Introduction | 前言

随着信息技术的快速发展及互联网用户规模的急剧增长,计算机所存储的信息量正呈爆炸式增长,目前数据量已进入大规模和超大规模的海量数据时代,如何高效地存储、分析、处理和挖掘海量数据已成为技术研究领域的热点和难点问题。当前出现的云存储、分布式存储系统、NoSQL 数据库及列存储等前沿技术在海量数据的驱使下,正日新月异地向前发展,采用这些技术来处理大数据成为一种发展趋势。而如何采集和运营管理、分析这些数据也是大数据处理中一个至关重要的组成环节,这就需要相应的基础设施对其提供支持。在现代微服务化的分布式应用中,不同服务之间往往需要进行频繁而广泛的通信,我们可以把消息队列比作是一个存放消息的容器,当我们需要使用消息的时候可以取出消息供自己使用。

参考维基百科的定义,在计算机科学中,消息队列和邮箱是用于进程间通信(IPC)的软件工程组件,或用于同一进程内的线程间通信的软件工程组件。与标准的请求-应答模式的 RPC 相比,RPC 更强调点对点交互、强事务保证和延迟敏感的服务/应用之间的通信,消息队列则更关注于异步通信、内容投递。

消息队列作为服务/应用之间的通信中间件,可以起到业务耦合、广播消息、保证最终一致性以及错峰流控(克服短板瓶颈)等作用。这里所谓的消息,可以看做一个小的,自包含的,不可变的对象,包含某个时间点发生的某件事情的细节:它通常包含一个来自时钟的时间戳,以指明消息发生的时间。例如,发生的消息可能是用户采取的行动,例如查看页面或进行购买。它也可能来源于机器,例如对温度传感器或 CPU 利用率的周期性测量。一个消息由生产者(producer)(也称为 发布者(publisher)或发送者(sender))生成一次,然后可能由多个消费者(consumer)(订阅者(subscribers)或接收者(recipients))进行处理。
