第一篇: Python 神器 Celery 源码阅读 (1) 第二篇:Python 神器 Celery 源码阅读 (2) Celery是一款非常简单、灵活、可靠的分布式系统,可用于处理大量消息,并且提供了一整套操作此系统的工具。Celery 也是一款消息队列工具,可用于处理实时数据以及任务调度。
The 99.9 percentile and 99.93 percentile are a function of how quickly the system can recover after a delay. The higher the throughput, the less headroom the system has to recover from a delay. Double-buffering for contended writes When double-buffering is disabled, all writes to the queue ...
