Worked on the DSpace/DSpace repository to enhance data integrity for long-running background operations, focusing on BitstreamStorageService migrations and checksum processing. Addressed the risk of data loss by implementing commit-based checkpointing, ensuring that database changes persist even if processes are interrupted. Improved the reliability of the most_recent_checksum table by guaranteeing correct status updates during migration and checksum workflows. Developed integration tests to verify persistence under interruption, strengthening end-to-end migration resilience. Utilized Java for backend development, database management, and integration testing, delivering targeted bug fixes that lay the groundwork for safer, more reliable assetstore operations in production environments.
