I'll have to do some more reading about federated tables. However, I'm
thinking it might be easier to script the recovery process and integrate
the "is my master alive?" polling with my network/server monitoring system,
thus eliminating the need for the SQL scheduler. The SQL scheduler is really
cool sounding, but still beta.
I think that for now, I'm going to go with the A<->B->C scheme. I can move to
a fully circular scheme, later.
In the mean time, I have to migrate all of this from Postgres....
Take care and have fun,
