MQ - 09 RabbitMQ的架构设计与实现

导图概述最基础的消息队列应该具备通信协议、网络模块、存储模块、生产者、消费者五个模块。接下来我们从消息和流的角度，分别看一下消息方向的消息队列 RabbitMQ、RocketMQ流方向的消息队列 Kafka、Pulsar在这五个模块的实现思路和设计思想。今天先看看 RabbitMQ。RabbitM...

RabbitMQ的架构设计

Broker：rabbitmq 的服务节点Queue：队列，是RabbitMQ的内部对象，用来存储信息。RabbitMQ消息只能存储在队列中。生产者投递消息到队列，消费者从队列中获取消息并消费。多个消费者可以订阅同一个队列，这时队列中的消息会被平均分摊（轮询）给多个消费者进行消费&#x...

RocketMQ 的基本概念、架构设计、特点以及适用场景

RocketMQ 是一款由阿里巴巴开发的分布式消息中间件，旨在提供高吞吐量、高可靠性的消息传递服务。它是一个可水平扩展的、具有低延迟和高可用性的分布式消息队列系统。本文将详细介绍 RocketMQ 的基本概念、架构设计、特点以及适用场景等。 1. 概念介绍 1.1 消息队列消息队列是一种在应用程序...

RocketMQ 整体架构设计

RocketMQ 整体架构设计整体的架构设计主要分为四大部分，分别是：Producer、Consumer、Broker、NameServer。为了更贴合实际，我画的都是集群部署，像 Broker 我还画了主从。Producer：就是消息生产者，可以集群部署。它会先和 NameServer 集群中的随...

RocketMQ核心架构设计思想（下）

同一个主题下的消费队列和消费者分配1、先对消费队列和消费者排序 2、消费者类似于页数、消费队列类似于所有记录数一个消费者所消费的消费队列类似第5页包含的记录数 3、消息队列分配策略算法（默认为：消息队列的平均分配算法）过滤分配到的消息的队列集合将分配到的消息队列集合与现有的集合做对比过滤掉失效...

RocketMQ核心架构设计思想（中）

Consumer负载均衡消息拉取线程在从服务器拉取到一批消息后然后提交到消息消费线程池后又马不停蹄的继续向服务器再次尝试拉取消息一个消费者可以同时消费一个topic下的不同队列1、在Consumer启动后它就会通过定时任务不断地向RocketMQ集群中的所有Broker实例发送心跳包（包...
