Arjun Mishra commented on SENTRY-2106:
--------------------------------------
More than roundtrip, the issue was getting inconsistent data from HMS
particularly HMS tables NOTIFICATION_LOG and NOTIFICATIONS_SEQUENCE seemed to
be out of sync. If HMS solves the problem, you are right this fix will not be
requred
> Remove sentry dependency on HMS table NOTIFICATION_SEQUENCE when checking if
> Sentry is out-of-sync with HMS

> 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 fix is to remove this dependency
>
> PLEASE NOTE THAT THIS SHOULD BE COMMITTED WITH SENTRY-2109
