Worked on Apache Gravitino, delivering two backend features focused on REST API performance and event-driven extensibility. Developed ETag-based caching for the Iceberg REST loadTable endpoint using Java, enabling freshness-aware responses and reducing unnecessary metadata reloads for read-heavy workloads. Ensured ETag consistency across table operations by aligning metadata and snapshot calculations, with comprehensive unit testing to validate behavior. Introduced event-driven hooks for function CRUD operations, integrating new event classes into the dispatcher chain to support observable and auditable changes without altering the public API. Emphasized robust backend development, REST API design, and event-driven programming throughout the month’s contributions.
March 2026: Delivered REST caching and event-driven enhancements for Apache Gravitino, delivering clear business value through lower read latency, reduced metadata reloads, and a more robust function-dispatch workflow.
