Question

atomic transactions - managed mongodb

Hello,

according to digitalocean docs

in MongoDB, transactions can only be performed on MongoDB instances that are running as part of a larger cluster. This could either be a sharded database cluster or a replica set.

is this possible on managed mongo database? I want to use atomic operations on multiple collections that all needs to fail if any of them fails.

Do I need to activate two standby nodes to use this or is this available on any managed mongo db?

Thanks

Hi there,

I think that the documentation that you are referring to is for self-managed MongoDB clusters:

https://www.digitalocean.com/community/tutorials/how-to-use-transactions-in-mongodb

A self-managed MongoDB cluster is a cluster installed on a few Droplets as described in this tutorial here:

https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-ubuntu-20-04

As of the time being, the Managed MongoDB databases, do not offer read-only nodes:

Best,
