Hi Peyton, What version of Kafka are you using? Starting from version 1.1.0 there is a DELETE_GROUP API: https://cwiki.apache.org/confluence/display/KAFKA/KIP-229%3A+DeleteGroups+API You can also use the consumer group command with `--delete` to delete a group.
For prior versions, the safest option would be to wait for `offset.retention.minutes` until all group offsets are expired. --Vahid From: "ÅíÅô(Peyton)" <p...@webull.com> To: users@kafka.apache.org Cc: "彭鹏" <p...@webull.com> Date: 08/13/2018 08:12 AM Subject: Question how to drop a unused group id?
