消息中间件系列教程（18） -RabbitMQ-基于RabbitMQ解决分布式事务（思想）

经典案例：以目前流行点外卖的案例，用户下单后，调用订单服务，让后订单服务调用派单系统通知送外卖人员送单，这时候订单系统与派单系统采用MQ异步通讯。RabbitMQ解决分布式事务原理：采用最终一致性原理。根据最终一致性，按派单流程提出问题，解决分布式事务：1.怎么保证订单...

跳槽高级开发就这么答：谈谈你对RocketMQ分布式事务原理的理解

有位工作五年的小伙伴在面试的时候被问到RocketMQ的分布式事务实现原理。他说他只知道RocketMQ能够支持事务，但是没有了解过它的事务实现原理。今天，我给大家分享一下我对这个问题的理解。1 分布式事务应用场景随着应用的拆分，从单体架构变成分布式架构，那么每个服务或者模块也会有自己的数据库。一个...

通过消息队列mq解决分布式事务问题的原理

公众号merlinsea核心利用队列的延迟特性，只有二次确认的消息才能被消费者监听使用。适用于上下游事务不保证实时一致性，但可以保证最终一致性的业务场景。原理通过mq实现分布式事务的最终一致性，其中消息生产者是分布式事务中的一个节点，消息消费者也是分布式事务的一个节点。当消息生产者往消息队列中投递消...

分布式事务解决方案之一：MQ异步确保事务

MQ解决通知型分布式事务1. 通知型事务(MQ)介绍分布式事务分为柔性事务和刚性事务，而柔性事务主要分为补偿型和通知型，补偿型事务又分：TCC、Saga；通知型事务分：MQ事务消息、最大努力通知型。补偿型事务都是同步的，通知型事务都是异步的。通知型事务的主流实现是通过MQ（消息队列）来...

SpringCloud基于RocketMQ实现分布式事务（文末送书）

前言分布式事务是在微服务开发中经常会遇到的一个问题，之前的文章中我们已经实现了利用Seata来实现强一致性事务，其实还有一种广为人知的方案就是利用消息队列来实现分布式事务，保证数据的最终一致性，也就是我们常说的柔性事务。消息队列实现分布式事务原理首先让我们来看一下基于消息队列实现分布式事务的原理方案...
