您好，首先感谢您的回复。
按照你说的，就是目前的4.x版本中。就算不做任何修改。broker部署的时候，填写每一个namesrv的ip。而生产者和客户端，就目前，也是可以使用lb负载到每一个namesrv的，对吧。
如果按照这个逻辑，也就是broker注册的时候，他会每次遍历所有的namesrv注册，对吧。

PushConsumerImpl -> PushSubscriptionSettings 类的 fifo 和 retryPolicy 默认值问题
真正的retryPolicy是把proxy的retry默认配置和客户端上报上来做了merge后产生的。客户端启动后把client

GitHub user xhrg edited a discussion: namesrv前面是否可以绑定LB？？？
如果我使用一个LB负载均衡器，转发到3个namesrv节点。这样肯定是有问题的。因为可能注册broker到namesrv-1节点，而读的时候，lb又可能把请求转发到namesrv-2节点。
如果我对namserv进行改造，实现彼此之间同步数据，那这样是否可以使用LB负载到三个节点。这样我在写namesrv的时候，可以使用域名的方式。
集群切换的时候会方便一些。

基本不会发生你说的情况。因为sdk发消息时，消息只会发到其中一个broker节点，但在极端场景下，可能同一个消息会发到多个Broker节点上，但在回查事务时，只要应用做好事务回查的幂等逻辑，也不会影响逻辑的正确性。

另外：如果主从不切换的话，在配置的时候只配置master就可以，如果主从切换的话，需要全配置（个人观点，不知道对不对）。

如何测试并计算Controller模式的RTO和RPO？
谢谢回复，
如何进一步测试呐？RPO是否可以理解为数据恢复的时间，是否可以用消费者来测试，启动消费者从消费异常，到消费正常这段时间表示RPO呐？

autoCreateTopicEnable=true is not work
我忘记在那个地方看到过，之前也有社区提出过这个问题，当时有人回复的是不建议支持，在实际生成环境中，都是建议关闭这个配置的。

感觉RocketMQ到5.0后，现在的proxy模式，开发文档上面有很多欠缺的，并且和dashboard有一些没有做好适配，dashboard又好长时间没有更新了。心塞啊

我使用的官方例子也出现了这个问题，解决了
1、play-docker.sh + sh mqbroker --enable-proxy
2、-p 8081:8081 说是 --enable-proxy 会自动启用 8081端口
3、我使用的是阿里云 所以安全组需要放行 8081
然后就搞定了

是检测在切换过程中是否有消息丢失？那怎么检测那？在切换过程中无法发消息，这段时间应该不用生成消息吧，就检测切换前和切换成功后这段是否有消息丢失？

RocketMQ5.1.3版本，为什么controller模式2主1从的性能比controller模式1主1从的性能低？
> 怎么会有2主1从，是不是1主2从，还是说是1主备 + 一个单主？
1主备+1主备，应该叫2主2从，同时注册到一组controller里面，并且同时注册到同一组namesrv中

检测切换前后消息是否有丢失？这个怎么检测呀！能给一个思路吗？切换前先预制一部分消息，然后看切换后看这些消息还在不在？
