April 2026: Implemented a portable SQL compatibility enhancement in apache/doris by introducing current_database() as an alias for database(). This reduces query rewrites for clients and improves cross-DB portability. The change was accompanied by regression/test updates, FE checkstyle alignment, and release notes documenting the new alias. No major defects fixed this month; the focus was on reliability, interoperability, and quality assurance.

February 2026 – StarRocks/starrocks: Documentation accuracy and clarity improvements focused on developer experience and accuracy of SQL references. Key features delivered: (1) Update SQL references to sys.fe_locks instead of information_schema.fe_locks (commit 9339bfaa7a0f6e3777ef1775357c2ef69a8f34ab); (2) Clarified ADMIN CHECK TABLET command syntax (commit 406a4bfd883b3b32b38e8c247c10f9da8bc35701). Major bugs fixed: none reported; these changes address potential user confusion and misreferences. Overall impact: higher reference quality, reduced support load, and smoother onboarding for new users. Technologies/skills demonstrated: documentation standards, SQL reference accuracy, cross-team collaboration, and sign-off discipline.
