[jira] [Updated] (HDDS-7873) [Snapshot] Prune backup SST files that can be expanded periodically

     [ https://issues.apache.org/jira/browse/HDDS-7873?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hemant Kumar updated HDDS-7873:
-------------------------------
    Description: Proactively remove the unnecessary SST files from the backup directory which are not needed to generate diff using compaction DAG.  (was: We will have a concept of oldest Snapshot with compaction history. We will support efficient Snapdiffs from snapshots as old as this oldest with compaction history. We will delete SST file nodes in the compaction DAG that will not be used in any SnapDiff since this oldest retained Snapshot.

We will continue to support SnapDiffs from older Snapshots as well. But they will iterate over all the keys in the namespace.)
