The shared `small_write` configuration also makes protocol-specific admission and EC settings unclear. Runtime storage wiring and some Iceberg file handling live in the application crate. This obscures ownership when S3 and table traffic have different scaling and placement needs.

S3 and Iceberg each own their metadata, chunk client construction, write admission, and file/object storage behavior in `crowdb-access-s3` and `crowdb-access-iceberg`.

Make `crowdb-chunk-client` small-write allocation and large-write prefetch take the owning protocol's chunk type. Keep an independently elastic small-write pool per protocol. The type is fixed for one pool or prepared large-write session, including on-demand allocation, rotation, mirror-to-EC conversion, repair, and cleanup. +3. Move S3 foreground client wiring and policy selection from `app/crowdb-access-server` into `crowdb-access-s3`. Move Iceberg foreground client wiring and file-storage policy selection into `crowdb-access-iceberg`. Keep S3 metadata in its S3 library and table/catalog metadata in its Iceberg library. Preserve the separate Iceberg GC client pool when GC is enabled. +4. Give S3 and Iceberg their own small-write and large-write EC, memory, and prefetch settings. Do not require the two EC schemes to match. Large-write EC remains a policy of each write/strip; this requirement does not force all future strips in a chunk to use one EC scheme.

It therefore spends resources on copies that cannot survive a node failure. The large-write path hardcodes EC and its mirror strip writer is incomplete; the small-write path implements mirror I/O separately. Without a deployment-level guard, a protected cluster could accept an unsafe layout when topology shrinks. See [chunk IO](../design/chunkio/design-crowdb-chunkio.md), [chunk placement](../design/chunkdb/design-crowdb-chunkdb.md), and [KV quorum](../design/kv/design-crowdb-kv.md). + +#### Solution + +Production deployment requires at least three voting nodes, with KV and chunk placement capable of continuing after any one node fails. There is no standalone two-node deployment mode. The two surviving nodes of a three-node cluster retain the original three-voter membership and its two-vote Paxos quorum. + +Single-node is an explicit test-only mode. It has one KV server and one voting copy per KV group. Every new chunk strip has 1 MiB logical data capacity and one mirror copy; EC, multiple mirror copies, and mirror-to-EC conversion are disabled. A data error is returned to the caller. This mode provides no data protection and cannot be entered automatically because of missing nodes, failed placement, or quorum loss. + +1. Make the deployment protection mode explicit in startup configuration. Validate the KV replica topology and chunk placement policy against it before serving writes. Reject a production configuration with fewer than three voting nodes, and reject test-only single-node configuration that requests multiple copies or EC. +2. Treat a chunk as a sequence of strips, each with its own logical data capacity and protection layout. The chunk write path advances through strips and delegates block alignment, cross-block writes, mirror duplication or EC encoding, durability, and repair to the selected strip writer. A mirror strip writer must handle the single-copy test layout and protected mirrored layouts. The read path dispatches to the matching strip reader, whose error recovery is layout-specific. +3. Keep foreground write policy in each access library and physical strip I/O in chunk-client. S3 and Iceberg may choose separate policies; neither decides placement or performs EC encoding itself. Existing small-write admission remains independent of the large-write path while sharing strip-level semantics where appropriate. +4. In a healthy production cluster, place each configured layout across failure domains so loss of any one node leaves enough information to read committed data. Reject an EC layout whose per-node shard distribution cannot satisfy that invariant. After one node fails, retain the original protected-cluster identity and quorum. Permit new writes only through a defined degraded layout that fits the two surviving nodes and can later be repaired; never silently allocate a one-copy strip. Recover full placement when capacity returns. + +#### Dependencies + +- R191 supplies protocol-owned chunk types and write policies; this requirement consumes them without merging their small-write pools. +- KV already computes majority quorum from voting members: three voters need two votes, while two voters also need two. This requirement does not change Paxos quorum semantics or introduce a two-voter production profile. +- If protected degraded writes and their repair cannot yet be completed, reject those writes explicitly while preserving readable committed data; do not claim full one-node-failure availability until the write acceptance case passes. + +#### Acceptance + +- Given production configuration with fewer than three voting nodes, start the services; startup rejects it before accepting a write. Given three voters, startup succeeds. Integration test. +- Given a single-node test profile with one KV replica, write and read both small and large objects; every new strip has one 1 MiB mirror copy, and no EC or conversion task is created.

First divergent server error in `crowdb-chunk-kv-server-20260930-020901.967-326637.log`: `chunk KV journal stream append failed error=stream metadata or data is corrupt: stream chunk mirror count differs from configuration`. +- Attempts: initial outage run showed a 503; S3 application logging identified `PutOutcome::Timeout`; S3 library logging located the Chunk-KV operation deadline; `MirrorChunkWriter` geometry fix exposed a stopped ChunkDB range owner; pinning the protected fixture's ChunkDB instance to surviving node 1 exposed the current journal geometry rejection. Each run kept the same old-read/new-write outage acceptance. +- Diagnosis: after a failed three-copy mirror write, the stream rotates to a new two-copy chunk, which is the required protected degraded layout. The writer accepts it, while `lib/crowdb-chunk-stream/src/production_chunk.rs` still compares `mirror.segments.len()` with configured `mirror_copies` and classifies the stream as corrupt. Alternatives are to make journal validation accept persisted protected layouts with at least two distinct copies, or to route journal writes through another recovery path that explicitly records a degraded policy; the first follows the existing degraded allocation contract. Full three-instance ChunkDB range failover and repair after recovery remain unfinished. ## Verification and cleanup diff --git a/lib/crowdb-access-s3/src/streaming.rs b/lib/crowdb-access-s3/src/streaming.rs index adf54f51..dbf177ea 100644 --- a/lib/crowdb-access-s3/src/streaming.rs +++ b/lib/crowdb-access-s3/src/streaming.rs @@ -474,9 +474,12 @@ pub async fn cleanup_after_definite_error( fn classify_publication_error(error: PublicationError) -> PutOutcome { match error { - PublicationError::Store(MetadataStoreError::Client( + timeout @ PublicationError::Store(MetadataStoreError::Client( ClientError::Deadline | ClientError::Transport(_), - )) => PutOutcome::Timeout, + )) => { + tracing::warn!(%timeout, "S3 object publication outcome is uncertain");

The current EC selector checks the maximum fragments on one node against the parity count. That check cannot express a larger failure budget: with six nodes and two allowed failures, `4+2` and `8+4` can survive any two nodes, while `2+1` cannot. Mirror copy counts and journal/tree write policies are also configured independently rather than derived from one system protection contract. See [chunkdb placement](../design/chunkdb/design-crowdb-chunkdb.md) and [chunk IO](../design/chunkio/design-crowdb-chunkio.md). + +Operators need to choose a node failure budget for a deployment without accidentally admitting an EC shape or mirror layout that loses committed data within that budget. When nodes fail, new placement must use the remaining budget and record any loss of the full-cluster protection target for repair after recovery. + +#### Solution + +The system property `max_node_failures` is the number of unavailable nodes the configured deployment promises to tolerate from its complete topology. It is a protection target, not an automatic instruction to reduce copies each time a node fails. The remaining budget is the target minus the nodes already unavailable. A production profile must have enough voting KV replicas to retain quorum at that target and enough distinct storage nodes to place its selected layouts. The explicit test-single-node profile has a zero budget. Startup and allocation reject mismatched service policy, impossible budgets, and unsafe layouts; failure never silently switches deployment mode. + +For a mirror strip, the full protection target requires at least `max_node_failures + 1` copies on distinct nodes. Continue to use the full copy count after a failure when placement permits it. For an EC strip with `k` data and `m` parity fragments, sort per-node fragment counts descending; the sum of the largest `max_node_failures` counts must be at most `m` in a healthy topology. Apply the corresponding remaining-budget check to new allocations after failures. Keep fragments spread across available nodes even when no further node-failure budget remains.

Select mirror copy counts from the deployment contract, while retaining explicit per-strip policy only when it meets or exceeds the target. +3. During an outage within the configured budget, try full protection first. If it cannot fit, permit a layout that meets the remaining budget, persist a degraded-placement marker, and create a durable placement task. Reject allocation if even the remaining-budget layout or KV quorum is unavailable. Never claim full protection for a degraded strip. +4. After capacity returns, use fenced placement tasks to move or rebuild fragments until the original target holds. Reads and writes follow each strip's persisted geometry throughout migration; a restart resumes unfinished tasks without accepting stale placement. + +#### Dependencies + +- R192 supplies the two concrete deployment profiles, strip dispatch, and placement-repair baseline.

The first divergence inside DiskDB's asynchronous relocation worker remains unconfirmed; keep the acceptance result separate from the one-node outage work. - [ ] **Final cleanup**: remove R192, its backlog entry, and this plan in the final cleanup commit after acceptance passes. diff --git a/lib/crowdb-chunk-client/src/chunk/mirror_chunk_writer.rs b/lib/crowdb-chunk-client/src/chunk/mirror_chunk_writer.rs index e7cf8a5d..b6cf8676 100644 --- a/lib/crowdb-chunk-client/src/chunk/mirror_chunk_writer.rs +++ b/lib/crowdb-chunk-client/src/chunk/mirror_chunk_writer.rs @@ -34,7 +34,7 @@ pub struct MirrorChunkWriter { } impl MirrorChunkWriter { - /// Allocates one three-copy WAL chunk with a fixed logical capacity. + /// Allocates one WAL chunk with the default mirror policy. /// /// # Errors /// @@ -53,7 +53,7 @@ impl MirrorChunkWriter { stream_name, writer_epoch, writer_lease_ms, - 3, + 2, ) .await } @@ -71,7 +71,7 @@ impl MirrorChunkWriter { writer_lease_ms: u64, copy_count: u32, ) -> Result { - if writer_epoch == 0 || writer_lease_ms == 0 || copy_count == 0 { + if writer_epoch == 0 || writer_lease_ms == 0 || !(1..=5).contains(©_count) { return Err(IoError::AllocationFailed( "stream mirror writer requires a nonzero epoch and lease".into(), ));

Rerun affected final gates after remaining acceptance. - [~] **Full-stack test stability**: `cross_domain_rebalance_hands_one_safe_move_to_target_diskdb` timed out waiting for an Accepted journal once in a concurrent 36-test run and once alone, then passed six isolated runs and a full concurrent rerun. The first divergence inside DiskDB's asynchronous relocation worker remains unconfirmed; keep the acceptance result separate from the one-node outage work. - [ ] **Final cleanup**: remove R192, its backlog entry, and this plan in the final cleanup commit after acceptance passes.

Move Iceberg foreground client wiring and file-storage policy selection into `crowdb-access-iceberg`. Keep S3 metadata in its S3 library and table/catalog metadata in its Iceberg library. Preserve the separate Iceberg GC client pool when GC is enabled. -4. Give S3 and Iceberg their own small-write and large-write EC, memory, and prefetch settings. Do not require the two EC schemes to match. Large-write EC remains a policy of each write/strip; this requirement does not force all future strips in a chunk to use one EC scheme.

Healthy `2+1`, `4+2`, and `8+4` EC layouts place at most their parity count of fragments on any one node. After one node fails, the remaining node-failure budget is zero: new mirror strips still allocate two copies across the survivors, while new EC strips may place their fragments across those two nodes, mark the placement degraded, and create a durable repair task. A second node failure is outside this profile's guarantee; neither placement nor deployment mode silently falls back to a one-copy mirror. - -Single-node is an explicit test-only mode. It has one KV server and one voting copy per KV group. Every new chunk strip has 1 MiB logical data capacity and one mirror copy; EC, multiple mirror copies, and mirror-to-EC conversion are disabled.

This mode provides no data protection and cannot be entered automatically because of missing nodes, failed placement, or quorum loss. -Its `max_node_failures` property is `0`. - -Existing colocated EC integration fixtures use a separate explicit -`test_unsafe_placement` mode, accepted only by debug builds.

Make the deployment protection mode and its fixed `max_node_failures` value explicit in startup configuration. Validate the KV replica topology and chunk placement policy against them before serving writes. Reject a production configuration with fewer than three voting nodes, a mismatched failure budget, or a single-copy mirror, and reject test-only single-node configuration that requests multiple copies or EC. -2. Treat a chunk as a sequence of strips, each with its own logical data capacity and protection layout. The chunk write path advances through strips and delegates block alignment, cross-block writes, mirror duplication or EC encoding, durability, and repair to the selected strip writer. A mirror strip writer must handle the single-copy test layout and protected mirrored layouts. The read path dispatches to the matching strip reader, whose error recovery is layout-specific. -3. Keep foreground write policy in each access library and physical strip I/O in chunk-client. S3 and Iceberg may choose separate policies; neither decides placement or performs EC encoding itself. Existing small-write admission remains independent of the large-write path while sharing strip-level semantics where appropriate. -4. In a healthy three-node cluster, place two-copy mirror strips and EC layouts so loss of any one node leaves enough information to read committed data. After one node fails, retain the original protected-cluster identity and quorum. First replace a failed mirror segment on the unused surviving node; if replacement fails, rotate the chunk and retry the uncommitted write once, returning an error if rotation or retry fails. Keep two-copy mirror placement for new strips. Permit new EC writes across the two survivors with a persisted degraded-placement marker and durable repair task; never silently allocate a one-copy strip. Recover the full EC placement when the third node returns. -5. Let mirror strip I/O use its configured copy count from one through five.

A focused production stream test starts three live fault-injected DiskIO processes, verifies a failed write rotates once, returns within 15 seconds, and leaves the journal tail unchanged.

First divergent server error in `crowdb-chunk-kv-server-20260930-020901.967-326637.log`: `chunk KV journal stream append failed error=stream metadata or data is corrupt: stream chunk mirror count differs from configuration`. -- Attempts: initial outage run showed a 503; S3 application logging identified `PutOutcome::Timeout`; S3 library logging located the Chunk-KV operation deadline; `MirrorChunkWriter` geometry fix exposed a stopped ChunkDB range owner; pinning the protected fixture's ChunkDB instance to surviving node 1 exposed the current journal geometry rejection. Each run kept the same old-read/new-write outage acceptance. -- Diagnosis at the time: the old three-copy mirror policy used every node, so a failed copy had no unused survivor for replacement. Rotation allocated two copies, but `lib/crowdb-chunk-stream/src/production_chunk.rs` compared their count with the configured three and classified the stream as corrupt.

Exact-object FileIO already supports the small TPC-H and TPC-DS loader flow; listing is not a prerequisite for that flow. + +#### Problem + +The native Iceberg file endpoint accepts signed operations on exact immutable objects, but rejects `ListObjectsV2`. [PyIceberg's PyArrow S3 FileIO](https://py.iceberg.apache.org/reference/pyiceberg/io/pyarrow/) calls PyArrow `get_file_info` for `exists` and length, which can issue `ListObjectsV2` even when the caller has an exact object path. In a local SF 0.01 loader run, that call failed before upload with `InvalidRequest`. A CrowDB-specific FileIO can use exact-object HEAD-backed reads and complete this load, but clients that intentionally list prefixes still lack an answer. [Iceberg's FileIO guide](https://iceberg.apache.org/docs/latest/fileio/) names read, write, and seek as essential file operations and tracks data paths in table metadata; it does not make S3 prefix listing an essential FileIO operation. This requirement must establish which clients actually need S3-style listing before extending the native file endpoint. + +The current S3-shaped file location uses an encoded catalog ID in the URI authority field and a `t//` key prefix. This is a routing convention, not a declared Iceberg bucket. The native service has no general S3 bucket authority or file DELETE, and the general S3 service has separate authority. See [native Iceberg design](../design/access-server/iceberge/design-crowdb-iceberg.md) sections 3 and 6. + +#### Solution + +Research and record the exact API call sequences of PyIceberg, Arrow, DuckDB, and any engine accepted under R189. Distinguish incidental listing used for exact-object existence from intentional prefix discovery. Check the Iceberg FileIO and REST Catalog contracts separately; compatibility with an S3-shaped URI alone does not make S3 bucket/list semantics part of Iceberg. + +Choose an address model only after that research. The S3 request's bucket field could represent a catalog, a table, or an opaque native routing scope. Preserve catalog/table IDs as first-class Iceberg authorities and avoid creating general S3 bucket records or granting cross-table discovery by default. Document what each choice means for existing table locations, catalog isolation, credentials, pagination, and future multiple-catalog deployments. There is no historical-data compatibility requirement, but an address change must still be atomic for active tables and clients. + +If intentional listing is needed, implement only the chosen native listing contract: + +1. Extend `app/crowdb-access-server/src/iceberg/file_request.rs` and the native route selection to parse and validate `ListObjectsV2` parameters, including prefix, delimiter, continuation token, encoding, and page limit.

Add authorized, bounded prefix scans over published file records in `lib/crowdb-access-iceberg/src/file/repository.rs` and its catalog storage. Return only files visible to the caller's table scope; exclude drafts, uncommitted uploads, losing CAS candidates, and retired files according to a documented visibility rule. +3. Extend `lib/crowdb-access-iceberg/src/file/credentials.rs` and credential vending only if a distinct list permission is needed. Bind it to the chosen routing scope and table authorization, with no privilege inherited from the general S3 service. +4. Make pagination stable under concurrent publication and deletion. Bind continuation tokens to the caller, scope, prefix, delimiter, and listing generation or equivalent consistent cursor. Bound scan work and response size; reject malformed, expired, or cross-scope tokens. +5. Add protocol and official-client tests for clients shown by the research to require listing.

Until this requirement is implemented, use an exact-object FileIO for clients that only need Iceberg table files. +- The native file, catalog, and credential contracts in the [Iceberg design](../design/access-server/iceberge/design-crowdb-iceberg.md) define the present authority boundary. General S3 listing is not a fallback for native Iceberg files. +- If research finds no client that needs intentional prefix listing, close this requirement with the client evidence and retain only exact-object FileIO adapters. + +#### Acceptance + +- Given the chosen supported clients and a current container, trace an exact-file open and an intentional prefix query; record which client issues each request and which Iceberg or S3 interface it relies on. Assert the decision does not infer an Iceberg listing requirement from a PyArrow existence probe alone. Integration test. +- Given each proposed address model, resolve two catalogs and two tables with different principals; assert routing and authorization cannot expose another table's names or files. Select and document one model before implementing the endpoint. Integration test. +- Given an authorized table with committed, staged, abandoned, and retired file records, request a native listing prefix; assert only the chosen visible set appears, while an unauthorized principal sees none. Integration test. +- Given more matching files than one page, request successive pages with prefix and delimiter; assert bounded pages have no duplicate or omitted eligible keys and tokens cannot be replayed under another principal or scope. Integration test. +- Given concurrent file publication or reclamation during pagination, continue listing; assert the documented snapshot or cursor rule, with bounded work and no cross-table leakage. Integration test. +- Given malformed parameters, foreign catalog/table routes, and attempts to use general S3 credentials, issue a native list request; assert fail-closed responses before scanning. E2E test. +- Given exact-object PyIceberg reads and writes, run the existing native FileIO tests after any routing change; assert they still work without `ListObjectsV2`.

Is the behavior required by the Iceberg FileIO or REST Catalog specification, or by a particular S3 client implementation? +- Should the S3 bucket field map to a catalog, a table, or an opaque native routing scope? A catalog keeps existing locations compact but makes per-table isolation rely on key prefixes; a table makes isolation explicit but affects location and credential vending; an opaque scope allows routing evolution but is less readable to clients. +- Should listing include only files reachable from current table snapshots, all retained snapshots, or every published immutable file awaiting reclamation?

It covers file publication, not table +snapshot publication. + +Depends on: [Native Iceberg Storage](design-crowdb-iceberg.md) and +[Chunk I/O](../../chunkio/design-crowdb-chunkio.md). + +## Table of contents + +1.

[Interpretation and next measurements](#4-interpretation-and-next-measurements) + +## 1. Client and server flow + +The TPC loader writes one local Parquet part at a time through `CrowdbFileIO`. +It copies bounded input buffers into the PyArrow output stream while computing +a local SHA-256 digest. It does not read the uploaded object back. Closing the +stream waits for the FileIO transfer to finish. Only after all files for a +table are uploaded does the loader import them and commit the table once. + +PyArrow currently uses multipart FileIO even for the measured 64-KiB object: + +1. FileIO checks whether the exact target exists, then starts a multipart + session. Neither step publishes a table snapshot. +2. Each `UploadPart` authenticates and validates its body, prepares a chunk + writer, streams bytes to Chunk I/O, finishes the writer, and persists the + part's locations and session progress. The write path verifies the supplied + body integrity information before accepting it. +3. `CompleteMultipart` freezes the selected parts and assembles their chunk + locations into one file record. Native stream parts are composed logically; + completion does not copy the object payload. The file mapping is then + published. Recovery can resume an interrupted completion. +4. A later Iceberg table commit publishes metadata that references this file. + Uploaded files remain outside the table snapshot until that commit. + +Writer selection uses the decoded length of each HTTP request, when available. +Payloads below the small-object threshold can use the small-object writer for +one frame or the shared-object writer for a longer request. Other requests use +the large writer. The total logical file size alone does not select the writer. +The large writer drives chunk strips and seals its locations on completion. + +## 2. Large file measurement + +On 2026-10-01, a local single-node container received a 100-MiB generated +object through the same `CrowdbFileIO` output API as the loader. The object was +not registered in an Iceberg table. Two runs took 6.23 s and 5.90 s. The second +run's stage and server-counter deltas were: + +| Measurement | Result | +| ------------------------------------- | ----------: | +| Create output stream, including probe | 0.322 s | +| Thirteen 8-MiB client writes | 0.075 s | +| Close and finish multipart transfer | 5.507 s | +| End-to-end elapsed time | 5.904 s | +| Effective logical throughput | 16.9 MiB/s | +| Successful FileIO HTTP requests | 12 | +| Catalog GET operations | 144 | +| Catalog compare-exchange operations | 16 | +| Small-write completions | 0 | + +The 12 successful requests are consistent with creating a session, uploading +parts, and completing it. The existence probe returns not found and is not in +the success count. The summed server dispatch time was 31.61 s across requests; +multipart part requests overlap, so this sum is not wall-clock latency. + +The client writes returned in 75 ms because PyArrow buffers or schedules the +transfers. The 5.5-s `close()` wait is the dominant observed client stage. +The zero small-write delta rules out the small-object queue as the path for +this 100-MiB sample. Catalog GET and CAS counts show metadata work remains +per multipart session and part, rather than a single final table update. +These counters do not yet isolate network transfer, chunk allocation, DiskIO, +or sealing within the 5.5-s wait. + +## 3. Small file measurement + +The same container and API were used for three generated objects. Each used +three successful FileIO requests, 45 catalog GETs, and seven catalog CAS +operations, even though the payload sizes differed. + +| Object size | Open | Client write | Close | Total | Small-write completions | +| ----------- | ------: | -----------: | ------: | ------: | ----------------------: | +| 64 KiB | 0.345 s | <0.001 s | 1.242 s | 1.587 s | 1 | +| 1 MiB | 0.328 s | <0.001 s | 1.213 s | 1.541 s | 0 | +| 5 MiB | 0.344 s | 0.001 s | 1.498 s | 1.844 s | 0 | + +The 64-KiB transfer completed through the small-write queue. The 1-MiB and +5-MiB requests did not increment that counter; the available metrics do not +separate shared-object from large-writer completions. Fixed FileIO session, +part, and completion work is material for a small object. The table-level +commit is not included in these timings. + +## 4. Interpretation and next measurements + +The loader's local copy and checksum loop is not the measured bottleneck for +these generated objects. The large-file wait is inside remote multipart +completion and its concurrent part uploads. A 100-MiB transfer still takes +about six seconds on this single-node setup, which is too slow to dismiss as +file size alone. The current metrics do not identify a specific erroneous +server operation, so changing writer policy or removing metadata checks would +be premature. + +The next diagnostic comparison is a direct 100-MiB PUT against multipart +UploadPart requests with equal payload and durability settings. Per-request +timing should then split transfer, chunk preparation, DiskIO completion, part +state publication, and final file publication. For small files, measure the +same stages separately from the exact-object probe and multipart session +setup. Catalog GET and CAS counts should be traced to operation names before +removing any recovery or fencing reads. diff --git a/doc/doc_index.md b/doc/doc_index.md index f57984c7..48dea52e 100644 --- a/doc/doc_index.md +++ b/doc/doc_index.md @@ -32,16 +32,17 @@ listed document or section needed by the task. ## Working & Flow-Analysis Docs Temporary plans live under `doc/working/`; flow analyses live under -`doc/design/{kv,chunkio,rpc}/`. - -| Doc | When to read | -| ------------------------------------------------------ | ---------------------------------------------- | -| `doc/design/kv/kv-read-flow-analysis.md` | KV point-read flow and benchmarks. | -| `doc/design/kv/kv-scan-flow-analysis.md` | KV scan flow and benchmarks. | -| `doc/design/kv/kv-write-flow-analysis.md` | KV write flow and optimization evidence. | -| `doc/design/chunkio/chunkio-write-flow-analysis.md` | Chunk I/O large-write flow and benchmarks. | -| `doc/design/chunkio/chunkio-small-io-flow-analysis.md` | Chunk I/O small-I/O flow and benchmarks. | -| `doc/design/rpc/rpc-flow-analysis.md` | RPC flow, benchmarks, and performance history. | +`doc/design/{access-server,kv,chunkio,rpc}/`. + +| Doc | When to read | +| ----------------------------------------------------------------------- | ------------------------------------------------------- | +| `doc/design/kv/kv-read-flow-analysis.md` | KV point-read flow and benchmarks. | +| `doc/design/kv/kv-scan-flow-analysis.md` | KV scan flow and benchmarks. | +| `doc/design/kv/kv-write-flow-analysis.md` | KV write flow and optimization evidence. | +| `doc/design/chunkio/chunkio-write-flow-analysis.md` | Chunk I/O large-write flow and benchmarks. | +| `doc/design/chunkio/chunkio-small-io-flow-analysis.md` | Chunk I/O small-I/O flow and benchmarks. | +| `doc/design/access-server/iceberge/design-crowdb-iceberg-upload-flow.md` | Iceberg FileIO upload path and container measurements. | +| `doc/design/rpc/rpc-flow-analysis.md` | RPC flow, benchmarks, and performance history. | ## Dev Environment (`doc/dev/`) diff --git a/lib/crowdb-chunk-stream/src/stream.rs b/lib/crowdb-chunk-stream/src/stream.rs index 1f75801f..b7340423 100644 --- a/lib/crowdb-chunk-stream/src/stream.rs +++ b/lib/crowdb-chunk-stream/src/stream.rs @@ -1459,10 +1459,11 @@ async fn resolve_cursor_advance( "committed cursor has an unexpected checksum".into(), )); } - Ok(_) => { - return Err(StreamError::Corruption( - "durable cursor is outside the append bounds".into(), - )); + Ok(durable) => { + return Err(StreamError::Corruption(format!( + "durable cursor is outside the append bounds: chunk={chunk_id:?} epoch={} expected={expected_cursor} new={new_cursor} durable={}", + state.writer_epoch, durable.offset + ))); } Err(StreamError::StaleWriter) => return Err(StreamError::StaleWriter), Err(error) => { diff --git a/lib/crowdb-kv-client/src/client/core.rs b/lib/crowdb-kv-client/src/client/core.rs index 67efabd8..0831b25a 100644 --- a/lib/crowdb-kv-client/src/client/core.rs +++ b/lib/crowdb-kv-client/src/client/core.rs @@ -148,16 +148,13 @@ impl CrowdbKvClient { } fn build(config: ClientConfig, transport: Option>) -> Self { - // Log client creation so accidental instance proliferation - // (each with its own topology cache + connection pool) is - // visible in logs.

The chunk writer keeps +exclusive mutable ownership of its state; do not introduce a hot-path lock, +per-frame virtual dispatch, or a kernel wake for every buffer.

Partial frames and chunk rotation remain valid + without an object-sized copy. +- **I3 — Durable publication.** Accepted buffers stay owned until writer + and digest views finish.

The chunk IO regression script exercises +the writer below HTTP decoding, request integrity, and protocol publication. +Consequently, a change can improve chunk IO while slowing S3 or Iceberg PUT, +multipart part upload, or metadata publication without a comparable measurement. +See the [access server design](../design/access-server/design-crowdb-access-server.md), +[Iceberg upload-flow analysis](../design/access-server/iceberge/design-crowdb-iceberg-upload-flow.md), +and [shared upload-flow requirement](R195-access-shared-large-upload-flow.md). + +#### Solution + +Extend `crowdb-cli bench` with one real HTTP upload workload driver that uses +the same measurement, payload generation, concurrency, and result schema for +S3 and Iceberg. Keep the existing memory-backed `bench s3` contract unchanged. +Protocol adapters perform authentication, target setup, direct PUT or multipart +requests, response validation, and cleanup. A timed sample starts immediately +before request submission and ends only when the server acknowledges the +durable write and the protocol's corresponding object, file, or part record is +published. Multipart completion is a separate timed phase; an Iceberg table +snapshot commit is not included in FileIO upload latency and is reported +separately if exercised. + +The workload reuses a prepared, deterministic 1-MiB payload block for large +objects and computes expected integrity values before timing. Streaming does +not allocate or copy an object-sized client buffer, hash the full object in the +timed loop, or read the object back after every successful upload. A bounded +sample outside the timed interval verifies stored bytes and range boundaries. +The CLI reports client preparation and transfer timings separately so client +work is not mistaken for server time. + +The regression scripts own a reproducible local single-node storage and +access-server deployment by default, using the project's existing deployment +and configuration facilities. They retain service logs, metrics snapshots, +machine-readable per-operation samples, and a summary under one run directory. +An explicit remote-endpoint mode uses the same workload against a supplied +server without claiming local process or storage metrics. The scripts compare +only like-for-like topology and configuration profiles. + +The following invariants define the benchmark: + +- **I1 — Real protocol path.** Every timed S3 and Iceberg sample crosses the + HTTP access server, request integrity checks, chunk writer, and the relevant + protocol publication. The report distinguishes direct PUT, multipart part, + multipart completion, and optional table commit. +- **I2 — Controlled input.** Size, concurrency, operation count or duration, + warmup, payload seed, request integrity mode, and deployment profile are + recorded. Client payload memory is bounded independently of object size. + Preparation, namespace/table/session setup, final verification, and cleanup + are outside the timed upload samples. +- **I3 — Honest completion.** The driver records admitted, completed, failed, + and incomplete operations, drains admitted work before exiting, validates + success responses and ETags/digests, and exits nonzero for any failed, + missing, or unverified operation. A timeout or metrics-collection failure + remains visible in the retained result. +- **I4 — Comparable measurements.** Both protocols emit the same JSON and TSV + fields for object size, concurrency, request count, logical bytes, elapsed + time, throughput, average, p50, p95, p99 when sample counts support them, + and error classes. Percentiles with too few samples are absent, not inferred. + The report includes client CPU/RSS and, for local runs, access-server + CPU/RSS and before/after server metric deltas. The shared write-flow stage + counters from R195 are included when available, with concurrent stage + durations reported separately from wall-clock latency. +- **I5 — Regression decision.** The default sentinel gates correctness, + completion, timeout, artifact presence, and required metric availability. + Throughput and latency comparisons use an explicitly selected baseline for + the same profile and a documented tolerance; they do not use one fixed + hardware-dependent number. The result states whether a case was measured, + comparable, regressed, or invalid, and names the failing condition. + +Work items: + +1. Add a real HTTP upload verb and shared result model under + `app/crowdb-cli/src/commands/bench/` and its workload implementation under + `lib/crowdb-console-shared/src/ops/`. The CLI accepts protocol, endpoint, + direct or multipart mode, workload bounds, output path, and credentials via + existing environment/config conventions. Reuse the same input producer and + percentile/accounting logic for both protocol adapters. Do not route this + workload through the memory-backed `bench s3` engine. +2. Implement S3 and Iceberg upload adapters. For S3, cover direct PUT and + UploadPart plus CompleteMultipart. For Iceberg, cover native FileIO direct + PUT and multipart part plus completion against an authorized table/file + scope. Preserve each protocol's signing, integrity, ETag, and publication + rules; never count a successful part as a published final object. Report + client-side signing or hashing work separately if the selected integrity + mode requires it. +3. Add `tools/benchmark/` regression scripts modeled on + `bench-chunkio-write-regression.sh`. Use a named local deployment profile, + build required binaries through `pixi run`, start and clean up the stack, + execute isolated S3 and Iceberg cases, retain full output and service + metrics, and print a compact per-case summary. Provide bounded timeouts + and a case filter for focused runs. Support explicit remote endpoints + without trying to destroy a remote deployment. +4. Include a small-path case below the configured threshold, a boundary + case, direct 100-MiB PUT, and multipart 100-MiB upload for each protocol. + Run at least one single-client and one concurrent-client case. Record the + exact threshold, part size, mirror/EC policy, durability setting, and + software revision with each run so changed profiles are not silently + compared. Keep setup and verification outside timed samples. +5. Save a baseline artifact and comparison contract for each supported local + profile. Accept an optional reference result and tolerance in the runner; + reject comparisons across incompatible profiles. Preserve raw samples and + metrics for diagnosis even when a case fails. + +#### Dependencies + +- The existing local deployment facilities, access-server S3 and Iceberg + HTTP routes, protocol credentials, and chunk IO benchmark artifact + conventions are the baseline.

The 13-part profile (four concurrent uploads) completed in 613 ms: 48 ms session creation, 404 ms part phase, 162 ms completion. Across 13 parts, server metrics summed 905 ms writer feed, 198 ms part publication, 98 ms digest enqueue, and 83 ms body polls; these sums overlap. One earlier profile run returned HTTP 200 for completion but got a 404 on subsequent range read, while two later runs passed; determine whether the completion body carried an embedded error. Baseline does not gate the flow implementation. +- [x] **Measure strip readiness and write completion**: The focused single-node, one-mirror, null-DiskIO 100-MiB PUT passed in 2.056 s after adding the counters. Writer feed occupied 1.920 s; waiting for the next strip occupied 0.795 s across 52 waits, while 101 successful `strip.push` calls occupied 0.309 s total (6.35 ms maximum). These stages overlap with receive and digest. Default `prefetch_strips_per_chunk` is 1; inspect prefetch runway before changing write concurrency. +- [x] **Batch known-size large-write strip prefetch**: Keep the initial chunk allocation and ordinary prefetch depth at one strip. For a known-size large write, cap each append batch by the object's remaining framed bytes, the chunk's strip capacity, and configurable `large_prefetch_max_strips_per_batch` (default 32). Start the next append after half of the prior batch has been consumed. The same 100-MiB PUT passed in 0.836 s and 1.035 s in two local runs; strip preparation wait fell to 2 waits/17 ms and 1 wait/43 ms respectively, while `strip.push` success time stayed near 255–259 ms. Treat these as samples, not a stable throughput distribution. +- [x] **Measure the four-write coroutine flow**: A focused 100-MiB PUT on the single-node null-DiskIO fixture passed in 335.9 ms after forwarding capacity waits through `PreparedLargeWrite`.

The 558.0 ms sum of 101 strip-write durations and 234.3 ms digest CPU time overlap other stages and are not additive wall time.

Writer feed occupied 1.920 s; waiting for the next strip occupied 0.795 s across 52 waits, while 101 successful `strip.push` calls occupied 0.309 s total (6.35 ms maximum).

Start the next append after half of the prior batch has been consumed. The same 100-MiB PUT passed in 0.836 s and 1.035 s in two local runs; strip preparation wait fell to 2 waits/17 ms and 1 wait/43 ms respectively, while `strip.push` success time stayed near 255–259 ms. Treat these as samples, not a stable throughput distribution. - [x] **Measure the four-write coroutine flow**: A focused 100-MiB PUT on the single-node null-DiskIO fixture passed in 335.9 ms after forwarding capacity waits through `PreparedLargeWrite`.

The 558.0 ms sum of 101 strip-write durations and 234.3 ms digest CPU time overlap other stages and are not additive wall time.

The staged access-server binary resolves both `libcrypto.so.3` and `libssl.so.3` from the staged library directory, sourced from the pixi environment. Still run MD5 and SHA-256 upload smoke in the built image. Files: `container/single-node-container/collect-libs.sh`, relevant container smoke test. +- [~] **Check packaged OpenSSL**: The current working tree built `crowdb-iceberg-single-node:dev` successfully. `image-smoke.sh` passed, including packaged `libcrypto.so.3` linkage and runtime entrypoint checks. The 100-MiB direct small-cluster test exercises valid MD5, invalid MD5, and signed SHA-256 requests, but image-level digest upload smoke remains.
