内容提要：  
本书覆盖了开发人员在落地分布式架构过程中使用RocketMQ 的主要技术点，包括RocketMQ 的 高性能通信渠道、生产消息、消费消息、存储消息、分布式事务消息、消息的可追踪性、消息的稳定性、消息的高并发、消息的高可用、消息的高性能和RocketMQ 5.x 的新特性。采用"是什么→怎么用→什么原理（源码分析）”的主线来讲解这些技术点。 本书的主要目标：①让读者在动手中学习，而不是"看书时好像全明白了，一动手却发现什么都不会”；②让读者掌握整个RocketMQ 生态的全栈技术和*佳实践，而不是只有RocketMQ 框架；③让读者从RocketMQ 体系化的视角熟悉RocketMQ 的核心原理，而不是零散且碎片化；④让读者成为消息中间件领域的技术专家或架构师，而不只是熟悉RocketMQ；⑤让读者具备自研消息中间件的能力，而不是仅停留在源码分析的层次，"授人以鱼，不如授人以渔”是本书*大的宗旨。 本书适合对分布式架构及支撑分布式架构落地的中间件感兴趣的技术开发人员。无论读者是否接触过 分布式消息中间件，只要具备一定的Java 开发基础，都能通过本书的学习快速掌握分布式架构中消息中间件的开发技能，并利用RocketMQ 消息中间件支撑分布式架构的落地。
