I didn't mean to imply that MySQL Replication was perfect. But I've been
using it for over three years with very few problems. And yes with
statement-based replication you can get some interesting replication
anomalies if you're not careful. But, that's true of any statement-based
replication with any database.

No, I'm aware of this basic builtin replication. It was rather
disappointing to see it moved out of the 8.4 release. We need something
more that just basic master-slave replication which is all this simple
builtin replication will provide. We need a real replication solution
that can handle statement-based and row-based replication. Multi-master
replication. Full cyclic replication chain setups. Simple master-slave
just doesn't cut it.

Ok, I just felt it should still be there. But, I hope development
understands just how important good replication really is.

I figured as much.
