📝 Walkthrough

Walkthrough

Adds configurable Elasticsearch integration with asynchronous Doctrine synchronization, revision-ordered indexing, subscriber history and bounce search readers, index initialization and reindex commands, CI support, and operational documentation.

Changes

Elasticsearch search infrastructure

Layer / File(s) Summary
Search contracts and configuration
composer.json, .env*, config/parameters.yml, config/services/*, src/Domain/Search/Model/*, src/Domain/Search/Registry/*, src/Domain/Search/Exception/*
Defines search contracts, registries, runtime parameters, service wiring, and the Elasticsearch dependency.
Elasticsearch client and index management
src/Domain/Search/Client/*, src/Domain/Search/Service/*, tests/Unit/Domain/Search/Service/*
Adds revision-aware indexing and deletion, prefixed physical index names, index provisioning, and backend exception wrapping.
Asynchronous search synchronization
src/Core/Doctrine/*, src/Domain/Search/Message/*, src/Domain/Search/MessageHandler/*, config/packages/messenger.yaml, .github/workflows/ci.yml, tests/Unit/Core/Doctrine/*, tests/Unit/Domain/Search/*
Buffers Doctrine changes until postFlush, dispatches revisioned messages, processes index and delete operations, and verifies stale-operation handling.
Subscriber history search integration
src/Domain/Subscription/*, src/Domain/Common/Model/PaginatedResult.php, config/services/repositories.yml, tests/Unit/Domain/Subscription/*
Adds the subscriber history search model, mapping, reindex provider, Elasticsearch reader, cursor pagination, and interface-based manager wiring.
User message bounce search integration
src/Domain/Messaging/*, src/Domain/Analytics/*, config/services/repositories.yml, tests/Unit/Domain/Messaging/*, tests/Unit/Domain/Analytics/*
Adds bounce indexing, Elasticsearch and database reader implementations, read models, filtering, reindex support, persistence, and interface-based analytics wiring.
Search operations and documentation
src/Domain/Search/Command/*, config/services/commands.yml, .env.test, .env.test.local.dist, README.md, docs/ElasticsearchSearch.md
Adds index initialization and reindex commands, test settings, command examples, and Elasticsearch documentation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 49119

The bounce reader can fail to load, repeat database pages, or omit large histories. Concurrent and retried indexing can also restore stale search data, so these issues should be fixed before merge.

50-50: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Prevent stale search messages from restoring deleted documents.

With the default Doctrine transport, a failed index message may be retried after a later delete message. IndexDocumentMessage has no document version, and IndexDocumentMessageHandler applies every operation without a stale-message check. Add monotonic document versions and reject stale Elasticsearch operations. Add a regression test for failed index → successful delete → index retry.

max_connect_duration option with connect_timeout so the configured connection
timeout is applied by the default Guzzle transport while preserving the existing
connectTimeout value.

In `@src/Domain/Subscription/Repository/SubscriberHistoryElasticsearchReader.php`:
- Line 75: Update the result construction in the Elasticsearch reader to set
lastId from the final hit’s idSort value rather than filter->getLastId(). Add a
two-page test that passes PaginatedResult::getLastId() into the next filter and
verifies pagination advances without repeating results.

Elasticsearch 8 external_gte version_type equal version accepted lower version conflict official documentation

💡 Result:

When using the external_gte version type in Elasticsearch, a document is indexed only if the provided version is equal to or higher than the version of the currently stored document [1][2]. If the provided version is strictly lower than the version of the stored document, the operation will fail with a version conflict [3][2]. The official documentation explicitly notes that the external_gte version type is intended for special use cases and should be used with care [1][4]. Because it allows indexing when versions are equal, it can result in data loss if used incorrectly—specifically in scenarios where stale data might accidentally overwrite newer data if the external versioning logic is not carefully managed [5][6]. Unlike standard external versioning (which requires the incoming version to be strictly higher), external_gte permits the same version to be written, which is primarily useful for replaying documents or ensuring that retried operations do not fail simply because they have been processed before [3]. Key technical details: - Version comparison: Incoming version > stored version (Accepted), Incoming version == stored version (Accepted with external_gte), Incoming version < stored version (Rejected with conflict) [1][3][2]. - Use cases: Commonly used during reindexing or data recovery processes where you may need to replay operations without failing on already-indexed documents [3]. - Update API: The use of external or external_gte version types is generally disallowed in the Update API to prevent unexpected data loss and integrity issues [7][8].

Citations:


Use a shared monotonic revision source.

SearchIndexDoctrineListener::nextRevision() uses wall-clock time. Equal revisions are accepted by ElasticsearchClientAdapter because it sends version_type: external_gte. An equal-version stale retry can therefore overwrite a newer document. If the clock moves backward, an earlier delayed message can also receive a higher revision and overwrite a later update.

Use a shared monotonic revision source tied to the database write, or use a per-document version. Test equal revisions delivered out of order and backward clock movement.

Elasticsearch 8 index API automatic index creation delete API missing index external_gte version_type automatic create

💡 Result:

In Elasticsearch 8, automatic index creation, delete API behavior, and versioning types operate as follows: Automatic Index Creation Automatic index creation is controlled by the cluster setting action.auto_create_index [1][2]. When set to true (the default), Elasticsearch automatically creates an index if it does not exist when a document is indexed [1][3][2]. This setting can be customized to allow or block specific index patterns using a comma-separated list of patterns (e.g., +allow*, -block*) [2][4]. Note that this setting specifically governs indices and does not affect the automatic creation of data streams, which are handled via index templates [3][2]. Delete API The Delete Index API is used to remove one or more indices, which also deletes their documents, shards, and metadata [5][6]. - By default, the API does not support wildcards (*) or _all to prevent accidental mass deletion [5][6]. This protection can be disabled by setting the cluster configuration action.destructive_requires_name to false [5][6]. - If an index does not exist, the API will return an error by default [6]. - The ignore_unavailable query parameter can be set to true to ignore requests that target missing or closed indices [6]. Version Types (external_gte) When indexing documents, the version_type parameter allows you to control versioning, which is crucial for handling concurrency in external systems [4][7]. - external: The document is indexed only if the provided version is strictly greater than the currently stored version [4][7]. - external_gte: The document is indexed if the provided version is greater than or equal to the currently stored version [4][7]. Using external_gte is intended for specific use cases and requires caution, as incorrect usage can potentially lead to data loss [4][7]. If a request attempts to index a document into a non-existent index using these version types, and automatic index creation is enabled, the index will be created automatically before the version check is applied [3][2]. If automatic index creation is disabled and the index does not exist, the indexing operation will fail [2].

site:elastic.co Elasticsearch document delete API index does not exist automatic index creation delete document

💡 Result:

In general, the Elasticsearch delete document API does not automatically create an index if it does not exist [1][2]. If you attempt to delete a document from an index that does not exist, the request will fail with an index_not_found_exception (404 status) [3]. While older versions of official Elasticsearch documentation occasionally contained legacy references suggesting that delete operations might trigger automatic index creation under specific versioning configurations, this is not standard behavior [1][3]. Automatic index creation is a feature primarily associated with indexing or creation APIs (such as PUT or POST), which can be controlled by the action.auto_create_index cluster setting [4][5][6]. The delete API is designed to remove existing documents and does not perform schema creation or index instantiation [1][2]. If you receive an index_not_found_exception when attempting to delete a document, it indicates that the target index has not been created or has already been deleted [3]. The system will not generate the index for you to satisfy the delete request.

Initialize search indices before consuming search messages.

If action.auto_create_index permits it, an early queued index operation can create the physical index with default settings. ElasticsearchIndexer::createOrUpdateIndex() then updates only the mapping, so the configured settings and analyzers are not applied.

Disable automatic creation for these index names and initialize indices before starting async_search.

Tie the revision to the source version, not processing time.

Line [103] assigns the revision after the entity snapshot was fetched and converted. If a live update is indexed during that interval, this reindex can submit older data with a newer revision. The revision guard can then accept the stale document and overwrite the live update.

Pass a persisted per-entity revision, or coordinate reindexing with writes, so revision ordering reflects source state.

Require a strictly newer revision.

assertGreaterThanOrEqual() accepts equal revisions. Equal Elasticsearch external_gte versions can apply conflicting delayed messages in arrival order. Use assertGreaterThan() so this test detects revision collisions across flushes.

Assert both pagination cursor queries.

The mock returns two different pages by call order only. The test still passes if getFilteredAfterId() ignores the second lastId or uses an inclusive cursor. Assert that the two requests use idSort.gt values 0 and 5.
