> 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
> Labels: features
> Fix For: 2.1.0
>
> Attachments: SENTRY-2106.01.patch, SENTRY-2106.02.patch,

>
> After steady state, a full snapshot is triggered by mainly 2 cases
> # Sentry is "ahead"
> # Sentry is behind
> Case 1 has a dependency on NOTIFICATION_SEQUENCE table. This is not reliable
> as it was observed that sometimes NOTIFICATION_SEQUENCE and NOTIFICATION_LOG
> are not in sync. As a result of this unnecessary full snapshots can be
> triggered.
> The solution is to eliminate this check. Sentry can never be ahead of HMS.
