Alexander Kolbasov commented on SENTRY-1760:
--------------------------------------------
Full snapshot is very expensive as it now requires stop the world for hive - we
can't just do it willy-nilly, e.g. when Sentry crashed and decided to restart.
The case where Sentry thinks it is in front of notifications is interesting -
it most likely indicates that something is quite wrong and may be a good case
for forcing a full snapshot.
> HMSFollower should detect when a full snapshot from HMS is required

> The current criteria for getting a full snapshot from HMS is insufficient. We
> need to get full snapshot every time when there is a gap between last stored
> notification and the smallest notification available from HMS.
