http://www.jdon.com/eda.html http://blog.csdn.net/gykimo/article/details/9182287 事件代表过去发生的事件,事件既是技术架构概念,也是业务概念.以事件为驱动的编程模型称为事件驱动架构EDA. EDA是一种以事件为媒介,实现组件或服务之间最大松耦合的方式.传统面向接口编程是以接口为媒介,实现调用接口者和接口实现者之间的解耦,但是这种解耦程度不是很高,如果接口发生变化,双方代码都需要变动,而事件驱动则是调用者和被调用者互相…

在微服务中使用领域事件   稍微回想一下计算机硬件的工作原理我们便不难发现,整个计算机的工作过程其实就是一个对事件的处理过程.当你点击鼠标.敲击键盘或者插上U盘时,计算机便以中断的形式处理各种外部事件.在软件开发领域,事件驱动架构(Event Driven Architecture,EDA)早已被开发者用于各种实践,典型的应用场景比如浏览器对用户输入的处理.消息机制以及SOA.最近几年重新进入开发者视野的响应式编程(Reactive Programming)更是将事件作为该编程模型中的一等公民.…

事件驱动模型 上节的问题: 协程:遇到IO操作就切换. 但什么时候切回去呢?怎么确定IO操作完了? 很多程序员可能会考虑使用“线程池”或“连接池”.“线程池”旨在减少创建和销毁线程的频率,其维持一定合理数量的线程,并让空闲的线程重新承担新的执行任务.“连接池”维持连接的缓存池,尽量重用已有的连接.减少创建和关闭连接的频率. 这两种技术都可以很好的降低系统开销,都被广泛应用很多大型系统,如websphere.tomcat和各种数据库等.但是,“线程池”和“连接池”技术也只是在一定程度上缓解了频繁调…
