I have a circularly replicating MySQL cluster, and a newer cluster of Percona XtraDB instances that we're in the process of moving to. During the move, we're running some projects on the old cluster and other projects on the new cluster.
I'd like to have the old cluster replicate changes to most tables in one specific database across to the new cluster. Unfortunately, the binlog contains changes for every table in every database, and there doesn't seem to be a way to compile different sets of binlogs.
Is there a reasonable way to replicate only certain tables separately from pre-existing circular replication? The clusters are in separate datacenters with different providers, so I don't want to send the entire binlog over the wire when I only need a vanishingly small portion of it.
