Hey everyone, I'd like to start the discussion for KIP-589, part of the KIP-500 effort
https://cwiki.apache.org/confluence/display/KAFKA/KIP-589+Add+API+to+update+Replica+state+in+Controller This is a proposal to use a new RPC instead of ZooKeeper for notifying the controller of an offline replica. Please give a read and let me know your thoughts. Thanks! David
