发包QPS控制,有两个难点. 1. redis交互流量的限制. 假设每分钟有1000条流量任务生成,每条跑20个插件,每个插件发5个数据包,每分钟约发十万请求. 那么在发包处做QPS会遇到一个问题,如果每次发包时先问一下redis "这条流量在不在QPS限定范围内?如果在,这一秒这一分钟的QPS是否已经达到上限不能发送了?如果 没达到我就发送顺便redis这个域名当前秒发送量也+1", 至少每分钟与redis交互十万次以上,估计一下redis的kbps约提升10M以上. 之后会发现,该…

1.Celery模块调用 既然celery是一个分布式的任务调度模块,那么celery是如何和分布式挂钩呢,celery可以支持多台不通的计算机执行不同的任务或者相同的任务. 如果要说celery的分布式应用的话,就要提到celery的消息路由机制,AMQP协议.具体的可以查看AMQP的文档.简单地说就是可以有多个消息队列(Message Queue),不同的消息可以指定发送给不同的Message Queue,而这是通过Exchange来实现的.发送消息到Message Queue中时,可以指定…

celery retry时,将发送到原有的队列,并在任务中加入执行的时间,以及当前重试的次数. worker立刻读取该任务,同时记录一条[任务]到 unacked中,表示该任务在worker中还未执行. eyJleHBpcmVzIjogbnVsbCwgInV0YyI6IGZhbHNlLCAiYXJncyI6IFsiMTIzNCJdLCAiY2hvcmQiOiBudWxsLCAiY2FsbGJhY2tzIjogbnVsbCwgImVycmJhY2tzIjogbnVsbCwgInRhc2tzZXQi…

Given an increasing sequence S of N integers, the median is the number at the middle position. For example, the median of S1 = { 11, 12, 13, 14 } is 12, and the median of S2 = { 9, 10, 15, 16, 17 } is 15. The median of two sequences is defined to be…
