Hi Joe Doliner, engineer at RethinkDB here. We've talked a lot about having support for an ODM. It will be happening but it's one of many things we want to add so I'm not certain of a timeline yet. I think the main thing we've discussed is an Active Record plugin. I'm not terribly well versed in the various ODMs that are out there and I'd be interested to know which ones you think are good and why if you wouldn't mind. It will help us in designing one that is awesome.

Well on their about page they have this guy listed: Michael Lucy (@mlucy) - Ruby drivers, protocol API, query execution

Might be a good place to start.

To compete with MongoDB for Node crowd, you need an ORM similar to Mongoose. It seems that Node users now default to MongoDB in their stack, much like MySQL in LAMP.

For Golang, mgo http://labix.org/mgo is a quality implementation driver for MongoDB. Hopefully there is something similar for RethinkDB.

We're working on improving the API spec so people can write clients easily (we'll publish an RFC soon).

As far as ORMs go, we do plan to do that, but it will take a little bit of time. It shouldn't be very difficult, so we hope to get to it soon.

Where did you get that from? CouchDB is what I've seen most used and suggested by far.
