Review comment:
I think, in replication flow and for transactional table, the 2nd condition
should be true. If no valid writeId obtained from source, then need to fail. We
cannot fall back to default logic.

> 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.
