[GitHub] [rocketmq] SchopenhauerZhang added a comment to the discussion: [5.1.0]关于Dledger和controller疑问

GitHub user SchopenhauerZhang added a comment to the discussion: [5.1.0]关于Dledger和controller疑问

mq 5.0 缺少Controller 主备自动切换的部署文档;尤其是DLedger模式升级到Controller 主备自动切换模式的文档;
仓库中这块相关的文档只有一下这段:
`
(2)原DLedger模式升级到Controller切换架构

由于原DLedger模式消息数据格式与Master-Slave下数据格式存在区别,不提供带数据原地升级的路径。在部署多组Broker的情况下,可以禁写某一组Broker一段时间(只要确认存量消息被全部消费即可,比如根据消息的保存时间来决定),然后清空store目录下除config/topics.json、subscriptionGroup.json下(保留topic和订阅关系的元数据)的其他文件后,进行空盘升级。
`
有时间可以补充下这块的详细文档吗?
quick start上也是controller+一主一从的模式(2个broker),并没有controller+1主2从(DLedger 模式)的quick start可供参考;
感谢。
