[congx4]

Summary

A test in the quickwit-metastore crate is consistently showing flaky behavior across multiple test runs.

Flaky Test

• metastore::postgres::metastore::tests::common_tests::test_metastore_get_identity

Behavior

This test appears as flaky in all 4 test runs with different retry counts:

• Run 1: FLAKY 2/6 [0.270s]
• Run 2: FLAKY 2/6 [0.320s]
• Run 3: FLAKY 2/6 [0.293s]
• Run 4: FLAKY 2/6 [0.359s]

Test Environment

All tests were run with make test-all and this test consistently showed flaky behavior across all runs.

Impact

This flaky test may indicate:

• Race conditions in PostgreSQL metastore operations
• Issues with test setup/teardown
• Database connection reliability problems
• Timing-sensitive assertions

Next Steps

1. Investigate the test_metastore_get_identity test implementation
2. Check for race conditions in PostgreSQL metastore operations
3. Review test database setup and cleanup procedures
4. Consider adding retry logic or improving test isolation
