It isn't a small unavailability, it's an unavailability of the whole replica. If you don't have a lot of data then it's the whole cluster :)
Of cause, we can introduce something like virtual replicas and eventually end up with a replica per key which is almost a Single Decree Paxos but with an overhead on log compaction and snapshotting.
- cube2222 10y agoWell, the unavailability is around 1/(number of machines in cluster) with a sufficient amount of replicas. That said, it's small relative to a whole-cluster unavailability and with small leader timeouts, it gets much better than you described in your article. Btw, thanks for answering my comments actively, I really appreciate it!
