 Review comment:
   itself is wrong. I do not see any ADDPROPS usage which is updating transactional properties.
All those seem to come through AddPartition and not alterTable for partitioned table. So,
may be we can safely mark this as non-transactional always. Does that look right?

> 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.
