Summary: Synchronization between Snapshot Deletes/GC and other
Snapshot jobs (read/diff)
Key: HDDS-8390
URL: https://issues.apache.org/jira/browse/HDDS-8390
Project: Apache Ozone
Issue Type: Sub-task
Components: Snapshot
Reporter: Prashant Pogde
We need to have proper synchronization between Snapshot delete/GC and other
Snapshot jobs e.g. reads from Snapshots and Snapdiff. Snapdiff is particularly
important case since it could be a long running job and in the middle of the
job, Snapshot delete/GC can kick in.
We should also have a uniform behavior in the cluster in case of a failover and
concurrent Snap-diff/Deletes. It should not happen that a leader OM node
returns certain result to a client but after a failover the new OM leader
returns different result.
