Redis Queue 介绍
RQ ( Redis Queue ) 是一个简单的 Python 库，用于实现作业的队列，并在后台进行处理。后端基于 Redis ，可方便集成到 Web
应用中，要求 Redis >= 2.6.0
示例代码：
from rq import Queue from redis import Redis from somewhere import count_words_at_url # Tell RQ what Redis connection to use redis_conn = Redis() q = Queue(connection=redis_conn) # no args implies the default queue # Delay execution of count_words_at_url('http://nvie.com') job = q.enqueue(count_words_at_url, 'http://nvie.com') print job.result # => None # Now, wait a while, until the worker is finished time.sleep(2) print job.result # => 889
后台作业处理 worker：
$ rqworker
*** Listening for work on default
Got count_words_at_url('http://nvie.com') from default
Job result = 818
*** Listening for work on default
