I have not used Arango in production although I evaluated it and exchanged a few emails with Claudius. I see a number of reasons why ArangoDB might be more interesting than Rethink: 1) Arango is a multi model database with graph, noSQL, and key-value pairs. Even if Rethink has joins and complex queries, it will never be as flexible for general data modelling. 2) Foxx is a logical layer on top of the database. While i…

Thanks! Are there any other noteworthy realtime DBs like Rethink and Firebase?

OrientDB has a similar feature called "live query".

Meteor also has something called "reactive data sources" although Meteor is not really a DB.

ArangoDB team is awesome, personally interacted with them a couple times.

As far as realtime and multi-model (graph) I work on https://github.com/amark/gun , which is also distributed and offline-first.

CouchDB's changes feed predates Rethink, I'm not sure why it largely gets ignored. Couch is rock solid.

For graph DBs, I've found nothing easier to setup and more efficient than Arango. The team there is very receptive and determined too.

I'd love it if Arango had a changes feed, but realistically it's really easy to just pipe the data into a stream from whereever gets confirmed writes to the database. This is how I've always done it outside of Couch/Rethink. It helps decouple the stream from the db concept in case more data sources or sinks are added later (very common in my experience).

I'm an ArangoDB team member. We are starting with our own Jepsen tests. But we will ask Aphyr as soon as possible to do an official test. In the meantime can the community check our implementation.

It most certainly makes sense to jepsen Arango before asking the public to do so. But I won't take your tests without a grain of salt till Aphyr does so. ;) Best of luck

As far as I know is Aphyer booked for months. We will do our best.

congratulations. Is there plan to support gremlin query natively ?

We are closely monitoring the development. Not being a Java database, we cannot run Java queries natively. Tinkerpop3 has added some hooks for non-Java, but it would still very hard to get the speed of AQL. But I hope that Tinkerpop will open up to non-Java even more.

Thanks. I understand the Tinkerpop JVM stack issue. They should have a native port as well.

Realm has the best implementation of live realtime updating objects/queries that I have tried, but the model is bit different from databases like Rethink in that it is an embedded database that you run locally (but which can then live sync with other instances).
