> queryTopicConsumeByWho This method checks the subscription relationship.
If you want to delete the group, the consumer will stop. After reading your
demo, you deleted the consumer without stopping it. This is a non-standard
operation. If you want to delete a group, it must be that the group is no
longer in use.
yes you are right , your response make me clear ("no longer in use "),
Everything seems ok if call DefaultMQPushConsumer#shutdown method.
But, if close the application without call DefaultMQPushConsumer#shutdown,
it will keep the relation of topic even if I delete the customer group later
I need more tests to confirm it
