During February 2026, Greg Williams focused on optimizing moderation event queries in the bluesky-social/atproto repository by introducing a creator-based database index. He designed and implemented the moderation_event.createdBy index using TypeScript and database management skills, refining index columns to better align with runtime query patterns and removing redundancies for improved maintainability. Greg also developed comprehensive tests to validate querying moderation events by creator, ensuring robust coverage and preventing regressions. Although no major bugs were fixed during this period, his work established a scalable indexing strategy that improved query latency and laid the groundwork for future enhancements in moderation event handling.
