Jan 1, 2025January 2025 monthly summary for CBIIT/HPC_DME_APIs focusing on release readiness, data migration reliability, and observability improvements. Key deliverables include hygiene and release-process enhancements (IDE gitignore updates and a 3.9.1 version bump across POMs) to streamline release readiness; data migration enhancements (API defaults for optional parameters and updated migration scripts) to simplify migrations; and diagnostics/logging improvements to aid troubleshooting for multipart uploads. Major bugs fixed included a null source-size NPE during data object metadata migration and a log formatting bug in HpcSystemBusServiceImpl, reducing runtime errors and noisy logs. Overall impact: faster, safer releases with fewer migration issues, improved operational visibility, and better support coverage for production incidents. Technologies demonstrated include Java, Maven-based release management, API design, data migration tooling, robust error handling, and enhanced logging.
