MongoDB能同时插入或更新两个或多个collection吗？

Question

<code>这是collection a:
武功：["一阳指","九阴真经","辟邪剑谱"]

collection b:
主要技能： "一阳指"，
杀伤力："90"

这样我前台传来数据{技能："龙爪手"，
                   杀伤力："80"}

这个数据既要插入collecttion b
也要把技能：就是龙爪手更新到collection a的"武功"里
类似就b是a的子表

有什么能让他们关联到一起，一次插入而不用一个表一个表的插入。
因为有的字段可能关联多个collection。更新同理</code>

Answer 1

Sorry, original poster, I read it wrong. Mongo does not have such a thing as multi-table transactions. You’d better make it in the form of sub-objects within the table

Python has bulk_write, and most other languages ​​also have it
reqs=[pymongo.DeleteMany (the parameters are actually the same as the delete function), pymongo.UpdateOne (the parameters are actually the same as update_one), pymongo.Insert (same as above)]

database.conns.bulk_write(reqs)

Answer 2

It’s best not to divide the tables. . Mongo’s lock library level
