In March 2026, Akash Kumar contributed to the apache/gravitino repository by developing REST caching and event-driven enhancements for backend systems. He implemented ETag-based caching for the Iceberg REST loadTable endpoint using Java, enabling freshness-aware responses and reducing unnecessary metadata reloads for read-heavy workloads. His approach ensured ETag consistency across createTable, updateTable, and loadTable operations, optimizing performance while maintaining correctness. Akash also introduced event-driven hooks for function CRUD operations, integrating new event classes into the dispatcher chain to support observable and auditable changes. His work included comprehensive unit testing, expanding test coverage and ensuring reliability without altering user-facing APIs.
