> This is the case where the events were deleted on source because of old event
> purging and hence min(source event id) > target event id (last replicated
> event id).
> Repl dump should fail in this case so that user can drop the database and
> bootstrap again.
> Cleaner thread is concurrently removing the expired events from
> NOTIFICATION_LOG table. So, it is necessary to check if the current dump
> missed any event while dumping. After fetching events in batches, we shall
> check if it is fetched in contiguous sequence of event id. If it is not in
> contiguous sequence, then likely some events missed in the dump and hence
> throw error.
