php高并发之php+go兑现actor模型(一)
php高并发之php+go实现actor模型(一)
传统的php代码,调用memcache api,mysql api都会被阻塞住,这是影响并发的一个瓶颈
?
而php本身不带线程,协程,这点不好优化,so,我想到用go语言,来做后端异步处理
?
为什么要用go?编译型,有动态语言特性,内置GC,简洁,高效,内置协程,提倡share by communicating
?
系统大致流程是这样
?
php需要异步的请求缓存,db时,均将请求的信息,发送消息,给后端的go.(可以采用消息队列,也可以用socket)
?
然后php干其他事情
?
后端go接受到请求,做相应处理,查询缓存啊,db啊之类
?
待php需要使用之前异步请求的缓存,db数据时,接收从后端go发回的结果消息...
?
系统的大致流程就是这样
