事件驱动架构(Event-Driven Architecture, EDA)是一种软件设计模式,它基于事件的产生、传播和处理进行系统的构建。事件驱动架构的核心思想是通过响应系统内部和外部的各种事件来触发逻辑操作。这种模式非常适…
Event- TheEventis the fundamental class unit of the event-driven system. It contains atype(such as "MARKET", "SIGNAL", "ORDER" or "FILL") that determines how it will be handled within the event-loop. Event Queue- The Event Queue is an in-memory Python Queue object that stores all of...
IO multiplexing就是我们说的select,poll,epoll,有些地方也称这种IO方式为event driven IO。 select/epoll的好处就在于单个process就可以同时处理多个网络连接的IO。 它的基本原理就是select,poll,epoll这个function会不断的轮询所负责的所有socket,当某个socket有数据到达了,就通知用户进程。 当用户进程调用了select,那么...
