Not necessarily. As long as your quorums always overlap you can have weaker commit requirements. See the FPaxos paper and some of Heidi Howard’s blogs for more on this.

FPaxos requires commit quorum and subsequent promise request quorum to intersect. It doesn't bring any significant thruput benefits


I didn't say FPaxos brought throughput benefits. I pointed out that you can still have a correct implementation without requiring majority quorums.

But since you brought it up, FPaxos can have both lower latency and higher throughput than MultiPaxos/Raft[0] ;)

Great link. Need to look into what WPaxos is.
