Delete consumer group offset

Issue submitter TODO list

• I've searched for an already existing issues here
• I'm running a supported version of the application which is listed here and the feature is not present there

Is your proposal related to a problem?

When a consumer group no longer subscribe to a given topic, this topic stays in consumer group offsets.
One may want to explicitly delete those offsets, ex. otherwise monitor think lag is building up.

kafka-ui allows to reset offsets but not to delete them.

Describe the feature you're interested in

From a consumer group page, I would like to be able to delete one or several consumer group offsets.
UX could be very close to the reset offset page (topic + partion, drop reset type).

Describe alternatives you've considered

I currently have to do it manually using kafkactl delete consumer-group-offset ${COMSUMER-GROUP} --topic=${TOPIC}.

I'm not aware of any way of doing it with kafka-ui.

Just come across this same issue, where we subscribed to a topic by accident and removed the subscription, but a lag now shows on our dashboard. No worries i said, I'll pop into the UI and delete the offset for this consumer group. However, I can only update the offset or delete the consumer groups and its offsets to all topics its used. I kinda expected a delete button next to each topic, oh well, off to the command line.
