[jira] [Created] (SENTRY-2106) Sentry ahead full snapshot retry logic

Arjun Mishra created SENTRY-2106:
------------------------------------

             Summary: Sentry ahead full snapshot retry logic
                 Key: SENTRY-2106
                 URL: https://issues.apache.org/jira/browse/SENTRY-2106
             Project: Sentry
          Issue Type: New Feature
          Components: Sentry
    Affects Versions: 2.1.0
            Reporter: Arjun Mishra
            Assignee: Arjun Mishra
             Fix For: 2.1.0


Once SentryHMSNotification table is not empty, there are two cases when a full snapshot is triggered.
# If first event in list of notifications received from HMS greater than latest sentry hms notification Id
# If latest sentry notification Id is greater than current hms notification Id

The later is a unexpected case where for some reason sentry gets ahead of HMS. We should add a logic to trigger a full snapshot in case 2 only after a configurable number of retries. This will avoid  unnecessary full snapshot triggers as they are resource intensive
