What happens when master fails? jganetsk mentioned Paxos, which you could use to reliably elect a new master. If I were evaluating your tech for usage at scale, I'd be pretty interested in failure modes, and pretty skeptical of anything that didn't employ distributed consensus. There may be other distributed consensus algorithms out there (one was apparently discovered in fruit fly cells [1]), but Paxos is the only one I've seen so far with a proof of eventual consistency.
