Worked on the tursodatabase/turso repository to enhance data correctness and testing automation for transactional SQL workflows. Focused on refining upsert logic by improving row snapshot handling during DO UPDATE operations and stabilizing related test snapshots. Improved savepoint rollback reliability by ensuring proper cache management and discarding post-savepoint changes, adding regression tests to prevent future issues. Expanded the SQL snapshot testing framework to cover joins and aggregations, increasing coverage for complex query scenarios. Utilized Rust and SQL to implement these features, emphasizing robust database management, integration testing, and system design to reduce regression risk and improve confidence in production deployments.
