Hi Andrew, Thanks for taking the time to review this KIP! AS1. That makes sense. I've updated the KIP to use GROUP-INSTANCE-ID as the column header and to display the column only when at least one group member has a non-empty instance ID, consistent with kafka-consumer-group.sh
When you get a chance, Please take another look! Best regards, Sanghyeok An. 2026년 8월 9일 (일) 오후 4:48, Andrew Schofield <[email protected]>님이 작성: > Hi, > Thanks for the KIP.
