topics load balancing within a consumer group

Hi,

I have a question regarding load balancing within a consumer group.

Say I have a consumer group of 4 consumers which subscribe to 4 topics ,
each of which have one partition. Will there be rebalancing happening on
topic level ? Or I will expect consumer 1 have all the data ?

Currently, we distribute partitions to consumers on a per topic basis. So,
in your cases, consumer 1 will get all the data.

Thanks,

Jun
