test: poll for HNSW index readiness instead of fixed sleeps#9739
Merged
Conversation
TestVectorIndexRebuilding, TestVectorIndexDropPredicate, and TestVectorIndexWithoutSchema slept a fixed 5s after SetupSchema and assumed the HNSW index was ready. Rebuilding the index over pre-existing data is asynchronous, so the fixed sleep flaked on slower CI runners. Replace the sleeps with require.Eventually polling a sample similar_to query until it returns the expected result count (30s budget, 500ms interval). Also move `defer cleanup()` after the Client() error check in three tests so a cleanup from a failed Client() isn't deferred. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Rebuilding the HNSW index over pre-existing data is asynchronous, so the fixed sleep was flaky on slower CI runners — the index often wasn't ready when the assertion ran.Change
