### Before Creating the Bug Report - [X] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq-clients/discussions). - [X] I have searched the [GitHub Issues](https://github.com/apache/rocketmq-clients/issues) and [GitHub Discussions](https://github.com/apache/rocketmq-clients/discussions) of this repository and believe that this is not a duplicate. - [X] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Programming Language of the Client Go ### Runtime Platform Environment centos ### RocketMQ Version of the Client/Server master ### Run or Compiler Version _No response_ ### Describe the Bug We have a broker cluster with 4 master nodes, and use go client simple consumer to consume. But we found that messages of broker-0 can't be received. ### Steps to Reproduce 1. Start up a multi-master cluster 2. Start up go client simple consumer, setting awaitDuration=20s 3. Produces certain messages. ### What Did You Expect to See? Receive all brokers' messages. ### What Did You See Instead? Messages of certain broker can't be received. ### Additional Context <img width="1269" alt="image" src="https://github.com/apache/rocketmq-clients/assets/103550934/2b6ea5ee-ec75-4749-a2bb-2dcef84a2ca5";> <img width="960" alt="image" src="https://github.com/apache/rocketmq-clients/assets/103550934/cf466faa-4ab8-445c-8a8a-98fe2f78de72";> 原因应该是在定时更新 topic 路由这里，判断路由是否变化时使用了 reflect.DeepEqual。因为 pb message 会包含一些额外的内部字段（比如 sizeCache），所以会误判成路由发生变化，就会导致 subscriptionLoadBalancer 的 index 每 30s 就会被重置，如果 broker 多节点且 pollingTime 比较长的话，就会出现某些 broker 一直不能被选中的情况。 -- This is an automated message from the Apache Git Service.
