Thanks Hashemian. It's clear to me now 😊 ________________________________ 发件人: Vahid S Hashemian <vahidhashem...@us.ibm.com> 发送时间: 2017年9月7日 12:41 收件人: dev@kafka.apache.org 主题: Re: A quick question on StickyAssignor
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.
