@Sandeeprao69 Are there specific methods of Mongo 4 that you are looking for, or is it not working all together?

[Sandeeprao69]

Hi @streleck I am looking for mongo db ACID Transaction which is introduced in version4. link

[streleck]

@Sandeeprao69 As in writing to multiple tables in a single transaction?

[sandeeprao691]

@streleck yup. That's what I want to achieve. I am using sails 1.0

I can review a PR that adds this to sails-mongo, as long as it uses the same approach that we use in the relational adapters

@mikermcneil @sandeeprao691 To support transactions, sails-mongo needs to be upgraded to at least 3.1.0 (https://docs.mongodb.com/manual/core/transactions/#transactions-and-mongodb-drivers). It would incur some changes internally (as sails-mongo right now uses "mongodb": "2.2.25")

It will include some probably incompatibility configuration changes (that could be handled by printing messages about it, auto migrating the configuration for the user).

During the update, https://github.com/mongodb/node-mongodb-native/blob/master/CHANGES_3.0.0.md should be checked to make sure that everything still works. and that we can start supporting sessions, transactions, etc.

I could start a new version supporting all of this. @mikermcneil as usual I might need your help/support on some topics.

@luislobo You bet- feel free to loop me in early on to talk through it. Would be good for me to get caught up anyway

@luislobo @mikermcneil Any idea when this might be released?

[Sandeeprao69]

@luislobo @mikermcneil Guys, can you please tell me when this might be released. If not soon can you guys please suggest a way to achieve transactions in mongo db using waterline.
