为什么我不能增加session.timeout.ms? [英] Why can't I increase session.timeout.ms?

问题描述

我想增加 session.timeout.ms 以便允许更长的时间来处理在 poll()调用之间收到的消息.但是，当我将 session.timeout.ms 更改为高于30000的值时，它无法创建Consumer对象，并抛出以下错误.

I want to increase session.timeout.ms to allow longer time for processing the messages received between poll() calls. However when I change session.timeout.ms to a higher value than 30000, it fails to create Consumer object and throws below error.

谁能告诉我为什么我不能增加 session.timeout.ms 的值，或者我是否缺少某些东西?

Could anyone tell why can't I increase session.timeout.ms value or if I am missing something?

推荐答案

使用者会话超时的范围由代理 group.max.session.timeout.ms (默认30秒)和 group.min.session.timeout.ms (默认6秒).

The range of consumer session timeout is controlled by broker group.max.session.timeout.ms(default 30s) and group.min.session.timeout.ms(default 6s).

您应该首先在代理端增加group.max.session.timeout.ms，否则您将获得会话超时不在可接受的范围内".

You should increase group.max.session.timeout.ms first in broker side, otherwise you will get "The session timeout is not within an acceptable range.".
