> When users are using group management, if they call consumer.subscribe() to 
> change the subscription, the removed subscriptions will be immediately 
> removed and their offset will not be commit. Also the revoked partitions 
> passed to the ConsumerRebalanceListener.onPartitionsRevoked() will not 
> include those partitions.
