June 2025 monthly work summary focusing on documenting correctness and readability improvements for the Doris website SQL docs. The main emphasis was on ensuring the SQL documentation is accurate, easy to read, and aligned with actual behavior, reducing user confusion and support queries.

2025-03 monthly summary for apache/doris: Focused on stabilizing and expanding test coverage for cold/hot data separation. Key achievements include stabilizing regression tests for cold_heat_separation_p2 by refactoring tablet data access to named properties and updating SQL query result mappings to handle arrays, addressing flaky failures; added a dedicated HDFS regression test to verify proper compaction and data movement per storage policies, improving coverage. These changes reduce test flakiness, increase reliability, and lower production risk. The work demonstrates strong regression testing, data lifecycle awareness, and test automation across storage tiers.

In February 2025, delivered targeted documentation improvements, startup log guidance, and robust cold data cleanup fixes across Doris repositories, strengthening product reliability and onboarding experience. Key work included documenting and fixing navigability issues, clarifying startup messages, and ensuring storage hygiene after cold data operations.
