Does Kafka support topic level group.id?

[XinYi Long <xi...@skspruce.net>]

Hi, guys,

    ?

    My consumers want to share the data of one topic, so they use the same group.id. And the meanwhile, they also want to read every single messages of another topic, so they use unique group.id.
    Does Kafka support this situation? Or I need to create different consumers for different group.id?

Appreciate your reply.

Hi XinYi,

All consumer instances using the same group.id will share the data
(partitions) of a certain topic. The consumer group.id is not bound to a
topic.
If you want to share data on 1 topic, and parallel process data on another,
you have to change the group.id.

best regards,
Joris
