Transaction pattern about mongodb-generic-repository HOT 9 OPEN

No this is still in the pipeline, I prioritized other issues.

Hi Rohana,

Thank you for your suggestion.

We could indeed implement a generic wrapper allowing you to define a 2 two phase commit transaction pattern.

The user would have to specify a rollback Action that would reset the state of both documents if something goes wrong.

Doing this in a generic fashion would also mean that a new type of base document should be added, in order to store pending transactions within the document in a generic way.
It could be something like a document implementing an interface like ITransactionalDocument, exposing a list of pending transactions.

I will have a look :)

Hi Alexandre,

Thanks for the answer!! But I was thinking about adding support to Mongo 4.0, which has transactions natively. :)

Sorry for the late reply I was away on holiday :)
Yes you are right, I will release it soon (in a week or so, I have already updated the driver to the latest version).

Hi @alexandre-spieser. Was this ever implemented?

Hi @alexandre-spieser
Is there a way to implement the transactions outside your generic implementation?

Thanks!

from mongodb-generic-repository.

Absolutely, you can override a lot of thing.
For the transaction bit, have a look at:
#21

eshkard supplied a zip file with some work around transactions.
You can base your work on that.

Hope this helps :)

Thanks @alexandre-spieser it really helped!
Do you have any plans to implement the transactions on your repository? If you coul'd put the mongodb transactions and the two-phase commit it will be a killer repo!

Thanks for the work!

Yeah I'll eventually get to it, it's just that integration testing it takes a LOT of time, and I've been working on other things lately.
Feel free to contribute though, it's open source for a reason :)
Thanks for the feedback! :)
