Oops, I see Markus Schiltknech likes the term "statement-based
replication" better too. Certainly master-slave communication using
"statement-based replication" has the same drawbacks as the broadcast
method, but I wanted to highlight that the broadcast was happening
outside the server. Do we need a master/slave "statement-based
replication" item and a middleware broadcast item?
