消息队列RocketMQ版主从切换

RocketMQ 平滑升级到主从切换实战

本文主要介绍如何将 RocketMQ 集群从原先的主从同步升级到主从切换。首先介绍与 DLedger 多副本即 RocketMQ 主从切换相关的核心配置属性，然后尝试搭建一个主从同步集群，再从原先的 RocketMQ 集群平滑升级到 DLedger 集群的示例，并简单测试一下主从切换功能。 1、R...

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...

RocketMQ 整合 DLedger(多副本)即主从切换实现平滑升级的设计技巧

源码分析 RocketMQ DLedger 多副本系列已经进行到第 8 篇了，前面的章节主要是介绍了基于 raft 协议的选主与日志复制，从本篇开始将开始关注如何将 DLedger 应用到 RocketMQ中。摘要：详细分析了RocketMQ DLedger 多副本(主从切换) 是如何整合到 Ro...
