fix(cache): close rename-cascade race and bot-task delete eviction gap#28100
Merged
Conversation
Three IT failures on the new postgres+ES+redis CI profile traced back to two cache-invalidation gaps introduced alongside #28012: 1) Classification / Tag / Glossary / GlossaryTerm / Domain renames called invalidateCacheForRenameCascade BEFORE the bulk DAO updateFqn. With invalidateCacheForTaggedEntitiesAndDescendants (search-index walk) in between, the window was ~4 s in CI traces. Any concurrent reader landing in that window loaded the still-visible pre-rename row from DB and repopulated L1+L2 cache with the old FQN, which then stuck for the entity TTL. Awaitility timeouts on ClassificationResourceIT.test_classificationRename_tagActivityFeedsPreserved and test_classificationRename_multipleTagsUpdated. Refactored invalidateCacheForRenameCascade to return the captured (id, oldFqn) pairs and added finishInvalidateCacheForRenameCascade — a post-commit pair that re-evicts the same entries by id and by old FQN, closing the race window. Updated the 6 call sites (Classification, Tag, Glossary, GlossaryTerm x2, Domain x2 for DOMAIN+DATA_PRODUCT) to capture the list pre-write and call the finish pair after all DB writes complete. 2) UserRepository.deleteSuggestionTasksForUser issued a direct DELETE FROM task_entity ... that bypassed EntityRepository.delete and its cache hook. Any task previously read by id was still pinned in the L1 Guava CACHE_WITH_ID, so the next GET returned the "deleted" task — failing TaskResourceIT.testDeletingBotCreatorCleansUpOpenSuggestionTasks. Added TaskDAO.listIdsByCreatorAndCategory, capture the ids before the bulk DELETE, then fan out EntityRepository.invalidateCacheForEntity(Entity.TASK, id, null) afterwards. List + delete are intentionally not in one transaction — over-invalidating a few extra ids on retry is cheap; missing one is the bug. mvn clean compile + spotless:check pass on openmetadata-service.

Pull request overview
This PR addresses cache invalidation gaps that caused flaky backend integration tests under the Redis cache profile: (1) rename-cascade flows could be “re-poisoned” by concurrent readers repopulating caches with pre-rename rows, and (2) bulk deletion of bot-created suggestion tasks bypassed repository delete hooks, leaving stale task entries pinned in the L1 Guava cache.
Changes:
- Refactors
EntityRepository.invalidateCacheForRenameCascadeto return the enumerated descendant(id, oldFqn)pairs and adds a symmetricfinishInvalidateCacheForRenameCascade(...)pass for post-rename re-eviction. - Updates rename flows (Classification/Tag/Glossary/GlossaryTerm/Domain + DataProduct) to capture descendants pre-update and re-invalidate after the rename-related writes.
- Fixes bot-task deletion cache eviction by listing task IDs before bulk delete and explicitly invalidating the per-task cache entries afterward.

finishInvalidateCacheForRenameCascadeis called before the subsequentclassificationChanged/parentChangedhandling (and the final response-field invalidations). SinceentitySpecificUpdateruns under@Transaction, there is still time before commit where a concurrent reader can repopulate the cache with the pre-rename row after this “finish” pass. Consider moving the finish call to the very end ofupdateNameAndParent(after the classification/parent updates and final invalidations), or invoking it again right before returning, so the post-pass is as close to commit as possible.
finishInvalidateCacheForRenameCascade(Entity.TAG, renamedTags);
}
if (classificationChanged) {
updateClassificationRelationship(original, updated);
The remaining failure on the postgres+ES+redis CI gate —
TestCaseResourceIT.testBulkFluentAPI ("Description should be bulk updated"
times out after 60s) — was a cache-poisoning race between the bulk PATCH
loop and a concurrent test running test_bulkAddAllTestCasesWithExcludeIds.
CI trace for testCase c5fa887e:
T0: bulk-add fetches all candidate test cases via Entity.getEntities(
refs, "*", ALL) — gets snapshot of c5fa887e with OLD description.
T1: testBulkFluentAPI PATCHes c5fa887e — DB committed, cache write-
through stores the NEW description (1649 bytes).
T2: bulk-add calls postUpdateMany(updatedTestCases) → writeThroughCache-
Many serializes the pre-read snapshot and overwrites Redis with the
OLD description (2158 bytes).
T3+: 60s of polling sees the poisoned cache value and never reaches
"Bulk updated".
The pre-read snapshot was load-bearing for nothing — testSuites is in the
storage-stripped field list (getFieldsStrippedFromStorageJson), so the
testCase entity JSON does not actually change here. The only DB write is
the entity_relationship CONTAINS row.
Fix in TestCaseRepository.addTestCasesToLogicalTestSuite and
addAllTestCasesToLogicalTestSuiteTxn: replace postUpdateMany with a new
postLogicalSuiteRelationshipUpdate hook that:
1. Invalidates the read-bundle cache (where testSuites is fanned out
during reads) for each affected test case — so the next GET picks
up the new relationship.
2. Fires the lifecycle "entities updated" event (event subscribers
still see the testSuites field change).
3. Updates the RDF graph.
Crucially, no writeThroughCacheMany. The base-entity JSON in Redis is
left alone, so a concurrent PATCH's write-through is not clobbered.
mvn clean compile + spotless:check pass on openmetadata-service.

… CI lane" This reverts commit 474af83.
… only) This lane has been blocking PRs on ColumnGridResourceIT.test_getColumnGrid_ withMetadataStatusIncomplete returning `[search_phase_execution_exception] all shards failed` from ES intermittently. Two attempts to stabilize it inside this PR (#28100) — @isolated on the test class and bumping ES heap from 1 GB to 2 GB — were reverted because they did NOT fix the failure: the aggregation still fails in well under 2 seconds with the class running alone, so this is not a load/parallelism issue. The ES client library is swallowing the underlying `caused_by`, so diagnosing further requires an ES-side debug log that isn't wired up yet. Rather than keep PRs red on an infra flake unrelated to the change being reviewed, disable `merge_group`/`push:main`/`pull_request_target` triggers and keep only `workflow_dispatch` so the lane can still be invoked on demand for investigation. Re-enable when the underlying ColumnGrid flake is resolved. Triggers are commented (not deleted) so re-enabling is one uncomment away. Reference: PR #28100, CI run 25936294012.

…dispatch only)" This reverts commit 47f459e.
…filter CI run 25936294012 (PR #28100) repeatedly hits [search_phase_execution_exception] all shards failed on ColumnGridResourceIT.test_getColumnGrid_withMetadataStatusIncomplete with the request fully isolated (the @isolated attempt confirmed it's not a parallelism / load issue — the aggregation still fails in <2 s with the class running alone). Root cause: `hasNonEmptyField` / `hasEmptyOrMissingField` wrapped the exists/not-exists check with an extra `term(field, "")` clause to also treat empty-string values as "missing". `columns.description` is mapped as `text` (analyzer `om_analyzer`, `similarity: boolean`, `term_vector: with_positions_offsets`); ES 9.x can reject term-on-text under that mapping inside a composite-aggregation filter wrapper and surfaces it as the generic shard-failed error with no logged caused_by, which is why earlier debugging passes found nothing useful in the container logs. The ES Java client also doesn't propagate the underlying response body, so the only signal in OM is the same generic exception. The term("") clause is also redundant: text fields analyze the empty string to zero tokens, so `exists` already returns false for the empty-description case — matching the intended "completeness" semantics. Replace both helpers with the plain `existsQuery` / `notExistsQuery` — same logical result, much simpler bool tree, and removes the cause of the shard failure. Same change applied to the OpenSearch aggregator so the two engines stay in sync. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…OMPLETE filter" This reverts commit 234f09d.
…gator flake ColumnGridResourceIT.test_getColumnGrid_withMetadataStatusIncomplete (and companion tests in the same class) reproducibly fail with [search_phase_execution_exception] all shards failed on PR #28100 across multiple search engines: - postgres+ES+redis (run 25940411467): single failure on test_getColumnGrid_withMetadataStatusIncomplete. - postgres+OpenSearch (run 25940411417): the same query crashes the OS container; after that 15 follow-up tests in the class fail with Connection refused. Same behavior occurs with and without the cache changes — confirmed by running on commits before and after the PR's cache logic. It is a pre-existing aggregator/index-mapping bug, not a cache regression. Three diagnostic attempts on this PR did not fix it: 1. @isolated on the class (run 25936294012) — test still failed alone in 1.7s, so not a parallelism/load issue. 2. ES heap 1 GB → 2 GB — no effect. 3. Drop term(field, "") clauses from the metadataStatus filter helpers (commit 234f09d, now reverted) — no effect. The ES Java client (`co.elastic.clients`) swallows the underlying `caused_by` from the response body, so root-causing requires response-body logging that is not wired up yet. Beyond the cache PR scope. Disable the class with @disabled and an explanatory breadcrumb so other PRs aren't blocked. Re-enable once the underlying aggregator issue is fixed in a follow-up.

Try a larger heap before giving up. The earlier 1 GB → 2 GB attempt (commit 474af83) wasn't enough; the failing test's symptoms differ across engines: - postgres+ES+redis: fails fast in ~1.7 s with all-shards-failed - postgres+OpenSearch: takes ~14 s before the same error, then the OS container becomes unreachable for subsequent tests The OS shape — long execution then container crash — points at heap exhaustion under the composite aggregation + top_hits load, not a purely-semantic query problem. 4 GB is conservative for a runner with ~16 GB and leaves plenty of room for the rest of the stack (postgres + redis + the OM JVM at 4 GB + maven/docker overhead). The data tmpfs is also bumped from 1 GB → 4 GB so the shard store has room for the parallel-test fixture data. Re-enable ColumnGridResourceIT (revert @disabled from e7cacc8) so this run actually exercises the test. If the heap bump fixes it the class stays enabled; if it still fails we have a tighter signal that the issue is purely query-shape and can re-disable in a follow-up.

💡 Quality: @disabled comment lacks a follow-up ticket reference
The custom instructions require that TODOs include ticket references. The comment says "Re-enable once the underlying aggregator/index-mapping issue is fixed in a follow-up" but doesn't link to a tracking issue. This makes it easy for the disabled test to be forgotten indefinitely.
Add a ticket/issue reference so the disabled test is tracked and not forgotten.:

Three IT failures on the new
Integration Tests - PostgreSQL + Elasticsearch + Redisworkflow (gate added by #28012) traced back to two cache-invalidation gaps in the cache improvements merge:Rename cascade race (ClassificationResourceIT + GlossaryRepository + TagRepository + DomainRepository):
invalidateCacheForRenameCascaderan BEFORE the bulk DAOupdateFqn. WithinvalidateCacheForTaggedEntitiesAndDescendants(search-index walk) in between, CI traces showed a ~4 s window where any concurrent reader loaded the still-visible pre-rename row from DB and repopulated L1+L2 cache with the old FQN — pinned for the entity TTL. Awaitility timeouts onClassificationResourceIT.test_classificationRename_tagActivityFeedsPreservedandtest_classificationRename_multipleTagsUpdated.Bot task delete eviction gap (TaskResourceIT):
UserRepository.deleteSuggestionTasksForUserissued a directDELETE FROM task_entity WHERE createdById=…that bypassedEntityRepository.deleteand its cache hook. Any task previously read by id was still pinned in the L1 GuavaCACHE_WITH_ID, so the next GET returned the "deleted" task — failingTaskResourceIT.testDeletingBotCreatorCleansUpOpenSuggestionTasks.Refactored
invalidateCacheForRenameCascadeto return the captured(id, oldFqn)list and added afinishInvalidateCacheForRenameCascadepost-commit pair that re-evicts the same entries; updated the 6 call sites (Classification, Tag, Glossary, GlossaryTerm ×2, Domain ×2 for DOMAIN+DATA_PRODUCT) to capture the list pre-write and finish post-write. For the bot path, addedTaskDAO.listIdsByCreatorAndCategory, capture ids before the bulk DELETE, then fan outEntityRepository.invalidateCacheForEntity(Entity.TASK, id, null)after.Type of change:
High-level design:
The pattern was that pre-commit invalidations clear stale cache entries, but anything mutating in long-running rename flows (search-index walks, ES asset updates, policy condition updates) leaves a wide race window where a concurrent reader can repopulate the L1/L2 cache from the still-visible pre-rename DB row. The new
finishInvalidateCacheForRenameCascadeis the symmetric post-commit pair — it re-evicts the descendants captured at pre-invalidate time, by id and by old FQN, closing the window. The bot-delete fix follows the same principle: any direct SQL write that bypassesEntityRepository.deletemust explicitly fan out cache invalidation, since the L1 Guava cache otherwise keeps stale rows alive past the DB drop.List-then-delete in the bot path is intentionally not transactional — over-invalidating a few extra ids on retry is cheap; missing one is the original bug.
