I see. What's the catch though. Sounds like free lunch. Is there some gotcha with partition tolerance?

- rubiquity 5y agoIt’s the case of 2F+1 versus F+1. Paxos/Raft offer fault tolerance where as other replication algorithms don’t. If you have a node failure in Primary-Backup or Chain for example you need to reconfigure before committing more writes. However in practice and certain environments reconfiguration can be faster than or the same as a leader failure in Paxos that requires running Phase 1 again.
