If you're trying to have a table in multiple replication sets, that won't
work, and having multiple clusters will merely muddy matters.

If you introduce a second cluster to try to get around this, what you'll
discover is that the triggers for the second cluster are liable to
eliminate those set up for the first cluster, thereby breaking the first
replication set.
