RPC 通信与MQ 消息队列通信的微服务架构区别

基于 RPC 通信的微服务架构，其特点是一个服务依赖于其他服务返回的结果，只有依赖服务执行成功并返回后，这个服务才算调用成功。这种架构适用于用户请求是读请求的情况，就像下图所描述的那样，比如用户的一次 Feed API 请求，会调用 Feed RPC 获取关注人，调用 Card RPC 获取视频、文...

远程调用RPC和消息MQ区别

谈到消息队列，有必要看下RPC和MQ的本质区别，从两者的定义和定位来看，RPC（Remote Procedure Call）远程过程调用，主要解决远程通信间的问题，不需要了解底层网络的通信机制；消息队列（MQ）是一种能实现生产者到消费者单向通信的通信模型。核...

rabbitmq高并发RPC调用，你Get到了吗？

今天给大家介绍下rabbitmq中很重要的一个功能，RPC调用。RPC，即Remote Procedure Call的简称，也就是远程过程调用，是一种通过网络从远程计算机上请求服务，而不需要了解底层网络的技术。比如两台服务器上的A和B两个应用，需要进行服务接口的相互调用，我们就可以使用RPC实现。比...

RocketMQ源码分析-Rpc通信模块(remoting)二

前言今天继续RocketMQ-Rpc通信模块(remoting)的源码分析。上一章提到了主要的start()方法执行流程，如果有不清楚的地方可以一起讨论哈，这篇文章会继续解读主要方法，按照惯例先看看NettyRemotingAbstract的类图，看类图知方法。和NettyEventExecutor...

RocketMQ源码分析-Rpc通信模块(remoting)一

前言上篇文章分析了Rocketmq的nameServer的源码,在继续分析源码之前,先考虑一个问题,设计一个mq并且是高性能的mq最最核心的问题是什么,我个人认为主要是有俩个方面,1:消息的网络传输,2:消息的读写,这两个决定了mq的高性能。本文主要分析Rocketmq的网络通信部分,源码位于re...

RPC 用着好好的？为什么还需要使用 MQ？

阿粉之前看了一场架构师之路沈剑老师的一场直播，最近又重温了一下，根据自己的认知总结了一下，分享给大家。MQ 想必大家或多或少都用过，接入 MQ 之后的整体架构如下：可以看到使用 MQ 之后，上下游通信就变成图上的这种方式。这种跨进程的通信方式，我们还有一种常用的解决方案，使用 Dubb...

RocketMQ 的网络模型比 RPC 更加复杂，是一套有状态的网络交互，这主要体现在哪两点？

组队学架构之高并发架构系列：详解RPC远程调用和消息队列MQ的区别

RPC RPC（Remote Procedure Call）远程过程调用，主要解决远程通信间的问题，不需要了解底层网络的通信机制。 RPC框架知名度较高的有Thrift(FB的)、dubbo(阿里的)。 RPC的一般需要经历4个步骤： 1、建立通信首先要解决通讯的问题：即A机器想要调用B机器，首...
