> A few community members have been working on a RethinkDB integration with Meteor and Volt, and we expect robust integrations to become available in the coming months.

If I'm understanding correctly, RethinkDB could be a drop in replacement for mongodb? What are the benefits to this replacement in the context of Meteor?

If you're a meteor user you probably wouldn't notice the differences early on because livequery does a phenomenal job abstracting all the hard work away. However, we anticipate two advantages in the later stages of app development.

Firstly, as the app scales, livequery has to work harder and harder. I don't know how good its scalability is at the moment, but I think it would be very hard to approach the scalability of the feeds built into the database.

Secondly, as we build feed support into more and more queries, you'll be able to get functionality unavailable in livequery, which will allow building more sophisticated realtime experiences than currently possible.

We're going to find out how all these components work together in practice in the next few months. I'm really looking forward to that!

For one thing, you're not tied to Mongo. Generally more choices is good.

As for real reasons: - ReQL, functional, composable, and declarative, is very nice to use

- Changefeeds

- (v1.16) Arbitrary query watching with changefeeds

- Ease of sharding/load-balancing

- (v1.16) dynamic server management through queries

- Awesome web admin API

- Actually saving stuff to disk (couldn't resist)
