Re: Question how to drop a unused group id?

[Vahid S Hashemian]

Hi Peyton,

Yes, if you'd like to change the value a broker restart is required for 
the change to take effect.

Hi Vahid,

Thank you very much for the reply, we use the kafka ver 2.11-0.10.2.1.

So when I apply the "offset.retention.minutes" to the system that request 
a restart to be effected?

Best Regards,
Peyton

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.
