My apologies, if this should be non-sensical, but what would happen in the following scenario?
A leader election takes place in a three-server ensemble as the previous leader, s1, has been partitioned off. The previous leader had a later zxid than the remaining servers. The remaining servers exchange election notifications and elect s3 to be the new leader, form a quorum consisting of s2 and s3 and accept write requests. s1, zxid=4s2, zxid=3s3, zxid=3 Is it the case that at least one of s2 or s3 should have seen and agreed to the write leading to zxid=4 and that the new quorum will thus write zxid=4 first before handling other requests? -- Bruno
