA 零拷贝路径，避免 SSD I/O 延迟。 + +#### `promotion_admission_threshold`（默认 2） + +- Count-Min Sketch 的频率阈值。key 被访问的次数（近似）达到此值才有资格 promotion。 +- **设为 1**：任何被访问一次的 LOCAL_DISK key 立即被加入 promotion 队列。适合缓存空间充裕的场景。 +- **设为更大值（如 5）**：需要多次访问才 promotion。避免一次性访问冷数据占用 promotion 资源。 + +#### `promotion_queue_limit`（默认 50000） + +- 全局（所有 shard 共享）的待 promotion 任务上限。 +- **达到上限**：`TryPushPromotionQueue` 中的容量门控拒绝新任务，热 key 暂时留在 SSD。 +- 此上限同时控制 `promotion_in_flight_` 计数器，防止 promotion 占用过多内存。 + +#### `eviction_high_watermark_ratio`（默认 0.85） + +- 内存使用率触发 eviction 的阈值。 +- **设高（如 0.95）**：容忍更高的内存使用率，eviction 触发更晚，留给 offload 的时间窗口更短。 +- **设低（如 0.70）**：更早触发 eviction，内存更充裕，但在 `offload_on_evict=true` 模式下会提前开始 offload。 + +#### `eviction_ratio`（默认 0.05） + +- 每轮 `BatchEvict` 的目标回收比例（相对于总内存）。 +- **设大（如 0.10）**：每轮淘汰更多对象，eviction 频率更低但每轮耗时更长。 +- **设小（如 0.02）**：每轮淘汰少量对象，更平滑但 eviction 线程更频繁工作。 + +### 8.2 Client 端环境变量 + +#### `MOONCAKE_OFFLOAD_FILE_STORAGE_PATH`（默认 `/data/file_storage`） + +- SSD 上的存储目录路径。BucketStorageBackend 在此目录下创建 `.bucket` 和 `.meta` 文件。 +- **不设置**：使用默认路径，需确保该目录存在且有写入权限。 +- **建议**：设置为 NVMe SSD 挂载点，如 `/nvme/mooncake_offload`。 + +#### `MOONCAKE_OFFLOAD_STORAGE_BACKEND_DESCRIPTOR`（默认 `bucket_storage_backend`） + +- `bucket_storage_backend`：默认推荐。多对象合入桶文件（256MB/桶，500 key/桶），支持 FIFO/LRU 淘汰，支持重启恢复。 +- `file_per_key_storage_backend`：每个对象一个文件。适合调试，大规模场景下文件数爆炸。 +- `offset_allocator_storage_backend`：单文件 + 偏移分配器，1024 分片元数据。高并发性能好，但**不支持重启恢复**（启动时 truncates）。 + +#### `MOONCAKE_OFFLOAD_BUCKET_SIZE_LIMIT_BYTES`（默认 256MB） + +- BucketStorageBackend 单个桶文件的大小上限。配置定义在 `mooncake-store/include/storage_backend.h` 的 `BucketBackendConfig::bucket_size_limit`（:181-182）。 +- **分组逻辑**（`GroupOffloadingKeysByBucket()`，`storage_backend.cpp:1880`）：心跳返回的 offload 对象按此大小打包分组。对象被依次加入当前桶，直到桶数据量达到 256MB 或 500 个 key 为止。凑不满一桶的剩余对象暂存在 `ungrouped_offloading_objects_` 中，等下次心跳凑满再写入。 +- **设小（如 64MB）**：桶更小更密集，淘汰粒度更细（LRU/FIFO 淘汰时整桶删除，浪费空间更少），但文件数量增多。 +- **设大（如 512MB）**：减少文件数，但淘汰时整桶删除可能浪费更多有效数据。 +- **注意**：单个对象大小超过此限制时会被跳过（:1911 打印 ERROR 日志）。 + +#### `MOONCAKE_OFFLOAD_BUCKET_KEYS_LIMIT`（默认 500） + +- BucketStorageBackend 单个桶文件的 key 数量上限。配置定义在 `BucketBackendConfig::bucket_keys_limit`（:184）。 +- 与 `bucket_size_limit` 共同控制分组，任一条件先达到即封桶。 + +#### `MOONCAKE_OFFLOAD_BUCKET_EVICTION_POLICY`（默认 `none`） + +- BucketStorageBackend 的 SSD 空间淘汰策略。配置定义在 `BucketBackendConfig::eviction_policy`。 +- `none`：不淘汰。SSD 写满后 offload 失败。 +- `fifo`：淘汰最早创建的桶。 +- `lru`：淘汰最久未被读取的桶（通过 `last_access_ns_` 原子计数器追踪）。 + +#### `MOONCAKE_OFFLOAD_LOCAL_BUFFER_SIZE_BYTES`（默认 1280MB） + +- Load 路径的 staging buffer 大小。从 SSD 读取数据时先写入此 buffer，再通过 RDMA 传输。 +- **设小**：并发 Load 能力受限，大对象可能需要排队等待 buffer 槽位。 +- **设大**：支持更多并发 Load，但占用更多 Host 内存。 +- 此 buffer 会被注册到 Transfer Engine 用于 RDMA 访问。 + +#### `MOONCAKE_OFFLOAD_TOTAL_SIZE_LIMIT_BYTES`（默认 2TB） + +- SSD 磁盘使用上限。达到上限后 BucketStorageBackend 触发淘汰（如有 eviction policy）。 +- **设为 0**：BucketBackend 默认使用磁盘物理容量的 90%。 + +#### `MOONCAKE_OFFLOAD_HEARTBEAT_INTERVAL_SECONDS`（默认 10） + +- 客户端心跳线程的间隔。每次心跳执行：(1) 拉取 offload 任务 (2) 执行 OffloadObjects (3) 执行 ProcessPromotionTasks。 +- **设小（如 3）**：offload/promotion 响应更快，但 Master RPC 压力增大。 +- **设大（如 30）**：减少 RPC 开销，但数据在内存中停留更久，promotion 延迟更高。 + +#### `MOONCAKE_OFFLOAD_USE_URING`（默认 false） + +- **false**：使用标准 POSIX I/O（pread/pwrite）。 +- **true**：使用 Linux io_uring 异步 I/O。每个线程拥有独立的 io_uring ring（无锁），ClientBuffer 注册为 fixed buffer 避免 mmap 开销，配合 O_DIRECT 绕过页缓存。**仅 Linux 可用**。 + +### 8.3 内部硬编码常量 + +| 常量 | 值 | 说明 | +|------|----|------| +| `offloading_queue_limit_` | 50000 | 单客户端

Mooncake 分布式元数据管理面轻量 Coordinator 架构设计

+ +

1. 设计摘要

+
+ 推荐方案： + 采用 Redis Cluster 风格的固定 slot 分片和客户端直连路由，同时引入一个不在前台请求路径上的轻量 Coordinator。 + Coordinator 只负责集群视图、slot 迁移计划、ownership version 与 fencing 发布、资源摘要聚合和后台任务预算调节；GetReplicaList、PutStart、PutEnd 等热路径请求仍由客户端直接访问 slot 所属 MasterGroup 的 current primary。 +
+ +

1.1 术语与层次

+ + + + + + + + + + +
术语本文中的唯一含义
MasterNode一个可寻址的 Master 进程实例；是部署、租约和故障域单位。
MasterGroup一个复制组；是日志提交、主备切换和一致性单位，包含一个 current primary 和若干 replica。
Slot由 key hash 得到的固定路由编号。
SlotGroup一组连续或离散 slot；是负载统计和组间迁移单位。
Slot owner拥有 SlotGroup 的 MasterGroup，而不是某个永久固定的 MasterNode。
Group primaryMasterGroup 当前接收强一致前台请求的 MasterNode，随 term 变化。
+

+ 下文若使用“Master 服务”，仅泛指 MasterNode 上运行的服务。路由、所有权或 failover 描述必须明确使用 + MasterGroup、Group primary 或 MasterNode，避免“Master Shard”同时指进程、复制组和 slot 分片。 +

+ +

1.2 Generation、Term、Revision 与 Fencing

+

+ 本设计不再把所有版本都称为 epoch，而是只区分三种语义：generation/term 是 fencing token， + 用于隔离旧 owner；revision 只用于快照发布、CAS 和增量 watch；sequence 只用于同一数据流内的样本排序。 + 只有 generation/term 会决定请求是否有权改变状态，revision 和 sequence 都不能授予写权限。 +

+ + 
+初始状态：SlotGroup S belongs to MasterGroup G1, assignment_generation = 7
+
+Client C1 cached: S -> G1, generation 7
+Coordinator migrates S: G1 -> G2, generation becomes 8
+
+C1 sends Put(key, owner=G1, assignment_generation=7)
+G1/G2 compares request generation with durable assignment:
+  7 < 8  -> reject STALE_ASSIGNMENT or MOVED(S, G2, 8)
+
+Without assignment_generation:
+  delayed C1 or old G1 might continue modifying S after cutover,
+  creating two owners and divergent object metadata.
+
+ +
+ Generation/term 的作用不是发现故障，而是隔离旧状态。 + lease/heartbeat 用于判断参与者可能失活；generation/term 用于在发生切换后证明请求仍属于当前一代。 + 仅检测到旧 primary 断连是不够的，因为它可能仍在运行，只是发生了网络分区。 +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
字段类别作用域何时递增防止的问题旧值处理
view_revisionRevision整个 ClusterView任意已发布集群视图发生变化增量更新乱序、旧 view 覆盖新 view客户端忽略旧 view；watch 缺口时重新读取全量 view

budget_revisionRevision一版 BackgroundBudgetCoordinator 调整后台任务预算旧预算重新放大迁移或 offload 流量忽略旧预算；当前预算过期则使用保守默认值
+ +

+ 四个 fencing scope 是 group term、slot assignment generation、client control generation + 和 segment incarnation。前三者可共享 FencingToken{scope_id, generation} 的实现；segment 使用 UUID incarnation token。 + 它们属于不同状态机，不能跨 scope 比较。 + revision/sequence 使用无符号 64 位单调计数器；incarnation 使用启动或重建时生成的 UUID，避免依赖旧进程持久化计数器。 +

+ 
+// 通用比较规则，不表示存在一个全局 generation。
+struct FencingToken {
+  string scope_id;
+  uint64_t generation;
+}
+
+SnapshotRevision = uint64_t;   // view/resource/budget，只用于排序、watch 和 CAS
+IncarnationId = UUID;          // node/segment，每次重启或重建生成新值
+StreamSequence = uint64_t;     // telemetry，在同一 incarnation 内单调递增
+
+ +

1.2.1 Term 为什么单独命名

+

+ term 本质上是 MasterGroup 的领导权 generation，但保留 term 这个名称是为了和 Raft 等复制协议一致。 + QUORUM 模式由组选举产生更高 term；ASYNC_STANDBY 模式由 Coordinator 在取得独占 fencing token 后授权更高 term。 + 无论采用哪种模式，数据写入权威方都必须检查 term。只把新 primary 地址写入服务发现，而不在提交点检查 term，不能防止双主。 +

+ +

1.2.2 Fencing 是什么

+

+ Fencing（隔离旧持有者）是“在最终写入点拒绝旧 token”的机制，generation/term/incarnation 是本文的 fencing token。 + 检查必须发生在真正改变状态的地方，例如 MasterGroup 日志提交、segment allocator reserve/free、HA Backend CAS， + 而不能只在客户端或入口 RPC 检查一次。否则请求通过检查后发生切主，延迟请求仍可能写入。 +

+ +

1.3 一致性与故障恢复基础概念

+ + + + + + + + + + + + + + + + + + + + + + + + + +
概念解释及本文中的用途
Lease有到期时间的临时所有权/存活声明，持有者必须续租。用于故障检测和资源自动回收，但不能代替 fencing。
CASCompare-And-Swap：仅当持久化值仍等于预期版本时才更新。用于保证两个 Coordinator 或迁移流程不能同时提交冲突 owner。
Quorum复制组的多数派。3 voter 中至少 2 个确认后提交，可容忍 1 个故障；失去多数派时宁可拒绝写，也不能产生两个合法 primary。
OpLog按顺序记录元数据状态变化的操作日志。replica 和迁移 target 先加载 snapshot，再 replay 后续 OpLog。
Snapshot某个一致性位置上的完整状态快照，用于避免从第一条 OpLog 开始恢复。snapshot 必须携带其对应的 log/commit position。
Replay lagtarget/replica 已应用位置与 source committed position 的差距。只有追到 cutover position 才能安全接管。
RPORecovery Point Objective，可接受的数据丢失范围。QUORUM 已提交写目标是 RPO=0；异步主备的 RPO 由尚未 replay 的日志决定。
RTORecovery Time Objective，从故障发生到恢复服务允许的时间；受故障检测、选主和 replay lag 影响。
Idempotency key同一逻辑操作重试时保持不变的 ID，使重复请求只产生一次状态变化，用于 reservation 和后台 Task。
ResourceView容量、带宽、IOPS 和健康状态的近实时只读快照，用于选候选；它可能过期，因此最终 reserve 仍需 allocator 原子确认。
Reservation带 TTL 的临时资源承诺。PutStart 预留、PutEnd 提交、PutRevoke/超时释放，以避免并发请求超卖。
Replica descriptor描述一个对象副本所在 segment、offset/length、介质类型和访问参数的元数据；它不是对象数据本身。
Failure domain共享故障风险的边界，例如进程、机器、机架或 AZ。副本跨域放置是为了避免一次故障同时损坏全部副本。
Locality调用方与 segment 之间的 NUMA、主机、机架、AZ 或网络 fabric 距离，用于估算访问时延和网络成本。
Rendezvous hash对“实体、候选节点”组合计算稳定分数并选最高者；候选集合变化时只移动较少实体。本文用于生成初始 control-owner 建议，最终映射仍由 Coordinator 显式提交。
Hard constraint不满足就绝不能选择的条件，例如容量不足、介质能力不符或副本处于同一故障域；与可权衡的软评分分开处理。
Dominant resource某候选节点上占用比例最高的资源维度。例如容量只占 20% 但带宽占 90%，其主导资源是带宽，不能因容量充足继续放置。
Hysteresis进入和退出某状态使用不同阈值或连续观测窗口，避免热点副本、预算和读路由在临界值附近频繁来回切换。
P99.999.9% 请求时延不超过的值，即每 1,000 个请求约有 1 个更慢；用于约束极端尾延迟，而不仅是平均性能。
MOVEDSlotGroup 已稳定归属于另一个 MasterGroup；客户端应更新本地长期路由并重试。
ASKSlotGroup 正在迁移，客户端仅对本次请求访问 importing group，不永久覆盖本地 owner。

1.4 一次 Put 请求如何使用这些版本号

+ 
+1. Client 从 ClusterView(view_revision=100) 得到：
+     slot 42 -> SlotGroup S7(assignment_generation=8)
+             -> MasterGroup G2(term=12)
+             -> primary endpoint B
+
+2. Client 向 B 发送 PutStart：
+     {group=G2, term=12, slot=42, assignment_generation=8, request_id=R}
+
+3. B 在写入 PROCESSING 元数据前检查：
+     a. 自己仍是 G2 term 12 的 primary；否则 NOT_PRIMARY/STALE_TERM
+     b. slot 42 仍属于 G2 且 generation=8；否则 MOVED/STALE_ASSIGNMENT
+     c. request_id R 是否已处理；若是则返回相同结果
+
+4. B 使用本地 ResourceView 选择目标存储节点，并从本组的 DelegatedExtentPool
+   分配已由后台租入的空间和资源预算。常态 Put 不同步访问 Coordinator 或远端 allocator。
+
+5. B 写入 PROCESSING 元数据，将变更异步复制给 standby，然后返回 replica descriptors。
+
+6. Client 写数据并发送 PutEnd(R)。B 再次检查 term、assignment_generation 和 request_id，
+   然后把对象从 PROCESSING 转为 COMPLETE，并异步复制该变更。
+
+

+ view_revision 只说明客户端使用哪一版路由快照，不授予写权限；真正保护写正确性的是对应作用域的 + term、assignment_generation、segment_incarnation 以及幂等 request_id。即使客户端 view 不是最新， + 服务端也能拒绝危险写，并通过错误码引导客户端刷新。 +

+ +
+ 和 Redis 的关系： + Redis Cluster 没有独立 Coordinator，slot ownership 和 failover 信息由节点 gossip 传播，reshard 通常由外部工具驱动。 + Mooncake 的不同点在于 Master 还承担物理空间管理、冷热分级、租约、client liveness 和后台迁移任务。 + 因此引入轻量 Coordinator 是为了管理 Mooncake 特有的全局控制问题，而不是替代 Redis Cluster 的去中心化热路径。 +
+ +
+ P99.9 原则： + Coordinator 不能成为 P99.9 热路径依赖。客户端在正常读写时不访问 Coordinator；Coordinator 故障只影响扩缩容、rebalance、跨组迁移、视图发布和预算调节，不影响已有稳定 group 的前台读写或 quorum 组内选主。 +
+ +

2. 设计目标与非目标

+

2.1 设计目标

+
    +
  • 将对象元数据按固定 slot 拆分到多个 MasterGroup，解除单 MasterNode 的 CPU、锁和 RPC 瓶颈。
    • +
  • 保持前台请求路径短：客户端计算 slot，直接访问对应 MasterGroup 的 current primary。
    • +
  • 在扩缩容、slot 迁移、failover、冷热分级、资源压力下保持 P99.9 时延稳定。
    • +
  • 用轻量 Coordinator 管理 slot view、资源摘要和后台预算，但不代理元数据请求。
    • +
  • 支持兼容式演进：单 Master 先暴露全量 slot view，再逐步引入多 Master 和迁移能力。
    • +
+ +

2.2 非目标

+
    +
  • 不把 Coordinator 做成所有元数据 RPC 的代理。
    • +
  • 不要求跨 slot Batch 操作具备全局原子性；默认提供逐 key 成功/失败结果。
    • +
  • 不要求第一阶段实现完整自动 rebalance；可以先由管理命令触发迁移计划。
    • +
  • 不把物理数据迁移放入 Master 进程内同步执行；Master 只负责元数据状态机和任务编排。
    • +
+ +

3.1 核心原则

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
原则含义
热路径去中心化客户端通过本地 slot map 直连 owner MasterGroup 的 current primary，不经过 Coordinator。
控制路径集中但轻量Coordinator 管理 view、跨组迁移、group placement、fencing 发布和预算，不保存每个对象的热路径状态。
对象状态单 owner同一个 key 的 Put/Get/Evict/Offload/Promotion 只由当前 slot owner MasterGroup 提交。
所有权带 fencing token组内 primary 用 term，slot 改属用 assignment_generation，segment 控制权改属用 control_generation；三者不能混用。
后台任务可退让迁移、snapshot、eviction、offload、promotion 必须受预算控制，P99.9 超阈值时自动降速。
+ +

4. 组件职责

+

4.1 Mooncake Client / SDK

+
    +
  • 维护本地 ClusterView 和 slot map 缓存。
    • +
  • 计算 slot = hash(tenant_id, key) % 16384。
    • +
  • 按 slot owner MasterGroup 解析 current primary endpoint 并直连。
    • +
  • 处理 MOVED、ASK、NOT_PRIMARY、STALE_TERM、TRYAGAIN、STALE_ASSIGNMENT。
    • +
  • 对 Batch 请求按 owner regroup，并按原始 key 顺序合并响应。
    • +
  • 设置 per-RPC deadline，避免单个 Master 慢请求拖垮 P99.9。
    • +
+ +

4.2 MasterGroup 与其 current primary

+
    +
  • MasterGroup 负责一组 SlotGroup 的对象元数据；current primary 对外服务，replica 按复制模式同步状态。
    • +
  • 执行对象生命周期状态机：PutStart、PutEnd、PutRevoke、Remove、Evict。
    • +
  • 维护对象租约、hard pin、soft pin 和访问热度统计。
    • +
  • 生成和消费对象级后台任务，例如 copy、move、offload、promotion。
    • +
  • 由 current primary 向 Coordinator 上报前台时延、队列深度、slot 负载、资源使用摘要和迁移状态。
    • +
  • 订阅 Coordinator 发布的 cluster view、resource view 和 background budget。
    • +
+ +

4.3 Lightweight Coordinator

+
    +
  • 维护 MasterNode incarnation、MasterGroup membership、slot ownership、assignment generation 和 view revision。
    • +
  • 生成扩缩容和 rebalance 计划。
    • +
  • 协调 slot group 迁移状态机，但不搬运前台请求。
    • +
  • 汇总 segment resource summary，发布近实时 ResourceView。
    • +
  • 根据 P99.9、队列深度、CPU、网络、replay lag 动态调节后台任务预算。
    • +
  • 观察组内选主结果并发布带 term 的新 primary endpoint；通过 HA Backend fencing 防止旧 primary 继续写。
    • +
+ +

4.4 HA Backend

+
    +
  • 持久化 cluster view、slot ownership、membership lease 和 coordinator lease。
    • +
  • 保存 MasterGroup 的 OpLog、snapshot catalog、commit position 或恢复指针。
    • +
  • 在 Coordinator 故障时支持新 Coordinator 接管。
    • +
+ +

4.5 Storage Client / Segment

+
    +
  • 向 Master 或 Resource Registry 上报 segment 容量、水位、健康状态。
    • +
  • 执行数据路径操作，例如 RDMA 写、SSD offload、本地 promotion、replica clear。
    • +
  • 通过 task heartbeat 获取 offload/promotion/copy/move 任务。
    • +
+ +

4.6 Segment 与 MasterGroup 的归属关系

+
+ 结论： + key 的 slot owner 和 segment 的 control owner 是两套独立映射。 + slot owner 管对象及其 replica 状态；segment control owner 管 segment 注册、心跳、健康状态和客户端级任务通道。 + 一个对象可以被放到任意健康 segment 上，因此对象的 slot owner 不要求等于该 segment 的 control owner。 +
+ +

+ 推荐按 client_id 而不是按 segment_id 分配 segment control owner：同一个 Storage Client + 注册的 MEMORY、LOCAL_DISK、NOF_SSD 等全部 segment 由同一个 control-owner MasterGroup 管理，heartbeat 发往该组 current primary。 + 这样 client liveness、一次 heartbeat 中携带的多个 segment 状态以及下发给该 client 的任务队列都落在同一处， + 不需要拆分一次 heartbeat。Coordinator 在 ClusterView 中持久化该映射；初次加入时可用 + rendezvous hash 选择 control-owner MasterGroup，并在负载不均衡时显式迁移，而不能由各 MasterNode 独立计算后直接生效。 +

+ + 
+对象控制面：hash(tenant_id, key) -> slot -> slot owner MasterGroup -> current primary
+Segment 控制面：client_id -> client control-owner MasterGroup -> current primary -> 全部 segments
+
+例：
+  Group G1 owns slots [0, 4095]       and controls Client X -> [Segment X.mem, X.ssd]
+  Group G2 owns slots [4096, 8191]    and controls Client Y -> [Segment Y.mem]
+  Group G3 owns slots [8192, 16383]   and controls Client Z -> [Segment Z.mem, Z.nof]
+
+  key K belongs to a slot owned by G2
+  K replicas may be placed on X.mem and Z.nof
+  G2 owns K metadata and decides create/remove/offload/promotion
+  G1 controls X.mem health; G3 controls Z.nof health
+  Storage Client X/Z remains the authority that atomically reserves/frees physical extents
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
状态或动作唯一写入者/权威方其他 Master 如何使用
key、replica descriptor、对象状态机key 的 slot owner MasterGroup非 owner 返回 MOVED，不得修改
client lease、segment mount/unmount、health、watermarkclient control-owner MasterGroup通过只读 ResourceView 获取摘要
物理 extent 的 reserve/freeStorage Client 的 allocator，使用 lease/CAS 和幂等 request_idslot owner 直接请求 allocator；control owner 不在每次 Put 的同步链路中
offload/promotion/copy/move 的对象决策对象 slot owner MasterGroup任务经 client control owner 的 heartbeat 通道投递，完成后回报 slot owner
segment control owner 映射Coordinator + HA Backend CAS所有 Master 订阅同一版本化映射
+ +

+ 因而“G1 管理 Segment X”只表示 G1 是 X 所属 client 的控制面 owner，并不表示只有 G1 的 slot + 才能在 X 上放 replica。所有 slot-owner group 都可依据 ResourceView 选择 X，但最终空间分配必须由 X 所在 + Storage Client 的 allocator 原子确认，避免多个 Master 根据过期容量摘要重复分配。 +

+ +

4.6.1 Owner 选择、故障与迁移规则

+
    +
  • 初始分配：Coordinator 对 client_id 和 ACTIVE MasterGroup 集合做 rendezvous hash，选择一个 control-owner group；组内 primary/replica 由该组成员关系决定。hash 可叠加连接数、segment 数和 heartbeat QPS 权重。
    • +
  • 稳定性：MasterNode 加入或退出时不自动重算全部 client；只有 Coordinator 生成并提交的新 group 映射才改变 owner，避免大规模心跳抖动。
    • +
  • 故障切换：current primary 失效后由组内复制协议选出新 primary 并递增 term；Coordinator 发布 endpoint。只有 client 从一个 control-owner group 迁到另一个 group 时才递增 control_generation。Storage Client 同时校验 term 和 control_generation，旧 primary 必须被 fencing。
    • +
  • 主动迁移：先让 target group 导入 client/segment 快照并接收增量状态，再递增 control_generation 切换 heartbeat，最后清理 source group；迁移期间对象 slot ownership 不变。
    • +
  • 故障域：同一 MasterGroup 的 replicas 尽量跨节点、机架或 AZ；同一 client 的 segment 不拆给多个 control-owner group，除非未来 heartbeat 协议支持按 segment 独立分流。
    • +
+ +
+ 不要混淆三种变化： + MasterGroup 组内切主只提升 term；SlotGroup 跨组迁移改变对象元数据归属并提升 assignment_generation； + client control owner 跨组迁移改变 segment 控制归属并提升 control_generation。任何一种变化都不应隐式触发另外两种。 +
+ +

4.6.2 跨组任务投递

+

+ 当对象 slot owner 与目标 segment control owner 不同，不能依赖两个 group 的内存队列或分布式事务。 + 对象 owner 先在本组 OpLog 中提交 TaskIntent，再以至少一次语义投递到 control-owner group；后者通过 + Storage Client heartbeat 下发。完成通知可重复发送，由对象 owner 根据 task_id 幂等提交最终 replica 状态。 +

+ 
+TaskEnvelope {
+  UUID task_id;
+  string object_owner_group_id;
+  uint64_t object_group_term;
+  uint32_t slot_id;
+  uint64_t assignment_generation;
+  string client_control_group_id;
+  uint64_t control_generation;
+  UUID target_segment_id;
+  TaskType type;
+}
+
+

+ 任一 fencing generation/term 不匹配时不得盲目执行：投递方刷新 ClusterView 后重新路由，执行方使用 + task_id 去重。这样组内切主、SlotGroup 迁移或 client control owner 迁移都不会造成任务丢失或重复修改对象状态。 +

+ +

4.7 多 Master 的分组：MasterGroup 与 MasterNode

+
+ 推荐模型： + 用 MasterGroup（也可称 ReplicaSet）表达主备复制关系，用不同 MasterGroup 之间的 slot + 分配表达 shard 分担关系。MasterNode 只是进程/机器实例，不应被永久标记成全局 primary、standby 或 shard。 +
+ + 
+                         Cluster
+                            |
+          +-----------------+-----------------+
+          |                                   |
+    MasterGroup G1                       MasterGroup G2
+    owns slot groups 0..3                owns slot groups 4..7
+    (shard relation with G2)             (shard relation with G1)
+          |                                   |
+    primary: Master A                    primary: Master C
+    standby: Master B                    standby: Master D
+    (A/B are replication peers)          (C/D are replication peers)
+
+Client route:
+  key -> slot -> slot_group -> master_group -> current primary endpoint
+
+ +

+ 因此，“A 和 B 是主备”表示它们是同一个 MasterGroup 的复制成员；“A 和 C 分担 shard”更准确地说是 + A 所在的 G1 与 C 所在的 G2 分别拥有不同 slot group。主备关系发生在组内，分片关系发生在组间， + 两者不应使用同一个 role 字段表达。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
抽象职责所有权/版本
MasterNode描述进程地址、故障域、容量、存活租约；可承载一个或多个 group replicanode_id + node_incarnation_id
MasterGroup对象元数据的一致性与故障切换单元，包含一个 primary 和若干 standbygroup_id + term
GroupMember描述某个 node 在某个 group 内的 PRIMARY、VOTER、LEARNER 等角色角色只在 group 内有效
SlotGroupAssignment把一段 slot 映射到一个 MasterGroup；扩缩容时迁移该映射及其状态assignment_generation
+ +

4.7.1 两种部署方式

+

方式一：节点独占 group，建议作为第一阶段。

+ 
+G1 = {A primary, B standby}
+G2 = {C primary, D standby}
+
+
    +
  • 关系直观，故障和容量边界容易分析，运维简单。
    • +
  • standby 正常情况下资源利用率较低，可提供只读诊断，但不应承接强一致前台写。
    • +
  • 两副本只能实现异步或同步主备，无法在网络分区下形成安全多数派；需要 quorum 强一致时，每组至少放置 3 个跨故障域 voter。
    • +
+ +

方式二：一个节点承载多个 group replica，用于提高利用率。

+ 
+G1 = {A primary, B standby, C standby}
+G2 = {B primary, C standby, A standby}
+G3 = {C primary, A standby, B standby}
+
+
    +
  • A、B、C 都承担一部分 primary shard，同时又互为其他 group 的 replica；“standby”是非 primary replica 的统称，QUORUM 模式对应 VOTER，ASYNC_STANDBY 模式对应 FOLLOWER。
    • +
  • 调度必须限制同一 node 的 primary 数、总 QPS、metadata bytes、replay 带宽和故障恢复负载。
    • +
  • 同一 group 的两个 replica 不能落在同一进程或同一故障域；否则节点或机架故障会同时丢失主备。
    • +
  • 一个 node 故障后，不能让其所有 standby 同时提升到同一个剩余 node，需要预先校验 failover capacity。
    • +
+ +

4.7.2 分组与迁移规则

+
    +
  • 组内切主：只改变 MasterGroup.term 和 primary member，不改变该组拥有的 slot；客户端刷新 endpoint 即可。
    • +
  • 组间迁移：把 SlotGroup 从 source MasterGroup 复制到 target MasterGroup，完成 snapshot/replay 后递增 assignment_generation 并切换归属。
    • +
  • 成员变更：采用 learner 加入、追平、转 voter、移除旧 member 的联合配置流程，不能直接覆盖成员列表。
    • +
  • 分组粒度：MasterGroup 数量应多于物理节点数，才能细粒度均衡；但每组都有 OpLog、snapshot 和 heartbeat 成本，应使用固定数量的虚拟 group，而不是每个 slot 一个复制组。
    • +
  • Coordinator 边界：Coordinator 决定 group membership 和 slot-to-group assignment；组内复制协议决定日志提交和 primary，不让 Coordinator 进入每次元数据写的提交路径。
    • +
  • Segment 控制归属：ClientControlOwner 也指向 MasterGroup，而不是裸 node；heartbeat 访问该组当前 primary，组内切主不改变 client 的逻辑归属。
    • +
+ +
+ 关键约束： + 如果没有真正的组内复制协议和提交法定人数，只能称为 primary/standby snapshot failover，不能宣称强一致 HA。 + 此时 primary 故障可能丢失尚未同步的 OpLog，ClusterView 必须暴露相应的 RPO 状态。 +
+ +

5. 数据模型

5.1 ClusterView

+ 
+struct ClusterView {

+  uint32_t slot_count;          // default: 16384

+  string owner_master_group_id;

+}
+
+ +

5.2 ResourceView

+ 
+struct ResourceView {

+  ClusterPressure pressure;
+}
+

+  ResourceCapability capability;
+  ResourceTelemetry telemetry;
+  FailureDomain failure_domain;
+  NetworkLocality locality;
+  SegmentHealth health;
+}
+
+ +

5.3 多维资源、工作负载与放置抽象

+
+ 设计原则： + 不再用单一 used_bytes / capacity_bytes 判断节点优劣，而把“节点能提供什么”、 + “对象需要什么”和“当前还承诺了多少资源”分开建模。容量大但带宽小的 segment 可承载冷数据， + 容量小但带宽大的 segment 可承载热点副本；同一对象的持久放置与实时读流量也可以由不同策略处理。 +
+ +

建议增加以下六类稳定抽象：

5.3.1 放置和读路由必须解耦

+
    +
  • Replica Placement：决定数据存在哪些 segment，主要优化容量、持久性、写入代价和故障域。
    • +
  • Replica Read Selection：在已有 replica 中按实时带宽、队列、时延和调用方 locality 选择读源；不因为一次流量变化立即搬数据。
    • +
  • Tiering / Rebalance：根据较长时间窗口的热度和资源价格决定复制、迁移、offload 或 promotion，带 hysteresis 和冷却时间。
    • +
+

+ 例如，大容量低带宽节点可保存完整冷副本，小容量高带宽节点只保存工作集热点副本；读请求优先访问高带宽副本， + 高带宽层容量不足时淘汰热点副本不会删除低带宽层的持久副本。这样“容量归属”和“流量归属”不再被一个 placement 决策绑死。 +

+ +

5.3.2 可演进的算法接口

+ 
+PlacementResult Place(PlacementContext ctx) {
+  candidates = FilterByHardConstraints(
+      ctx.resource_view, ctx.intent, ctx.excluded_failure_domains);
+
+  candidates = CheckMultiResourceFeasibility(

6. 热路径流程分析

+

6.1 GetReplicaList

+ 
+Client
+  -> calculate slot(key)
+  -> find owner from local ClusterView
+  -> RPC GetReplicaList(key, tenant_id, master_group_id, group_term,
+                        slot_id, assignment_generation)
+
+Owner MasterGroup current primary
+  -> validate master_group_id, term, slot ownership and assignment_generation
+  -> lookup object metadata in local slot group
+  -> refresh lease / hotness counter
+  -> rank readable replicas by current latency / bandwidth / caller locality
+  -> if promotion-on-hit eligible: enqueue promotion task only
+  -> return replica list
+
+Client
+  -> if OK: use replica descriptors for data path
+  -> if MOVED/STALE_ASSIGNMENT: refresh slot map and retry
+  -> if TRYAGAIN: short backoff within request deadline
+
+ +

+ P99.9 控制点：读路径只访问一个 MasterGroup primary；promotion 不在前台执行；slot view 或 group term 过期通过重定向快速修正；RPC 有 deadline。 +

+ +

6.2 PutStart / PutEnd

+ 
+PutStart:
+Client -> owner MasterGroup current primary
+  -> validate group term and assignment generation
+  -> build WorkloadIntent from request policy and observed history
+  -> filter hard constraints and score candidates from local ResourceView
+  -> allocate from the local DelegatedExtentPool
+  -> write object PROCESSING metadata
+  -> enqueue asynchronous standby replication
+  -> return replica descriptors
+
+Data Path:
+Client writes object data to selected replicas
+
+PutEnd:
+Client -> owner MasterGroup current primary
+  -> validate group term and assignment generation
+  -> transition PROCESSING -> COMPLETE
+  -> enqueue asynchronous standby replication
+  -> optionally enqueue offload task
+  -> return OK
+
+ +

+ P99.9 控制点：PutStart 不向 Coordinator 或远端空间分配服务同步请求资源；ResourceView 和 DelegatedExtentPool 都在本地。 + 本地 extent 不足时快速失败并触发后台补充，禁止把远端 refill 或长时间候选扫描退化到当前请求中。 +

+ +

6.3 Batch 请求

+ 
+Client input keys: [k1, k2, k3, k4, k5]
+
+Regroup by owner:
+  Master A: [k1, k4]
+  Master B: [k2, k5]
+  Master C: [k3]
+
+Parallel RPC:
+  send sub-batches concurrently with per-shard deadline
+
+Merge:
+  output results in original key order
+
+ +

+ P99.9 控制点：子批次并行，单个慢 shard 不阻塞其他 shard 的结果；业务可选择 fail-fast、partial success 或 bounded retry。 +

+ +

6.4 时序图与当前 Mooncake 对比

+

+ 本节只统计正常稳定状态，不把首次建连、ClusterView watch、MOVED/STALE_TERM 重试和故障恢复计入常态热路径。 + 当前实现以代码中的单个全局 MasterService 为基线：客户端 Get 调用一次 + GetReplicaList；Put 调用 PutStart、执行数据传输、再调用 PutEnd； + segment allocator 由 Master 进程内的 segment_manager_ 访问。当前 1024 个 metadata shard 是进程内锁分片， + 不是分布式 MasterGroup。对应代码入口为 client_service.cpp::Get/Put、 + master_client.cpp::GetReplicaList/PutStart/PutEnd 和 master_service.cpp::GetReplicaList/PutStart/PutEnd。 + 图中的当前基线是默认非 HA 模式；当前 HA 仍是单个 active Master，客户端 RPC 形状不变，leader watch 在后台执行。 + 若某种 HA 配置把 OpLog 外部持久化同步放入请求路径，应把该耗时作为单独基线实测，不能与默认模式混合比较。 +

+

+ 本节时序图使用 Mermaid 11 sequenceDiagram 绘制；HTML 通过官方推荐的 ESM 方式从 jsDelivr 加载。 + 无网络环境仍会保留 Mermaid 源码，可在文档构建阶段改为 vendored Mermaid 或预渲染 SVG。 +

+ +

+
+ +

+ 正常 Get 的通信次数与当前实现相同，新增 slot hash、view lookup、term/generation 比较均为本地 CPU 操作。 + 但当前 Get 会刷新对象 read lease；如果新设计把每次 lease/hotness 更新同步复制到 quorum，Get 将额外增加一个 group commit RTT， + 形成明显劣化。推荐把访问热度和 lease heartbeat 做本地聚合、异步批量复制，并规定新 primary 在提升后至少一个 + max_read_lease_ttl 窗口内禁止回收旧 replica。这样 failover 期间保守占用空间，但正常 Get 不增加网络轮次。 +

+ +

6.4.5 Put：新设计快路径

+

+ Put 只采用这一条前台路径。为避免每次 PutStart 同步访问空间分配服务，增加 DelegatedExtentLease：Storage Client allocator + 预先把互不重叠的 extent range、bytes/bandwidth/IOPS budget 租给 MasterGroup。Group primary 在租约范围内本地切分， + 后台低水位时批量续租。lease 必须携带 segment_incarnation + control_generation + owner_group_id + group_term + expire_at， + Storage Client 不得把同一 extent 同时租给两个 group。 +

+

+    end
+    Note over Client,Primary: Same synchronous metadata RPC count as current = 2
+    Note over Primary,Allocator: Normal PutStart allocator RPC = 0, synchronous replication RTT = 0
+
+

+ 该快路径在同步通信形状上与当前实现一致：2 次 metadata RPC、按配置副本数执行数据写、0 次逐对象 allocator RPC、0 次同步复制 RTT。 + 代价是 PROCESSING/COMPLETE 在 follower 确认前已经向客户端返回，因此 ASYNC_STANDBY 存在非零 RPO。 + 因而本设计的 Put 语义必须明确公布这一 RPO，不能把异步复制描述为 RPO=0 的强一致提交。 +

+

+ primary 切换后，新 term 不得继续本地切分旧 term 的 delegated range；旧 range 进入 quarantine，等待 lease TTL + 到期或 allocator 明确回收，新 primary 获取新 range。这样即使旧 primary 暂时仍可访问数据网络，也只可能在隔离范围内产生孤儿写， + 不会与新 primary 重复分配同一 extent。该策略用临时容量占用换取正常 PutStart 的零 allocator RTT。 +

+ +

+            G3-->>Client: results 3
+        end
+        Client->>Client: merge in original key order
+    end
+
+

+ 当前跨任意 key 的 Batch 只发 1 个 Master RPC；新设计涉及 G 个 owner 时发送 G 个并行 RPC。 + 消息数从 2 个单向消息增加为 2G，但理想情况下仍是 1 个串行网络轮次。它提高总吞吐和故障隔离， + 但整批完成时延变为所有 sub-batch 的最大值；因此必须支持 per-group deadline、partial result，以及限制最大并发 group 数。 +

+ +

6.4.7 Storage heartbeat 与后台任务

+        Control-)Object: idempotent completion batch
+    end
+    Note over Storage,Control: Per heartbeat RPC count unchanged, cross-group messages are asynchronous
+
+

+ 每类 heartbeat 的前台 RPC 次数不变，Coordinator 不参与。新增的跨组 TaskEnvelope/Completion 是后台批量通信， + 不进入应用 Get/Put 的同步关键路径；如果实现成每对象同步转发，则会放大 RPC，违反本设计。 +

+ +

6.4.8 通信次数与性能结论

Get metadata1 client-Master RPC1 client-group-primary RPC；本地路由；无 Coordinator0基本不劣化；多 group 可降低锁和 CPU 排队。禁止每 Get 同步复制 lease/hotness。
Get data1 replica data read1 replica data read0不劣化；动态 read selection 可能改善 locality 和尾延迟。
Put metadata（新设计快路径）PutStart + PutEnd = 2 RPC2 client RPC；delegated extent 本地分配；replication 异步0通信形状与当前一致，目标为基本不劣化；代价是明确的非零 RPO。

跨组 Batch metadata1 Batch RPC，2 个单向消息G 个并行 sub-RPC，2G 个单向消息理想值 0；仍为 1 round消息数增加；吞吐可扩展，但整批 P99.9 受最慢 group 影响。
Storage heartbeat每类 heartbeat 1 RPC每类 heartbeat 1 RPC 到 control-owner primary0不劣化；跨组任务必须批量异步。
稳定状态 CoordinatorHA client watch backend周期/watch 更新 ClusterView 和 budget0（不在请求路径）不影响单请求时延，但增加低频控制面流量。
+ +
+ 结论： + Put 采用 delegated extent 和 ASYNC replication 的唯一快路径，并配合并行 sub-batch、异步 lease/hotness 和后台任务批量化后， + Get、单 key Put 和 heartbeat 的同步 RPC/网络轮次可以与当前实现保持一致，因此设计目标可以设为“基本不劣化”。 + 该 Put 路径采用 ASYNC_STANDBY，允许非零 RPO；接口、监控和验收结果必须明确披露这一语义。 +
+ +

6.4.9 必须通过的性能验收

+
    +
  • 相同硬件、对象大小、replica 数和并发度下，对比当前单 Master 与采用 ASYNC_STANDBY 的新设计快路径。
    • +
  • 分别测试 4 KiB、64 KiB、1 MiB、16 MiB；报告 metadata-only 与 end-to-end 的吞吐、P50、P99、P99.9。
    • +
  • Get：单副本 MasterGroup 相比当前实现在无 CPU 饱和时 P99.9 增幅目标不超过 5%；超出则必须给出 route/serialization/queue breakdown。
    • +
  • Put：ASYNC + delegated extent 快路径相比当前实现在无 CPU 饱和时 metadata P99.9 增幅目标不超过 5%；分别报告 local allocation、async enqueue 和 data transfer。
    • +
  • Batch：固定总 key 数，扫描 G=1/2/4/8/16；报告消息数、最慢 group latency 和 partial-result 时间。
    • +
  • 验证 Coordinator 停止 60 秒时稳定 Get/Put 的 RPC 数和时延分布不发生变化。
    • +
  • 验证 lease/hotness 更新、TaskEnvelope 和 ResourceView 上报不出现在应用请求 trace 的同步 critical path。
    • +
+ +

7. 控制路径流程分析

+

7.1 MasterNode 加入集群

+ 
+1. New MasterNode starts with node_id and rpc_address.
+2. It registers membership lease in HA Backend.
+3. Coordinator observes the new node and marks it JOINING.
+4. Coordinator publishes a new ClusterView including the node but assigns no MasterGroup replica yet.
+5. After health check and warmup pass, node becomes ACTIVE.
+6. Coordinator adds it to selected MasterGroups as LEARNER.
+7. After snapshot/replay catches up, each group promotes the learner to VOTER or PRIMARY candidate.
+8. Coordinator may then generate a plan to move SlotGroups between MasterGroups.
+
+ +

+ 加入过程不影响已有 slot 的前台读写。只有当 slot group 迁移进入 cutover 时，相关 slot 的客户端会看到短暂 MOVED/ASK。 +

+ +

7.2 MasterNode 优雅下线

+ 
+1. Operator marks MasterNode DRAINING.
+2. Coordinator stops placing new group replicas or primaries on this node.
+3. For every affected MasterGroup, add and catch up a replacement learner.
+4. Transfer primary leadership away, then remove this node from group membership.
+5. Only if group-level load remains imbalanced, move SlotGroups between groups in small batches.
+6. When the node carries no group replica, mark it INACTIVE and stop the process.
+
+ +

+ P99.9 控制点：drain 以小批量迁移执行；当前台 P99.9 超阈值时迁移自动暂停；不做全节点一次性冻结。 +

+ +

7.3 扩容 Rebalance

+ 
+1. Coordinator collects load:
+   - per slot group QPS
+   - key count / metadata bytes
+   - foreground P99.9
+   - migration backlog
+   - resource pressure
+
+2. Coordinator selects candidate slot groups:
+   - avoid hottest slot groups first
+   - prefer large imbalance but low active QPS groups
+   - limit concurrent groups
+
+3. Coordinator starts migration:
+   source -> snapshot copy -> incremental replay -> short cutover -> cleanup
+
+4. Coordinator observes P99.9 guard:
+   if P99.9 or queue depth exceeds threshold: reduce budget or pause migration
+
+5. Repeat until target balance reached.
+
+ +

7.4 缩容 Rebalance

+ 
+1. Operator marks nodes to remove as DRAINING.
+2. Coordinator computes target placement excluding DRAINING nodes.
+3. Slot groups migrate away in priority order:
+   - cold / low QPS slot groups first
+   - hot slot groups during low-traffic windows
+4. If remaining capacity is insufficient, Coordinator rejects shrink plan.
+5. After migration completes, DRAINING node is removed.
+
+ +

+ 缩容比扩容更容易造成尾延迟，因为目标节点承接更多负载。必须先做容量校验和 P99.9 预算校验，不能只看 slot 数是否均衡。 +

+ +

7.5 Slot Group 迁移

+ 
+Plan:
+  Coordinator chooses source MasterGroup, target MasterGroup, slot_group_id, migration_budget.
+
+Prepare:
+  Target group primary creates empty slot group in IMPORTING state.
+  Source group primary marks slot group MIGRATING_SOURCE and records start_oplog_offset.
+
+Snapshot Copy:
+  Source scans metadata in bounded batches.
+  Target group replicates and commits imported batches but does not serve normal requests yet.
+
+Incremental Replay:
+  Source streams OpLog after start_oplog_offset.
+  Target group commits replay and reports committed replay_lag.
+
+Cutover:
+  Source briefly blocks writes for the slot group.
+  Source commits the final OpLog tail and emits a cutover position.
+  Target proves that the cutover position is committed by its replication mode.
+  Coordinator CAS-updates owner_master_group_id and increments assignment_generation with a fencing token.
+  Source group returns MOVED for new requests.
+  Target group serves requests with the new assignment generation.
+
+Cleanup:
+  Source keeps tombstone for late requests, then releases old metadata.
+
+ +

7.6 MasterNode 故障与 MasterGroup Failover

+ 
+1. HA Backend lease expires or health checks fail.
+2. Coordinator marks node SUSPECT, then UNAVAILABLE after quorum/lease confirmation.
+3. QUORUM group elects a replica holding the committed prefix; ASYNC_STANDBY group requires Coordinator-authorized promotion and reports possible RPO loss.
+4. New primary proves its commit/replay position and obtains a higher group term/fencing token.
+5. Coordinator publishes the new primary endpoint and term; slot owner and assignment_generation remain unchanged.
+6. Clients receive NOT_PRIMARY/STALE_TERM or refresh view after RPC deadline.
+7. New primary serves foreground traffic; groups without quorum remain unavailable instead of accepting split-brain writes.
+
+ +

+ P99.9 控制点：故障检测不等待长 RPC；客户端使用短 deadline；failover 以 MasterGroup 为粒度并可并行；replica 持续 replay，避免切换后大规模恢复。组内切主不递增 assignment_generation，只有 SlotGroup 改属另一个 MasterGroup 时才递增。 +

+ +

7.7 Coordinator 故障

+ 
+1. Active Coordinator lease expires in HA Backend.
+2. Standby Coordinator competes for coordinator lease.
+3. New Coordinator reads persisted ClusterView and migration states.
+4. It reconciles Master reports.
+5. Incomplete migration is either resumed or rolled back.
+6. Foreground metadata requests continue using last stable ClusterView.
+
+ +

+ Coordinator 故障不应影响稳定 slot 的读写，也不阻止具备 quorum 的 MasterGroup 完成组内选主。受影响的是新的扩缩容计划、跨组迁移、primary endpoint 发布和后台预算更新。 +

+ +

7.8 资源压力与 Admission Control

+ 
+1. Storage clients report segment usage and health.
+2. MasterGroup primaries report allocation failures and queue depth.
+3. Coordinator computes cluster pressure level.
+4. Coordinator publishes ResourceView and BackgroundBudget.
+5. MasterGroup primaries adjust placement, eviction/offload speed, and admission policy.
+6. If resources remain insufficient, PutStart fails fast with a precise error.
+
+ +

+ P99.9 控制点：资源不足时不能让 PutStart 在 Master 内反复扫描和等待；应快速失败、降级 replica 数，或交给上层重试。 +

+ +

7.9 冷热分级任务

+ 
+Get path:
+  GetReplicaList observes LOCAL_DISK-only hot key
+  -> enqueue promotion task
+  -> return current readable replica immediately
+
+Background path:
+  Storage client heartbeat pulls promotion/offload tasks
+  -> executes data movement
+  -> NotifyPromotionSuccess / NotifyOffloadSuccess
+  -> slot owner commits metadata transition
+
+ +

+ P99.9 控制点：冷热任务必须异步化；前台读不等待 promotion 完成；Coordinator 只调节任务预算，不参与单对象决策。 +

+ +

8. P99.9 稳定性设计

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
设计点要求原因
Coordinator 非热路径正常 Get/Put 不访问 Coordinator避免把 Coordinator 变成新的尾延迟来源
前台 RPC 优先级MasterNode 按 group 区分 foreground queue 和 background queue迁移和扫描不能挤占客户请求
短锁和分片锁对象状态锁限定在 slot group 或 key 粒度避免全 shard 锁导致 P99.9 抖动
迁移预算限制同时迁移 slot group、snapshot 带宽和 replay QPS扩缩容期间稳定前台时延
快速失败资源不足、fencing token 过期、owner 错误时快速返回明确错误避免请求排队等待不可满足条件
客户端 deadline每个 Master RPC 设置 deadline 和 bounded retry控制跨 shard Batch 的尾部等待
自动保护闭环当 P99.9 超阈值时自动降低后台预算把客户时延优先级置于扩缩容速度之上

9.4 物理视图

+

+ 物理视图描述部署拓扑。 +

+ 
+Rack / AZ A:
+  MasterNode A: G1 primary, G2 voter, G3 voter
+  Storage Clients
+
+Rack / AZ B:
+  MasterNode B: G2 primary, G1 voter, G3 voter
+  Storage Clients
+
+Rack / AZ C:
+  MasterNode C: G3 primary, G1 voter, G2 voter
+  Storage Clients
+
+Coordinator:
+  active + standby deployment
+  backed by HA Backend lease
+
+HA Backend:
+  odd-number quorum deployment if using etcd-like backend
+
+ +

+ 同一 MasterGroup 的 replicas 应跨故障域部署，并为任一节点故障后的 primary 提升预留容量。Coordinator active/standby 也应跨节点部署，但 Coordinator 不承载热路径，因此其资源规格可以小于 MasterNode。 +

+ +

9.5 场景视图

+

+ 场景视图对应架构的 +1，用关键用例验证其他四个视图是否闭合。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
场景参与组件关键判断
正常 GetClient、owner MasterGroup primary不访问 Coordinator；单 group primary 完成并按复制模式提交。
正常 PutClient、owner MasterGroup primary、Storage ClientMaster 使用本地 ResourceView；不阻塞等待 Coordinator。
扩容Coordinator、Source Group、Target Group、Client迁移按预算执行；cutover 通过 assignment generation 和 MOVED 完成。
缩容Coordinator、Draining MasterNode、affected MasterGroups先容量校验，再低 QPS slot group 优先迁移。
MasterNode 故障affected MasterGroups、Coordinator、HA Backend、Client各组独立提升 term 和 primary；slot owner/assignment_generation 不变。
Coordinator 故障HA Backend、Standby Coordinator、MasterGroups稳定 slot 前台读写继续；迁移编排暂停后恢复。
P99.9 抖动MasterGroups、CoordinatorLatencyGuard 降低后台任务预算，必要时暂停迁移。

11. 新开发特性与独立验收清单

+

+ 本节是可直接进入需求和测试系统的 feature backlog。每个特性必须能单独部署或使用 fake/mock 依赖进行验收； + “代码已合入”“接口已定义”不算验收完成。除特别说明外，所有故障用例都必须有自动化测试，所有状态变化都必须暴露指标和结构化日志。 +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ID / 特性交付边界独立验收标准
F01
稳定 Slot Hash		定义 tenant-aware hash、16384 slots、跨语言测试向量和版本号；不包含远程路由。至少 C++/Python 对 10,000 个固定输入产生完全一致的 slot；进程重启、编译优化级别变化后结果不变；非法 hash version 明确报错。
F02
ClusterView 数据模型与持久化		序列化 MasterNode、MasterGroup、SlotGroupOwner、ClientControlOwner 及各自 fencing 字段；提供内存和 HA Backend adapter。view 可 round-trip；CAS 拒绝旧 view_revision；进程重启恢复结果一致；未知字段可前向兼容；损坏记录不被静默接受。
F03
ClusterView Watch		提供全量读取、增量 watch、断线续传和 compact 后回退全量读取。连续提交 1,000 次 view 更新，watcher 不丢失且顺序一致；任意位置断线重连后收敛到最终 view；慢 watcher 不阻塞发布者。
F04
客户端 Group 路由		实现 key -> slot -> SlotGroup -> MasterGroup -> primary endpoint，校验 group term 和 assignment_generation。使用 fake view 将全量 slot 路由到预期 endpoint；收到 NOT_PRIMARY、STALE_TERM、MOVED 后在 bounded retry 内刷新并成功；Coordinator 不出现在正常 Get/Put 调用链。
F05
Batch Regroup		按 MasterGroup 并行拆分 Batch，并按输入顺序合并逐 key 结果。混合至少 3 个 group、重复 key 和部分失败时，输出顺序及错误一一对应；一个 group 超时不取消已完成 group；总等待不超过配置 deadline。
F06
MasterNode Membership		实现 node register、lease renew、SUSPECT、UNAVAILABLE、DRAINING、INACTIVE 状态机。fake clock 下验证每个合法转换；lease 到期在规定窗口内标记 UNAVAILABLE；旧 node_incarnation_id 无法续租或覆盖重启后的新实例；非法跳转被拒绝并记录原因。
F07
MasterGroup 单副本运行时		一个 MasterNode 承载多个逻辑 group；每组隔离元数据、OpLog、snapshot、指标和 RPC queue。单进程启动至少 32 个 group 并写入相同 key，各组数据互不串扰；单组 snapshot/restart 恢复不影响其他组；可按 group 查询 CPU、队列和 metadata bytes。
F08
Group Term 与写 Fencing		所有写请求携带 master_group_id + group_term；旧 primary 无法提交写。将 term 从 N 提升到 N+1 后，term=N 的 Put/Remove/任务完成通知全部返回 STALE_TERM；并发压力下旧 term 成功提交数为 0；读写错误包含 current term。
F09
QUORUM Group 复制与选主		实现 3+ voter 的日志复制、commit index、leader election 和 learner catch-up。3 节点组在任意 1 节点故障后已确认写不丢失并恢复服务；隔离旧 primary 后不能形成双写；失去多数派时拒绝写；learner 追平后状态 hash 与 leader 一致。
F10
ASYNC_STANDBY 模式		实现异步 OpLog replay、replay position、显式提升和 RPO 暴露；不宣称 quorum 语义。注入 replay lag 后指标准确反映差值；提升时返回可能丢失的 position/bytes；未取得 fencing token 的 follower 不可提升；文档/API 明确返回当前 ReplicationMode。
F11
Group Placement 与成员变更		Coordinator 依据故障域和容量放置 replicas，采用 learner-add/catch-up/promote/remove 流程。输入多机架拓扑时同组 replicas 不共故障域；目标不满足约束时计划被拒绝；成员变更中断后可恢复或回滚；任一时刻不产生两个有效 primary。
F12
SlotGroup 静态分配		把 16384 slots 完整且无重叠地分配给多个 MasterGroup，并在服务端强制校验归属。覆盖检查证明每个 slot 恰好一个 owner；非 owner 请求返回包含目标 group 的 MOVED；旧 assignment_generation 返回 STALE_ASSIGNMENT；组内切主不改变 assignment_generation。
F13
SlotGroup 在线迁移		实现 IMPORTING、snapshot copy、committed replay、cutover fencing、MOVED 和 source cleanup。持续并发 Put/Get 时迁移一个 SlotGroup，cutover 后 source/target 对象状态 hash 一致、已确认写零丢失、同一 key 无双 owner；任一阶段 kill/restart 均能恢复或安全回滚。
F14
Segment Control-Owner 路由		按 client_id 将同一 Storage Client 的全部 segments 绑定到一个 MasterGroup，支持 control_generation 和 heartbeat redirect。同一 client 的不同介质 segment 始终落到同组；组内切主只改变 endpoint/term；跨组迁移只提升 control_generation；旧 control owner 无法接受新 heartbeat 或控制写。
F15
跨组任务投递		对象 owner 提交 TaskIntent，至少一次投递到 segment control-owner group，并以 task_id 幂等完成。在投递前、投递后、执行后分别注入崩溃，最终任务恰好产生一次对象状态变化；重复消息不重复分配/释放；任一 term/generation 过期时刷新路由而不是执行。
F16
Resource Capability 与 Telemetry		上报容量、读写带宽、IOPS、并发度、延迟桶、实时使用量、reserved、队列及采样时间。fake Storage Client 上报后 ResourceView 在时限内可见；同一 segment_incarnation 下较小 sample_seq 的样本不会覆盖新样本；超过 freshness 阈值的 segment 被标为 stale；读/写及不同对象大小桶不被合并。
F17
多维 Reservation		以 lease/CAS 原子预留 bytes、bandwidth、IOPS，支持 TTL、幂等键、commit 和 revoke。100 个并发请求不会使任一资源维度超卖；相同幂等键只产生一份 reservation；TTL 后资源可回收；commit/revoke 重复调用结果稳定。
F18
版本化 PlacementPolicy		实现硬约束过滤、可插拔评分、Top-K 有界 reserve 和 ScoreBreakdown；首版使用确定性加权评分。容量不足、故障域冲突和能力不匹配的候选永不入选；固定快照与 policy version 输出完全可重放；每次决策可解释各分项；reserve 尝试不超过配置 K。
F24
Delegated Extent Lease		Storage Client allocator 批量租出互不重叠的 extent range 和多维预算；MasterGroup 在租约内本地分配、后台续租和归还。并发向两个 group 发放租约时 extent 零重叠；旧 segment_incarnation/control_generation 或过期 lease 无法 commit；正常 PutStart 不产生 allocator RPC；耗尽时有界触发后台批量 refill，当前请求快速失败而不无限等待。
F19
Replica Read Selection		在已有 replicas 中根据健康、实时队列、带宽、时延和 locality 排序，不改变持久 placement。注入慢副本后新读流量在观测窗口内转移，恢复后按 hysteresis 回切；无健康副本时返回明确错误；选择变化不产生数据迁移或 metadata ownership 变化。
F20
BackgroundBudget 与 LatencyGuard		分别限制迁移、snapshot、offload、promotion、eviction；根据前台 P99.9 和队列闭环降速/恢复。压测使 P99.9 超阈值后一个控制窗口内降低预算，连续健康窗口后渐进恢复；前台流量不经过 Coordinator；预算过期时采用保守默认值。
F21
Coordinator HA		active/standby lease、fencing token、持久计划恢复；不承担 MasterGroup 日志提交。双实例竞争时最多一个可提交 view；kill active 后 standby 恢复未完成迁移状态；切换期间稳定 group 的 Get/Put 持续成功；旧 Coordinator CAS 全部失败。
F22
可观测性与一致性审计		提供 per-node/group/slot/client/segment 指标、结构化事件和只读审计 API。自动审计能检测 slot 重叠/缺口、同 group 双 primary、replica 跨域违规、stale fencing token 和 reservation 泄漏；健康集群误报为 0；每个异常可定位到实体 ID 和 view revision。
F23
故障注入与兼容性测试框架		可注入进程退出、网络分区、延迟、丢包、磁盘错误、时钟推进和旧版本客户端；输出确定性报告。CI 可独立复现指定 seed；至少覆盖旧 primary 隔离、迁移中断、watch 断线、重复任务、过期 ResourceView；失败报告包含 seed、时间线和最终不变量检查。
+ +

11.1 通用 Definition of Done

+
    +
  • 每项特性有独立 feature flag 或明确的启用条件，关闭时不改变现有单 Master 行为。
    • +
  • 新增持久化结构必须包含 schema/version，并至少验证一次旧版本读取新版本中已知字段的兼容路径。
    • +
  • 所有重试均有 deadline、最大次数和幂等键；验收不得依赖无限等待或人工查看日志。
    • +
  • 性能相关特性必须同时报告吞吐、P50、P99、P99.9 和资源占用，并保存可比较的基线。
    • +
  • 验收报告必须记录代码版本、配置、拓扑、随机 seed、开始/结束时间和不变量检查结果。
    • +
+ +

11.2 依赖关系与并行开发边界

+ 
+基础契约： F01 -> F02 -> F03
+客户端：   F01 + F02 -> F04 -> F05
+Group：    F02 -> F07 -> F08 -> {F09 | F10} -> F11
+Slot：     F04 + F07 -> F12 -> F13
+Segment：  F02 + F07 -> F14 -> F15
+资源调度： F16 -> F17 -> {F18, F24}; F18 + F24 -> F19
+保护闭环： F16 -> F20
+系统 HA：  F03 + F11 + F13 -> F21
+质量体系： F22、F23 从第一阶段开始，并为其他特性提供验收 harness
+
+

+ 箭头表示生产集成依赖，不表示验收必须串行。例如 F04 可用 fake ClusterView 验收，F15 可用两个内存 MasterGroup + 和 fake heartbeat 验收，F18 可使用固定 ResourceView 快照验收。这样各团队可以并行开发，同时保持每项交付可独立判定成功或失败。 +

+ +

12. 演进计划

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
阶段内容收益
阶段一单 Master 暴露 16384 slot 的 ClusterView；客户端实现 slot 计算和路由缓存。不改变部署即可验证客户端路由逻辑。
阶段二多个单副本 MasterGroup 静态分配 SlotGroup；Batch regroup；MOVED/STALE_ASSIGNMENT。核心元数据请求横向扩展。
阶段三引入轻量 Coordinator，管理 view、resource summary 和后台预算。为扩缩容、P99.9 保护和资源协同打基础。
阶段四实现 slot group 在线迁移、snapshot copy、incremental replay、ASK/MOVED cutover。支持在线扩缩容和 rebalance。
阶段五为 MasterGroup 增加 replica、term、组内选主与 fencing；实现 Coordinator active/standby。降低故障影响范围，提高可用性。

13. 风险与约束

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
风险影响缓解措施
Coordinator 被误用到热路径成为新的 P99.9 瓶颈接口约束：Get/Put 不调用 Coordinator；客户端只周期性或按错误刷新 view。
ResourceView 过期PutStart 选择到高水位或不可用 segmentallocator lease/CAS 二次确认；失败快速换候选或返回错误。
迁移 replay lag 过大cutover 窗口变长lag 超阈值时暂停新迁移，降低前台写入冻结时间。
跨 slot Batch 尾延迟最慢 shard 拉高整批响应per-shard deadline、partial result、bounded retry。
热点 slot group单 shard 局部热点rebalance 避免迁移最热 group；必要时支持 hash tag 约束和 key-level split。
Coordinator split-brain生成冲突 view 或迁移计划Coordinator lease + fencing token；所有 view 更新通过 HA Backend CAS。
term、assignment_generation、control_generation 混用普通切主触发无谓 slot 迁移，或旧 primary/旧 control owner 未被正确隔离分别校验组内领导权、SlotGroup 归属和 client 控制归属；协议字段与错误码独立。
多个 group replicas 共置于同一故障域单节点或单机架故障同时失去 quorumgroup placement 使用反亲和约束，并在部署前做 N-1 failover capacity 校验。
异步主备被当作强一致复制故障提升后丢失已确认写或产生分叉ClusterView 明确暴露 ReplicationMode、commit/replay position 和可承诺的 RPO；需要 RPO=0 时使用 quorum 提交。
+ +

14. 最终建议

+
+

+ 轻量 Coordinator 路线是 Mooncake 分布式元数据面的推荐落地方案：它保留 Redis Cluster 风格的客户端直连和 slot redirect，避免中心化热路径；同时补足 Mooncake 相比 Redis 多出来的物理资源管理、冷热分级、slot 迁移限速和 P99.9 自动保护能力。 +

+
+ +

MC_LOG 捕获当前 trace：每条 `MC_LOG` / `MC_VLOG` 在构造 `AsyncLogMessage` 时立即捕获当前 trace_id，并随 `LogEntry` 放入异步日志队列。后台日志线程只负责输出已经捕获好的 trace_id。 +4. 跨线程提交前显式捕获：当执行流要进入线程池或 worker 队列时，提交线程先调用 `CurrentTraceId()` 取出当前 trace_id，并把它放进任务对象或 lambda 捕获列表。 +5. 工作线程恢复上下文：worker 取出任务后创建 `ScopedTraceId trace(task.trace_id)` 或 `ScopedTraceId trace(trace_id)`，让该任务执行期间的所有 `MC_LOG` 都继续带原始请求的 trace_id。 +6. 任务结束自动恢复：worker 任务作用域结束后 `ScopedTraceId` 析构，恢复该线程之前的 trace_id，通常恢复为 `0`，后续空闲、清理或下一任务日志不会串到刚完成的请求上。 + +典型同步链路： + +``` +RealClient::get_buffer + -> ScopedTraceId(NewTraceId()) + -> RealClient::get_buffer_internal + -> Client::Get / TransferSubmitter + -> MC_LOG 捕获 CurrentTraceId() +``` + +典型异步链路： + +``` +RealClient::put + -> ScopedTraceId(NewTraceId()) + -> client_service 提交异步任务前 CurrentTraceId() + -> write_thread_pool_.enqueue(..., trace_id) + -> worker lambda 内 ScopedTraceId(trace_id) + -> StoreObject / PutEnd 相关 MC_LOG 继续使用同一 trace_id +``` + +典型传输任务链路： + +``` +TransferSubmitter::submitTransfer + -> MemcpyTask(..., CurrentTraceId()) + -> MemcpyWorkerPool::workerThread + -> ScopedTraceId(task.trace_id) + -> memcpy / GPU copy 相关 MC_LOG 使用原始 trace_id + +TransferSubmitter::submitFileReadOperation + -> FilereadTask(..., CurrentTraceId()) + -> FilereadWorkerPool::workerThread + -> ScopedTraceId(task.trace_id) + -> LoadObject 相关 MC_LOG 使用原始 trace_id +``` + +**异步任务传播：** + +- `MemcpyTask` 和 `FilereadTask` 携带 `trace_id` 字段 +- `client_service.cpp` 中异步 `StoreObject + PutEnd` 的线程池 lambda 通过捕获列表携带 `trace_id` +- 工作线程取出任务后通过 `ScopedTraceId trace(task.trace_id)` 或 `ScopedTraceId trace(trace_id)` 恢复上下文 +- 确保异步路径的日志可关联到原始操作 + +**日志格式：** + +``` +I0527 14:30:00.123456 12345 real_client.cpp:2682] trace_id[123456789abcdef0] get_breakdown key[k1] ... +I0527 14:30:00.123789 12345 real_client.cpp:3600] trace_id[none] Cleaning up ... +``` + +### 9.3 FlushAsyncLogs + +调用 `mooncake::logging::FlushAsyncLogs()` 可手动刷出异步队列中所有待输出日志，内部会等待队列为空且无活跃写入后调用 `google::FlushLogFiles(google::INFO)`。 + +--- + +## 10. `client_create_breakdown` 日志 + +来源：`client_service.cpp::Client::Create` + +记录 Client 对象创建过程各阶段耗时。有两种变体： + +### 10.1 RPC-only 模式（`protocol == "rpc_only"`） + +``` +client_create_breakdown protocol[rpc_only] connect_master_us[{t1}] storage_config_us[{t2}] init_transfer_engine_us[0] init_transfer_submitter_us[0] total_us[{t5}] +``` + +### 10.2 完整模式 + +``` +client_create_breakdown protocol[{p}] connect_master_us[{t1}] storage_config_us[{t2}] init_transfer_engine_us[{t3}] init_transfer_submitter_us[{t4}] total_us[{t5}] +``` + +### 字段说明 + +| 字段 | 含义 | +|------|------| +| `protocol` | 传输协议：`rdma` / `tcp` / `ub` / `ascend` / `cxl` / `rpc_only` 等 | +| `connect_master_us` | 连接 Master 服务耗时（微秒），含 HA 视图读取（如启用） | +| `storage_config_us` | 获取存储配置耗时（微秒），含 GetStorageConfig 或回退 GetFsdir | +| `init_transfer_engine_us` | 初始化传输引擎耗时（微秒），rpc_only 模式为 0 | +| `init_transfer_submitter_us` | 初始化传输提交器耗时（微秒），rpc_only 模式为 0 | +| `total_us` | `Client::Create` 总耗时（微秒），从函数入口到返回 | + +--- + +## 11. 传输任务层日志 + +来源：`mooncake-store/src/transfer_task.cpp` + +记录传输任务执行过程中的关键步骤耗时。 + +### 11.1 `transfer_future_wait` + +``` +transfer_future_wait first_wait[{0/1}] ready_before_wait[{0/1}] strategy[{int}] wait_us[{us}] result[{code}] +``` + +记录等待传输 Future 完成的过程。 + +| 字段 | 含义 | +|------|------| +| `first_wait` | 是否为进程首次调用 wait：`1` 首次，`0` 后续（用于区分首次建连开销） | +| `ready_before_wait` | wait 前传输是否已完成：`1` 已完成（无需等待），`0` 需要等待 | +| `strategy` | `TransferFuture` 的传输策略整数值 | +| `wait_us` | 等待耗时（微秒） | +| `result` | 传输结果：`OK` 表示成功，其他为错误码 | + +### 11.2 `open_segment_breakdown` + +``` +open_segment_breakdown endpoint[{addr}] open_segment_us[{us}] status[{0/-1}] +``` + +记录打开远端 Segment（建立传输连接）的耗时。 + +| 字段 | 含义 | +|------|------| +| `endpoint` | 传输引擎端点地址字符串 | +| `open_segment_us` | `openSegment()` 调用耗时（微秒） | +| `status` | 结果：`0` 成功，`-1` 失败（`ERR_INVALID_ARGUMENT`） | + +### 11.3 `submit_transfer_breakdown` + +``` +submit_transfer_breakdown first_transfer[{0/1}] batch_id[{id}] request_count[{n}] alloc_batch_id_us[{us}] submit_transfer_us[{us}] status[{0/err}] +``` + +记录提交批量传输请求的耗时拆分。 + +| 字段 | 含义 | +|------|------| +| `first_transfer` | 是否为首次提交传输：`1` 首次，`0` 后续 | +| `batch_id` | 批量传输 ID | +| `request_count` | 本次提交的传输请求数量 | +| `alloc_batch_id_us` | 分配 batch ID 耗时（微秒） | +| `submit_transfer_us` | 提交传输请求耗时（微秒） | +| `status` | 提交结果：`0` 成功，其他为 gRPC 状态码 | + +--- + +## 12.

This produced both: error: definition of '...' is not in namespace enclosing 'mooncake::Environ' [-fpermissive] error: redefinition of '...' Fix: keep a single copy of each method, and place it in the mooncake namespace (after the closing brace of the anonymous namespace at line 112, before Environ::Get() at line 152) so the definitions resolve to the class members declared in environ.h. --- mooncake-common/src/environ.cpp | 114 +++++++++++--------------------- 1 file changed, 38 insertions(+), 76 deletions(-) diff --git a/mooncake-common/src/environ.cpp b/mooncake-common/src/environ.cpp index b49f963401..b6b5b4e9cf 100644 --- a/mooncake-common/src/environ.cpp +++ b/mooncake-common/src/environ.cpp @@ -47,82 +47,6 @@ int ReadInt(const EnvironSource& source, const char* name, int default_value) { return default_value; } -size_t Environ::GetOffloadRpcThreadNum(size_t default_value) const { - const size_t value = GetSizeT("MC_OFFLOAD_RPC_THREAD_NUM", default_value); - return value == 0 ?

Default behavior is unchanged (best-effort with partial-allocation metric/log from the previous commit). Also fixes the ported PutStartPartialAllocationIsObservable test to use the plain string tenant id, since this branch has no TenantId type. Tested: master_service_test 131/131 passed, master_metrics_test 10/10 passed (WSL, Debug build). * [Store] Add test covering strict vs best-effort dual-replica degradation Covers the exact behavior difference of strict_replica_allocation with the production baseline config (replica_num=2, no NoF): when only one replica is allocatable (single mounted segment), best-effort silently degrades to one replica (with partial-allocation metric), while strict mode fails with NO_AVAILABLE_HANDLE and counts an allocation failure. --------- Co-authored-by: Chuang Zhang --- mooncake-store/include/master_config.h | 19 ++++ mooncake-store/include/master_service.h | 5 + mooncake-store/src/master.cpp | 12 +++ mooncake-store/src/master_service.cpp | 30 ++++-- mooncake-store/tests/master_service_test.cpp | 100 +++++++++++++++++++ 5 files changed, 160 insertions(+), 6 deletions(-) diff --git a/mooncake-store/include/master_config.h b/mooncake-store/include/master_config.h index 2940d0e59d..1e67014f47 100644 --- a/mooncake-store/include/master_config.h +++ b/mooncake-store/include/master_config.h @@ -127,6 +127,11 @@ struct MasterConfig { size_t offloading_queue_limit = 50000;

AddReplica now dedups by client_id: refresh the existing replica owned by the same client (idempotent re-offload / restart re-register) or append a new one, so each offloading node keeps its own LOCAL_DISK replica.

From d5c9e305aabb21089f0e612462899bde301c3ad3 Mon Sep 17 00:00:00 2001 From: yyyuanhao426-hash Date: Sat, 1 Aug 2026 23:10:14 +0800 Subject: [PATCH 196/248] Urma mode (#18) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(ub): 支持多路径传输的chip亲和性 - 在Transport::Slice::UbContext中增加src_chip_id和dst_chip_id字段 - 新增内存位置解析工具函数：parseCpuNumaNode、resolveBufferNumaNode、numaNodeToChipId - UbContext新增multipath配置支持，从全局配置读取urma_bonding_multipath - 在UbTransport中根据buffer位置信息计算并设置slice的chip_id - 修改UrmaEndpoint::submitPostSend，根据multipath配置选择使用bondp_jfs_wr_t或urma_jfs_wr_t - 当启用多路径时，设置bonding模式为BALANCE以实现负载均衡 * style: 使用完全限定类型名 std::string 替换 string 使用 std::string 替代 using 指令引入的 string 类型，以提高代码清晰度和可维护性。 * feat(ub): 添加 NUMA 亲和性支持以提升跨 NUMA 传输性能 - 新增配置项 `ub_numa_affinity`，通过环境变量 `MC_UB_NUMA_AFFINITY_ENABLE` 控制，用于启用 UB 传输的 NUMA 亲和性优化。 - 当启用时，存储层将全局段按 NIC 所属的 NUMA 节点拆分为多个独立段，每个段绑定到特定 NUMA 节点（location="cpu:N"），使主控能按 NUMA 进行负载均衡。 - 传输引擎在提交任务时，会根据源/目标缓冲区的 NUMA 节点计算对应的 chip_id，实现数据传输的 NUMA 本地化。 - 改进 `numaNodeToChipId` 函数，优先读取 sysfs 真实拓扑（physical_package_id）进行映射，失败时回退到原有的启发式方法，确保兼容性。 * feat(ub): 为单NUMA缓冲区预计算并发布chip_id 在UB传输中，为单NUMA（"cpu:N"）缓冲区在注册时预计算其chip_id并发布到元数据中。消费者端在需要NUMA亲和性时，可直接读取此预计算值，避免每次切片都重新解析缓冲区名称来计算NUMA节点。对于多NUMA段（"segments:..."）或旧版本对等方未提供此字段的情况，保持向后兼容，chip_id为-1并回退到原有的解析逻辑。 * fix(transport): 修正 NUMA 亲和与多路径绑定的条件判断 原代码使用 multipath 标志控制 chip 亲和（bondp_jfs_wr_t）的提交路径，但 chip 亲和实际应由 NUMA 亲和开关（numa_affinity）控制。多路径绑定（multipath）是设备级设置，在 openDevice 阶段决定。此次修改将条件变量从 multipath 更正为 numa_affinity，确保逻辑正确。 同时更新了 real_client.cpp 中相关注释，阐明 UB 的 NIC-NUMA 节点挂载策略是自动的，独立于 chip-id 计算和多路径绑定开关。 * feat(ub): 支持基于 NUMA 节点总数的内存分布 新增 GetNumaNodeCount 方法以获取系统 NUMA 节点总数，用于 UB 协议下的内存段挂载策略。现在内存将均匀分布在所有 NUMA 节点上，而非仅限带有 NIC 的节点，这解决了在单绑定设备（NUMA=-1）场景下的问题。同时修复了 ubcore "numa" 属性十六进制解析错误。 * feat(transport): 添加NUMA亲和性调试日志 - 在ub_transport.cpp和ub_context.cpp中添加VLOG(2)级别调试日志，记录NUMA节点解析结果和芯片ID - 在urma_endpoint.cpp中添加bonding模式配置的INFO日志和提交发送时的VLOG(2)调试日志 - 重构NUMA节点解析代码以提高可读性 * perf: 优化 NUMA 亲和性日志以减少性能开销 - 将详细 NUMA 映射信息采样频率从每次记录改为每 10000 次记录一次 - 在 ub_transport.cpp、urma_endpoint.cpp 和 ub_context.cpp 中引入原子计数器进行采样控制 - 改进 NumaChipMap 的日志格式，使其更结构化且包含完整映射信息 - 添加操作类型（READ/WRITE）到采样日志中以增强可调试性 - 对于非 NUMA 亲和模式，仅首次记录禁用状态以避免日志冗余 这些修改减少了高频日志输出对性能的影响，同时保留了足够的调试信息。 * fix(urma): 添加读写锁保护共享数据结构并发访问 添加 RWSpinlock 保护 import_tseg_map、remote_seg_list_ 和 imported_seg_list_，防止多线程并发调用 retrieveRemoteSeg 时发生数据竞争。在 retrieveRemoteSeg 中实现读-复制-更新模式：先获取读锁进行快速路径查找，未命中时获取写锁，重新检查后执行导入操作并原子地更新共享列表和映射。 * Revert "fix(urma): 添加读写锁保护共享数据结构并发访问" This reverts commit dfff34a61cacb2e79fd2348c3ba91b3f2527ca62. * fix(urma): 在submitPostSend中修正语法错误 将多余的右括号替换为分号，以修复编译错误。 * fix(urma): 修复多路径关闭时的绑定模式设置并强制本机传输同芯片ID 多路径关闭时，显式设置绑定模式为 STANDALONE/PORT 以替代隐式默认值，避免未定义行为。 同时，在提交发送请求时，强制将目标芯片ID设置为源芯片ID，以解决本机两端芯片ID不同时无法跨芯片传输的问题。 * feat(ub_allocator): 新增 NUMA 节点绑定的内存分配函数 添加 ub_allocate_memory_onnode 函数，允许在指定 NUMA 节点上分配内存，同时保持与 URMA 注册的兼容性。在 RealClient 中，当启用 UB 协议且配置了多 NUMA 节点时，使用此函数为每个节点分配独立的内存段，以实现 NUMA 亲和性，避免使用 mmap+mbind 导致的 URMA 注册失败问题。 * refactor(kunpeng_transport): 简化NUMA节点解析，移除偏移量计算 UB缓冲区以NUMA节点为单位独立分配，其名称已直接包含 CPU 编号，无需再根据偏移量解析段信息。改用 parseCpuNumaNode 直接解析名称，去除 resolveBufferNumaNode 的重载调用。 * feat(urma): 支持多路径并修复发送chip_id错误 * fix(urma): 修复跨芯片传输时 src/dst 芯片 ID 备注错误，并统一失败计数 * refactor: 移除未使用的 resolveBufferNumaNode 函数 --------- Co-authored-by: Saturday Co-authored-by: Chuang Zhang --- mooncake-store/include/client_service.h | 4 + mooncake-store/src/client_service.cpp | 132 +++++++++++- mooncake-store/src/real_client.cpp | 85 +++++++- mooncake-transfer-engine/include/config.h | 5 + .../include/memory_location.h | 12 ++ .../include/transfer_metadata.h | 5 + .../transport/kunpeng_transport/ub_context.h | 12 +- .../include/transport/transport.h | 2 + .../include/ub_allocator.h | 6 + mooncake-transfer-engine/src/config.cpp | 12 ++ .../src/memory_location.cpp | 144 +++++++++++++ mooncake-transfer-engine/src/topology.cpp | 14 +- .../src/transfer_metadata.cpp | 5 + .../kunpeng_transport/ub_allocator.cpp | 21 +- .../kunpeng_transport/ub_context.cpp | 54 +++++ .../kunpeng_transport/ub_transport.cpp | 49 ++++- .../kunpeng_transport/urma/urma_endpoint.cpp | 201 ++++++++++++------ 17 files changed, 683 insertions(+), 80 deletions(-) diff --git a/mooncake-store/include/client_service.h b/mooncake-store/include/client_service.h index 4917ec30bb..f4ab18fccc 100644 --- a/mooncake-store/include/client_service.h +++ b/mooncake-store/include/client_service.h @@ -635,6 +635,10 @@ class Client { // Return sorted NUMA node IDs that have at least one RDMA NIC.
