[Python]利用ZooKeeper构建分布式定时任务
本文涉及的源代码路径：https://github.com/xiaoquqi/openstackclient-demo/tree/master/tooz 一、目前现状及存在的问题 在实际业务系统中，经常有需要定时执行的任务，例如任务状态的定时更新、定时发送状态信息等。在我们的云迁移产品中，允许用户可以设定周期同步规则，定期执行数据同步并调用云平台接口执行快照操作。在单机版本中，通常在同一时间点并发任务量较少的情况下，问题并不是很突出，但是随着我们将云迁移服务从单机版本改造为平台版本后，当多个用户的多台主机同时触发快照任务时，一方面传统的设计方式就成为了瓶颈，无法保证用户的同步任务在同一时间点被触发（需要排队）；另外一方面，目前Active-Passive（简称AP方式）的高可靠部署方式无法利用集群横向扩展能力，无法满足高并发的要求。

使用MongoDB作为Salt Pillar后端存储数据
今天在查找salt中pillar嵌套pillar的方法时，无意之间发现了pillar除了可以直接使用文件(sls)外，也同时支持多种后端的数据存储方式。例如：MySQL, MongoDB, Ldap, json, cobbler甚至是puppet。这无疑为开发中的接口提供了极大的便利。
