Hey @lucasbru , answering your questions : the new behaviour of the static membership regarding a member that joins with dup group instance Id is documented in [this](https://cwiki.apache.org/confluence/display/KAFKA/KIP-848%3A+The+Next+Generation+of+the+Consumer+Rebalance+Protocol#KIP848:TheNextGenerationoftheConsumerRebalanceProtocol-StaticMembership(KIP-345)) section of the KIP. We've also discussed it with @dajac and other client teams (librd), seeing the improvement the new protocol bring in this area (mainly in cases of conflicting members, that continuously kick each other out with the classic protocol) Your question does makes me notice that, even though the KIP describes how conflicting static members behave in the new protocol, it would probably be helpful extend that explanation to point out the fundamental difference it has with the legacy protocol and how it is an improved approach. (I can't find that explained in the KIP. If I'm not missing it, it would probably be a good update to the KIP [static membership section](https://cwiki.apache.org/confluence/display/KAFKA/KIP-848%3A+The+Next+Generation+of+the+Consumer+Rebalance+Protocol#KIP848:TheNextGenerationoftheConsumerRebalanceProtocol-StaticMembership(KIP-345)) @dajac ?)
