Subject Re: [DISCUSS] KIP-219 - Improve Quota Communication
Date Fri, 03 Nov 2017 17:28:03 GMT
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

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.
