Limits
- You cannot delete the default consumer group provided by IoT Platform.
- If the consumer group is associated with an AMQP subscription, you must disassociate the consumer group from the subscription. If the subscription has multiple consumer groups, you can call the DeleteConsumerGroupSubscribeRelation operation to remove the consumer group from the subscription. If the subscription has only one consumer group, you can call the UpdateSubscribeRelation operation to change the consumer group or call the DeleteSubscribeRelation operation to delete the subscription.
