`AlterConsumerGroupOffsetsAsync` on unsubscribed topic but not empty group

Open plachor opened this issue 9 months ago • 1 comments

When we try to reset offset on unsubscribed topic for consumer group that is in stable state we end with AlterConsumerGroupOffsetsException (Error: Broker: Unknown member on partition level).

However AlterConsumerGroupOffsetsAsync does not state that group must be in empty state. Is it possible to allow offset rest on unsubscribed topics when consumer group is not in empty state?
