[DISCUSS] KIP-211: Revise Expiration Semantics of Consumer Group Offsets

Hi all,

I created a KIP to address the group offset expiration issue reported in 
KAFKA-4682:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-211%3A+Revise+Expiration+Semantics+of+Consumer+Group+Offsets

Your feedback is welcome!

Thanks.

I think it would be helpful to clarify what happens if consumers rejoin an empty group. I would presume that the expiration timer is stopped and reset back to offsets.retention.minutes when it is empty again but the KIP doesn't say.

Thanks Thomas for the suggestion.
I updated the KIP to explicitly describe that situation.
