Hi all, I just published KIP-415: Incremental Cooperative Rebalancing in Kafka Connect on the wiki here: https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals
This is the first KIP to suggest an implementation of incremental and cooperative rebalancing in the context of Kafka Connect. It aims to provide an adequate solution to the stop-the-world effect that occurs in a Connect cluster whenever a new connector configuration is submitted or a Connect Worker is added or removed from the cluster. Looking forward to your insightful feedback! Regards, Konstantine
