Hello! I would like to start this discussion thread on KIP-895: Dynamically refresh partition count of __consumer_offsets. The KIP proposes to alter brokers so that they refresh the partition count of __consumer_offsets used to determine group coordinators without requiring a rolling restart of the cluster. https://cwiki.apache.org/confluence/display/KAFKA/KIP-895%3A+Dynamically+refresh+partition+count+of+__consumer_offsets
Let me know your thoughts on the matter! Best,Christo
