Aug 1, 2025Monthly summary for 2025-08: Delivered key observability, data integrity, and lifecycle improvements in the apache/ozone codebase. Implemented real-time deletion metrics in the Ozone Manager Web UI, ensured robust cleanup during snapshot purge by removing both the YAML data files and the snapshot directories, and refactored the snapshot creation purge to comprehensively delete keys across tables. These changes enhance operator visibility, reliability, and data consistency, driving lower maintenance costs and safer snapshot lifecycles.
