June 2026 (apache/doris) – Monthly summary focused on delivering business value and technical achievements across frontend, BE stability, platform compatibility, and build reliability. The month delivered measurable performance improvements, safer cross-arch operation, and configurable runtime behavior, enhancing reliability and operational efficiency for production deployments.

April 2026 monthly summary for apache/doris. Focused on external catalog interoperability and GPU acceleration enhancements. Implemented ShowPartitions command validation for external catalogs and introduced a user-configurable GPU acceleration switch for FAISS, addressing build-time CUDA issues and enabling performance improvements for large datasets.

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.

Monthly performance summary for 2026-01 focused on delivering business value through reliability, security, and build stability improvements in the apache/doris repository.

June 2025: Delivered key enhancements to Doris focused on expanding data access, strengthening security, and enabling operational scalability. Key outcomes include Iceberg Views support for querying Iceberg views via the Iceberg catalog, a Kerberos authentication fix for Hudi queries to ensure secure data access, and the introduction of Broker Management REST APIs to manage broker clusters (ADD/DROP/DROP_ALL).
