> While working on the new consumer and the coordinator, I found there are some
> consumer metadata info that should better be kept track of. For example, in
> the new consumer the consumer id is assigned by the coordinator, which is
> just the group name + index, and we have lost useful information such as host
> name in the consumer id. Adding a metadata in the consumer registry info as
> we did in the consumer commit message would be very useful in this case.
> Since join group request protocol has not been exposed as the new consumer
> release, I think we can just change its format without bumping up request
> version. I am also wondering if a KIP is required for this change.
