源码阅读技巧篇：RocketMQ DLedger 多副本即主从切换专栏回顾

RocketMQ DLedger 多副本即主从切换专栏总共包含9篇文章，时间跨度大概为2个月的时间，笔者觉得授人以鱼不如授人以渔，借以这个系列来展示该系列的创作始末，展示笔者阅读源码的技巧。首先在下决心研读 RocketMQ DLedger 多副本(主从切换)的源码之前，首先还是要通过官...

源码分析 RocketMQ DLedger 多副本即主从切换实现原理

DLedger 基于 raft 协议，故天然支持主从切换，即主节点(Leader)发生故障，会重新触发选主，在集群内再选举出新的主节点。RocketMQ 中主从同步，从节点不仅会从主节点同步数据，也会同步元数据，包含 topic 路由信息、消费进度、延迟队列处理队列、消费组订阅配置等信息。那主从切换...
