Hi, Jiangjie, Thanks for bringing this up. A couple of quick thoughts.
1. If the throttle time is large, what can happen is that a consumer won't be able to heart beat to the group coordinator frequent enough. In that case, even with this KIP, it seems there could be frequent consumer group rebalances. 2. If we return a response immediately, for the consumer, do we return the requested data or an empty response? If we do the former, it may not protect against the case when there are multiple consumer instances associated with the same user/clientid.
