[源码解析] 并行分布式任务队列 Celery 之 多进程模型,Celery是一个简单、灵活且可靠的,处理大量消息的分布式系统,专注于实时处理的异步任务队列,同时也支持任务调度。因为Celery通过多进程来提高执行效率,所以本文将带领大家初步了解Celery之多进程架构和模型。

celery -A tasks.example worker -c 2 --l info 首先,会通过一系列的命令行解析的方法,提取出我们上面那个命令需要运行的模块 (即Worker 模块,具体流程因为过于复杂,就不展开讲了),解析到一个 Worker 的数据结构,并创建对应的实例,其中我们主要关注 start 方法。
