--------------------------
Fix Version/s: 1.4.1
> Remove the locks from SnapshotPurge and SnapshotSetProperty APIs
> ----------------------------------------------------------------
>
> Key: HDDS-11137
> URL: https://issues.apache.org/jira/browse/HDDS-11137
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: OM
> Reporter: Hemant Kumar
> Assignee: Hemant Kumar
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.0.0, 1.4.1
>
>
> In HDDS-10590, we introduce the locks to achieve synchronization among
> snapshot purge, set snapshot property, and SSTFilteringService because they
> are updating the snapshotInfo table and might be causing the snapshot chain
> corruption because SSTFilteringService doesn't go through Ratis.
> In HDDS-11068, we found that the snapshot chain corruption issue still exists
> even after the locks. And the actual reason is that SSTFilteringService
> directly updates the DB and persists it. More details in HDDS-11068.
> Once we move sstFiltered flag out of snapshotInfoTable, we need to revisit
> the need for locks. We might not need locks after that and just rely on
> applyTransaction which is single threaded.
