[D] In controller mode, the transaction topic created will be lost after a master-slave switch of the Broker [rocketmq]
GitHub user dingsongjie created a discussion: In controller mode, the transaction topic created will be lost after a master-slave switch of the Broker
Version : 5.3.3
In controller mode, a transaction topic will be lost after a master-slave switch of the Broker. Through testing, I found that a topic created using mqadmin is only stored in the topics.json file on the master node and is not synchronized to the slave node. After a master-slave switch, the former slave becomes the new master, but the previously created topic is missing. I'm wondering if there's a misconfiguration on my side — shouldn't the topic information be stored in the controller in this mode?

I also encountered the same problem. After switching master and slave, the topic will disappear.
