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).
