Question about persisting master election result

[jivimberg]

I've noticed that a consequence of using the paxos chain to manage the master lease is that we end up with mixed application level and election level data in the log.

If we were to add a new parameter to def advance_instance in replicated_value.py so that the caller can specify if the value should be persisted to the log or not. And we'd keep track of the paxos instance number separately, so having it not matching the file length is not an issue. Do you see any disadvantage with this approach?

Is there any use case in where it'd be useful to read the election result from the log?
