This seems great, but I think until 4.2 they don't plan to have global point-in-time consistency - just per replica set. I wonder how this affects ACID semantics?

Also: This is going to be really nice, but I sure hope a major cloud provider starts providing a managed service. It's very nice having a managed service like Amazon RDS or Google Cloud SQL.

MongoDB has Atlas for managed services - https://www.mongodb.com/cloud/atlas

MongoDB Atlas is a cloud-hosted MongoDB service engineered and run by the same team that builds the database. It incorporates operational best practices we’ve learned from optimizing thousands of deployments across startups and the Fortune 100. Build on MongoDB Atlas with confidence, knowing you no longer need to worry about database management, setup and configuration, software patching, monitoring, backups, or operating a reliable, distributed database cluster.

Our team has been using both shared and dedicated plans at mLab https://www.mlab.com for almost a year now and we’re very happy with the ease of use and we’ve had zero problems so far.

That's awesome but these features will not likely be on mlab at launch. You may be best using MongoDB Atlas, which will include all 4.0 features.

Let's be honest, lacking behind a few months, especially if it is a major release, isn't a bad idea. With Rails apps in production I keep upto a year of distance to the major releases because there's so many rubygems that need to catch up or be replaced.

That's probably true. I think it took mLab a couple of months to support 3.6. But then again, having a major version release available at launch doesn't seem that important to me compared to all other database-as-a-service features.

Since you mentioned you work for MongoDB, if you guys could partner with Heroku and add Atlas to their official add-ons our team might be able to take a look and switch ;)

MongoDB Ops Manager [1] (previously MMS) is also quite nice, it's between Atlas and do-it-yourself.

FYI a OpenShift/K8s integration is now in beta:

Microsoft have something they claim is wire compatible: https://docs.microsoft.com/en-us/azure/cosmos-db/mongodb-int...

haha, mentioning RDS and SQL in a mongodb thread.

I actually witnessed that once when a customer (and mongodb user) had some man power from an agency allocated and one of those guys mentioned RDS. I wasn't impressed.

Well, I use SQL databases and MongoDB a lot, sometimes even in the same exact project. It turns out that while most data can be looked at as either relational or document-based with enough contortion, some of it leans fairly strongly in one direction.
