Hi Hu Xi, This is a typo. It should read
if a consumer A has 2+ fewer topic partitions assigned to it compared to another consumer B, none of the topic partitions assigned to A can be assigned to B. For this assignor, the partition movement should not widen the existing balance gap among consumers. Thanks for catching it. I'll fix the typo in the KIP to avoid further confusion. --Vahid From: Hu Xi <huxi...@hotmail.com> To: "dev@kafka.apache.org" <dev@kafka.apache.org> Date: 09/06/2017 08:42 PM Subject: A quick question on StickyAssignor Hello Dev, I am a little confused about the statement below in KIP-54 (StickyAssignor things): * if a consumer A has 2+ fewer topic partitions assigned to it compared to another consumer B, none of the topic partitions assigned to B can be assigned to A. Is it a typo or do I misunderstand anything? Why partitions assigned to B cannot be reassigned to A in such a situation when A has fewer partitions than B? What're the thoughts under this design? Thanks.
