During February 2026, contributed two architecture-level features to the trinodb/trino repository, focusing on performance and scalability in Java-based backend development. Developed a checksum-based metadata and protocol reader for Delta tables, enabling single-shot metadata extraction and reducing planning time for large datasets by leveraging checkpoint metadata and session-property gating. Introduced the TrinoFileSystem API with a listFilesStartingFrom method, providing fast, deterministic directory listings across Azure, S3, and GCS using ASCII-based starting points. Prioritized cross-cloud compatibility and minimized I/O by reusing checkpoint data, with fallback mechanisms for legacy Delta log scanning. Work emphasized API development, cloud storage integration, and performance optimization.

Feb 1, 2026February 2026 performance-focused sprint for trinodb/trino. Delivered two architecture-level features that deliver measurable business value: (1) faster Delta planning via a checksum-based metadata/protocol reader, and (2) high-performance cross-backend directory listing via a new TrinoFileSystem API. No major bugs fixed this month; work prioritized performance, scalability, and cross-cloud compatibility. Key techniques include session-property gating, ASCII-based starting points for deterministic cross-backend listings, and reuse of checkpoint metadata to minimize I/O during planning.
