The original plan for HAMMER2 included multi-master synchronous replication. I don't know if that's still on the roadmap, or if something less ambitious is planned.

IIRC, years ago Dillon sold some proprietary synchronous multi-master replication product that provided ACID guarantees while also being relatively performant. (Because synchronous multi-master had historically been quite slow.) I always thought HAMMER2's replication model was going to be an evolution of that tech.

Dillon's database was called Backplane, and most of it was open source. I was always disappointed that he never (as far as I know) finished it, because it seemed very promising.
