mongo可以自动删除收藏集吗? [英] Can mongo do autoremove collections?

问题描述

我听说mongo可以做到，但我找不到方法.mongo是否可以创建收藏夹，这些收藏夹会在将来设置的时间自动删除?还是Mongo无法做到这一点?

解决方案

mongodb无法自动删除集合，但可以自动删除BSON记录.您只需要在BSON record中存在的日期字段上设置ttl(生存时间)索引.您可以在此处 MongoDb:通过设置TTL从集合中删除数据

I heared, that mongo can do it, but I can't find how. Can mongo create collections, which will be autoremove in future, from time, which i can setup? Or Mongo can't do this magic?

解决方案

mongodb cannot auto remove collections but it can auto remove BSON records. You just need to set ttl(Time to live) index on a date field that exists in BSON record . You can read more here MongoDb: Expire Data from Collections by Setting TTL
