Use Memcached for Java enterprise performance, Part 1: Architecture and setup

Memcached采用典型的Master-Worker模式,其核心思想是:有Master和Worker两类进程(线程)协同工作,Master进程负责接收和分配任务,Worker进程负责处理子任务.当各Worker进程将各个子任务处理完成后,将结果返回给Master进程,由Master进程做归纳和汇总. 工作示意图如下所示: 其中每个工作线程维护一个连接队列,以接收由主线程分配的客户连接:同时每个工作线程维护一个Libevent实例,以处理和主线程间的管道通信以及和客户连接间的socket通信事件

前面提到过Memcached的线程模型:Memcached使用Libevent,以此为基础来处理事件.其原理为:启动时的线程为main thread,它包含一个event_base,之后创建多个worker thread:每个work thread中也有一个event_base.main thread中的event_base负责监听网络,接收新连接:当建立连接后就把新连接交给worker thread来处理. Memcached的main函数在Memcached.c中.main函数中初始化了系统

Memcached是什么?Memcached是由Danga Interactive开发的,高性能的,分布式的内存对象缓存系统,用于在动态应用中减少数据库负载,提升访问速度. Memcached能缓存什么?通过在内存里维护一个统一的巨大的hash表,Memcached能够用来存储各种格式的数据,包括图像.视频.文件以及数据库检索的结果等.Memcached快么?非常快.Memcached使用了libevent(如果可以的话,在linux下使用epoll)来均衡任何数量的打开链接,使用非阻塞的网络I
