It seems the changes to MongoDb in version 2.6 have also broken the run-rs package (see https://www.npmjs.com/package/run-rs ), which is simulating the replica set behavior of 3 nodes that you have in your MongoDb production environment (hopefully), especially on Atlas. The problem seems to be the u…

Seems like this is not an issue that needs to be solved in meteor. It must be solved in the npm package that you are using

Hmh, what makes you come to this conclusion? So it’s ok to just upgrade the MongoDb driver in Meteor and not care about many problems in npm packages or apps? I still don’t understand why this was pushed/necessary, I guess it’s also ok that I will just continue to be stuck on version 2.5.8 forever. …

So you mean, you want upgrades to be stuck and stop using upgraded versions of packages being used by meteor just because one of the tools that you are using, which is not even being used by meteor, is not working on the upgraded packages? :man_facepalming:

Also, check if you are referring to mongodb version or mongodb DRIVER version

Using the raw mongodb driver does not require the use of replicas. And again, check if you are referring to Mongodb (the database) version or the DRIVER version. You seem to be mixing the two

I agree with @rjdavid that this is not a Meteor problem. This is a 3rd party package, that does not work with MongoDB 4.4 (released about two years ago). However, my question is: why were you using it in the first place? Meteor sets up a single-node replica set automatically, so all of the replica …

[image] radekmie: However, my question is: why were you using it in the first place? Meteor sets up a single-node replica set automatically, so all of the replica set-specific features (e.g., change streams) just work. That doesn’t simulate the change of nodes (electing a new primary node). B…

[image] MongoDB 5.0 is out core FYI - MongoDb will change cluster automatically to MongoDb 5.0 in early February 2022 according to an email from them from 3/11/21 So yes, we do need support in Meteor for MongoDb 5.0

[image] a4xrbj1: That doesn’t simulate the change of nodes (electing a new primary node). The one from Meteor doesn’t, but you can set up as many nodes as you want using Docker. [image] a4xrbj1: It’s also very good as one app uses two different databases which works just fine with MongoD…
