Yes. To know the total number of consumers/streams in a group, you need to add up the number of streams on every consumer instance > For example, I have one broker with one partition.

Partition is the smallest granularity of consumption. This is because if we allow streams to share partitions, there will be a lot of distributed locking involved affecting throughput adversely.
