[jira] [Created] (SENTRY-2307) Avoid HMS event synchronization while sentry is fetching full snapshot.

kalyan kumar kalvagadda created SENTRY-2307:
-----------------------------------------------

             Summary: Avoid HMS event synchronization while sentry is fetching full snapshot. 
                 Key: SENTRY-2307
                 URL: https://issues.apache.org/jira/browse/SENTRY-2307
             Project: Sentry
          Issue Type: Sub-task
          Components: Sentry
    Affects Versions: 2.1.0
            Reporter: kalyan kumar kalvagadda


Sentry tries to synchronize the HMS operations to make sure that sentry server process the notifications for create/drop/alter table and databases before it receives permission grants/revokes on them. Blocking HMS threads to make sentry processes appropriate notifications makes sense but doing the same when full snapshot is taken doesn’t serve any purpose as sentry server doesn’t update sentry permissions based on HMS full snapshot. We can document that there sentry could have some stale permissions  when there are any DDL operations performed at the time of snapshot creation.
