在单个查询中从 mongo 中删除多个文档 [英] Remove multiple documents from mongo in a single query

问题描述

我有一个要删除的 mongo '_id' 列表.目前我正在这样做

I have a list of mongo '_id' which I want to delete. Currently I am doing this

# inactive_users -->  list of inactive users 
for item in inactive_users:
    db.users.remove({'_id' : item})

但我的问题是列表太大了......(可能会超过 100,000).所以查询列表中的每一项只会增加服务器的负载.是他们在 mongo 查询中传递整个列表的一种方式，这样我就不必一次又一次地触发查询.

but my problem is the list is too huge... (it might go 100,000 +). So querying for every item in list will only increase the load on server. Is their a way to pass the entire list in mongo query so that I dont have to fire query again and again.

谢谢

推荐答案

db.users.deleteMany({'_id':{'$in':inactive_users}})
