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...

RocketMQ x OpenTelemetry 分布式全链路追踪最佳实践(3)

场景最佳实践目前，主流的云服务供应商都为 OpenTelemetry 提供了良好的支持，阿里云上的 SLS 和 ARMS 两款可观测产品都提供了基于 OpenTelemetry 的分布式全链路追踪服务。为了更好地展示分布式全链路追踪的过程，这里提供了一个代码示例：rocketmq-opentelem...

RocketMQ x OpenTelemetry 分布式全链路追踪最佳实践(2)

Messaging Span 定义Specifaition 中描述了 messaging span 的拓扑关系，包括代表消息发送、接收和处理的不同 span 之间的父子和链接关系。关于具体的定义可以参考：Semantic Conventions of Messaging。对应到 RocketMQ 中...

RocketMQ x OpenTelemetry 分布式全链路追踪最佳实践(1)

在分布式系统中，多个服务之间的交互涉及到复杂的网络通信和数据传输，其中每个服务可能由不同的团队或组织负责维护和开发。因此，在这样的环境下，当一个请求被发出并经过多个服务的处理后，如果出现了问题或错误，很难快速定位到根因。分布式全链路追踪技术则可以帮助我们解决这个问题，它能够跟踪和记录请求在系统中的传...

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...
