Review comment:
We are counting UpdateTableStats or UpdatePartStats events and not every
event. So, we will fail only after encountering no of tables/2 events of those
types. So it can not fail before applying update stats events. But to be on the
safer side, I have changed the code to fail after second event so that we have
at least one successful application before we fail. Since we are performing
multiple insert events per table, we can be sure that there are at least 2
events of each type.

> Transactional tables require a writeID associated with the stats update. This
> writeId needs to be in sync with the writeId on the source and hence needs to
> be replicated from the source.
