Hey friends, I would like to start a discussion thread for a low-hanging fruit KIP following up KIP-345<https://cwiki.apache.org/confluence/display/KAFKA/KIP-345%3A+Introduce+static+membership+protocol+to+reduce+consumer+rebalances> here:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-469%3A+Pre-registration+support+for+static+members The goal is to pre-allocate static members to reduce unnecessary rebalances during cluster scale up. Let me know your thoughts, thank you!
