Sundar Sridharan
Worked on CorfuDB/CorfuDB, delivering backend features and stability improvements over three months. Developed a parallel table dump workflow in Java, enabling simultaneous export of multiple tables with JSON serialization and robust file handling, which streamlined data export processes. Enhanced the DynamicProtobufSerializer by exposing reusable API surfaces and adding integration tests, reducing code duplication and improving modularity in the serialization layer. Addressed a critical bug in the Compactor Liveness Validator by replacing a risky query approach with a safer iteration over table names, increasing reliability of liveness checks. Emphasized maintainability and correctness through targeted testing and thoughtful tooling enhancements throughout.

Mar 1, 2025March 2025: Delivered a critical correctness fix in the Compactor Liveness Validator for CorfuDB/CorfuDB, improving idle table counting accuracy and overall liveness checks. The patch replaces the risky executeQuery-based approach with an iteration over table names to fetch statuses, addressing the FJP-related bug and increasing stability during compaction. All work is traceable to commit 78a6edf850a5e16512b6701035f7e3dfd3cc1992.
