RethinkDB user here. I've been running it in production for the last 8 years or so. It works. It doesn't lose data. It doesn't corrupt data (like most distributed databases do, read the Jepsen reports). I am worried about it being unmaintained. I do have some issues that are more smells than anything else — like things becoming slower after an uptime of around three weeks (I now reboot my systems every 14 days). I could also do with improved performance. I'm disappointed that the Winds of Internet Fashion haven't been kind to RethinkDB. It was always a much better proposition that, say, MongoDB, but got less publicity and sort of became marginalized. I guess correct and working are not that important. I'm slowly rebuilding my application to use FoundationDB. This lets me implement changefeeds, is a correct distributed database with fantastic guarantees (you get strict serializability in a fully distributed db!), and lets me avoid the unneeded serialization to/from JSON as a transport format.
