February 2026 Monthly Summary — Apache Doris (apache/doris) Key features delivered - Show Command Output Consistency Across Partitions, Backends, and Frontends: fixed errors, unified title names, and added missing columns for show partitions, show backends, and show frontends, improving backend/frontend information presentation. - Low WAL Disk Space Test Stabilization: stabilized low disk space regression tests by ensuring correct group commit behavior and safe async-to-sync mode transitions, reducing flakiness. Major bugs fixed - Fix partitions() error when querying internal tables without catalog condition (incompatible with show partitions command). - Fix backends UDF return rows incompatible with show backends command. - Fix frontends UDF return rows incompatible with show frontends command. - Regression test cast failures in low wal disk space tests; improved handling as per test suite updates. Overall impact and accomplishments - Increased correctness and consistency of admin/show outputs, reducing confusion and support time. - Strengthened test reliability under disk pressure, accelerating safe releases. Technologies/skills demonstrated - Backend code fixes across partitions logic and UDFs; test automation and regression testing; familiarity with asynchronous/synchronous mode transitions and group commit handling in WAL tests.
