Vadim Spector commented on SENTRY-2109:
---------------------------------------

I think it's useful to have as many reviews as possible, so if [~akolb] wants 
to review it may be worth to reopen it.

[~spena], it is correct, for now this logic is going to be on hold, so there is 
no rush in committing it. Since it's almost complete (unless the remaining 
reviewers find something wrong), it can be a legitimate plan B, if HMS fix is 
found to have any serious issues.

> Fix the logic of identifying HMS out of Sync and handle gaps and 
> out-of-sequence notifications.

> Currently HMSFollower proactively checks if sentry is out of sync with HMS 
> and initiates full snapshot, if needed.
> There will be false positives with the current logic if there are gaps in the 
> event-id in the notification log sequence.
> This jira is aimed at making that logic robust.
