mda's Introduction

MDA(devloping)

Message Driven Architecture

旨在让开发一个低延迟、高并发、高可用、基于消息驱动的响应式系统变得无比的简单。

最简单、最本质的开发模式

  • 接受哪些类型的消息 -- 命令/事件
  • 发出哪些类型的消息 -- 命令/事件

这就是你需要做的工作,就是这么简单,其他的事情,不用管,框架帮你搞定了,让你真正享受响应式DDD,仅仅处理领域问题!!!

特性

  1. 低延迟

    运用Event souring技术使整个业务处理部分完全运行在内存中。

  2. 高并发

    借鉴Actor model**,使用单线程技术处理整个业务逻辑,从源头解决并发问题。

  3. 高可用

    通过并行复制原始事件源数据到远程机器,实时同步领域状态,当本机业务处理器宕机时,可以实现秒级切换。这不仅比基于最近快照副本重放最新事件更快,而且也解决了单点故障的问题。
