I need to look at Datomic.

Zumero could also be described as having similar characteristics as Git. It's like a DVCS, except for stuff that looks like rows and columns instead of stuff that looks like directories and files.

I'm sure that any decentralized database violates ACID in some way, but Zumero is pretty darn ACIDic. All the local CRUD operations are ACID. And the sync to the server is ACID, or highly corrosive at minimum. But yes, the two operations are separate.
