如何在mongo的交易中实现回滚？ [英] How to achieve rollback in transactions in mongo?

问题描述

在nodejs express服务器的请求和响应中，通常需要通过mongoose对mongodb进行查询。

在许多情况下，如果首先有几个查询执行成功，并且在一个事务处理中都会失败，那么可能会发生。

现在我需要回滚我的db状态到db的初始状态。

那么我怎么能在mongodb中有效地回滚？
请提供一些合适的参考。

解决方案

我同意Hector。如果您需要多个文档交易，那么Mongo可能不适合您。您可以将数据结构嵌入到单个文档中吗？那么你可以得到你正在寻找的回滚。

另一个选项是查看跨多个文档提供事务的Mongo克隆TokuMX。

I am using mongoose over mongodb.

In a request and response from nodejs express server, generally requires a no of queries to mongodb through mongoose.

In many cases it may happen, if first a few queries executes successfully and rest all failed under a transaction.

Now i need to rollback my db state to the very initial state of db.

So how can i rollback efficiently in mongodb? Please provide some suitable references.

解决方案

I agree with Hector. If you need multiple document transactions then Mongo might not be a good fit for you. Can you embed your data structure in a single document? Then you can get the rollback you are looking for.

Another option is to look at the Mongo clone TokuMX which provides transactions across multiple documents.
