No. It's certainly not correct for persistent IDs. It's not good for lots of other things.

Databases don't by and large do multi-master, they do master/slave. That's a single point of failure. That's really the main problem with it.

There was a note recently about using "eventually consistent" databases, and that's essentially (I think) close to multi-master. But that model does not work for persistent ID storage. That's really all I'm trying to say.
