卡夫卡消费者0.9是否向后兼容? [英] Is kafka consumer 0.9 backward compatible?

问题描述

即将到来的kafka消费者0.9.x是否将与0.8经纪人兼容?

Is the upcoming kafka consumer 0.9.x going to be compatible with 0.8 broker?

换句话说-可以只切换到新的消费者实施方式，而无需动手其他任何事情?

In other words - it is possible to only switch to new consumer implementation, without touching anything else?

推荐答案

根据 Kafka 0.9.0的文档，您不能使用新使用者来从0.8.x代理读取数据. 原因如下:

According to the documentation of Kafka 0.9.0, you can not use the new consumer for reading data from 0.8.x brokers. The reason is the following:

0.9.0.0与以前的版本相比，经纪人之间的协议有所更改.

0.9.0.0 has an inter-broker protocol change from previous versions.
