> I'm sure I'm missing something, but why can't Raft send an empty
LeaderAndEpoch when it transitions to resigned?
I don't want raft to forget or expose forgotten state. At one point raft
knew that the leader was Y at epoch X. Later for the same epoch raft would
report that the leader is unknown for epoch X. I don't want for raft to expose
that it forgot that the leader was Y at epoch X. You can thinking of this as
lost of data. Raft needs to stay at epoch X because it is resigning. The
expectation is that some other voter will increase the epoch to X + 1 and try
to win the election.
