事务可以与mongodb聚合$ merge一起使用吗? [英] Will transactions work with mongodb aggregation $merge?

问题描述

如果我使用mongodb事务同时更新两个文档.其中一个文档我想同时更新多个文档.我想使用mongodb聚合以某种方式构造文档. $ merge 是否会成为交易的一部分并更新所有文档，还是有可能失败?

If I am using a mongodb transaction to update two documents at the same time.One of the documents I would like to update numerous documents at the same time. And I want to use mongodb aggregation to structure the documents in a certain way. Will $merge be part of the transaction and update all docs or is there a posibility of failure?

推荐答案

没有交易将无法进行.根据mongodb docs db.collection.交易中允许使用aggregate()，但不包括 $ merge 阶段.在此处.

No the transaction will not work. According to mongodb docs db.collection.aggregate() is allowed in transaction but the $merge stage is excluded. See more here.
