推荐答案

从3.2版开始，MongoDB没有内置的cronjob系统(TTL索引自动删除作业除外，但是这些无法帮助您解决此问题)问题).

As of version 3.2 MongoDB has no buildin cronjob system (with the exception of the TTL index auto-delete jobs, but these won't help you to solve this problem).

这意味着您将必须使用外部工具以查询作为参数启动mongo shell.有无数工具可用于此目的，一些工具可直接使用在所有常见操作系统中，而某些工具则以第三方工具的形式提供.列出所有选项的方法太多了，哪一种是最好的取决于您的IT基础架构以及系统管理员的喜好.

That means you will have to use an external tool to start the mongo shell with your query as a parameter to it. There are countless tools available for this, some build into all common operating systems out-of-the box and some in form of 3rd party tools. There are far too many options to list them all and which one is the best depends on your IT infrastructure and what your system administrators prefer.
