更多主节点的集群都支持,可以在rocketmq控制台上看看集群是否完好。
也可以在每个应用启动日志中看看是否拉取到相同的broker信息。

非常感谢您的回答,我尝试创建多个相同group的consumer去消费,发现单节点不会重复消费;当我使用双主双从集群模式的时候,两个consumer会出现重复消费的问题,请问是我使用的方式不正确吗

两个消费者,分开两个进程试试。如果问题消失,说明我们根据ip@pid的方式来做clientid

好的,谢谢,我试一下,如果我们只是单机部署,如何提升单个consumer的消费能力?
from newlife.rocketmq.
你的queue分片数,决定了消费线程数。理论上,更多的queue,就得到更多的消费线程,提升吞吐。
实际上绝大部分消费应用,瓶颈都在于消费到消息后的业务逻辑处理。

好的,谢谢您,不好意思,昨天的问题应该是我没研究明白,可以通过设置customer 的 InstanceName来解决,cliendid:ip@InstanceName

已解决,谢谢
