------------------------------------
Summary: Add metadata to consumer registry info
Key: KAFKA-2018
URL: https://issues.apache.org/jira/browse/KAFKA-2018
Project: Kafka
Issue Type: Sub-task
Reporter: Guozhang Wang
Assignee: Guozhang Wang
Fix For: 0.9.0
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.
