Hi Jonah,
Thanks for the KIP!
I have two questions:
1. For the unclean recovery tool, what is the default option for the
automatic leader election? Looks like it is enabled by default? I wonder if
the default behavior can be:
- If all the replicas reply in time, do the auto leader election.
- Otherwise, output the replica log info for the operator to review.
2. For the kafka-elect-leaders, I wonder if it makes sense to also
include the broker epoch for the DESIGNATED election. Just in case the
broker fails before it is elected?
