Quite impressive, and very honest, too. They provide a "When is RethinkDB not a good choice?" point, they provide a "stability report", and that report was a proper torture test, and they responded promptly to the issues raised by the Jepsen test. BTW I have no use for their db at the time, but if I did one day, I would pick RethinkDB in a heartbeat over all competitors.

The way RethinkDB crews co-operate over Github is fantastic. Every workflow is tru github and you can transparently see their operation. I learnt a lot from that and i apply that to my team. We are building "A Killer" Communication tool using RethinkDB + HTML5. We will be announcing soon.

Can you give an example how their cooperation over Github is special?

I am with @pest . rethinkdb's github issues becomes my daily read, along with Github's Atom repo.

Just look at the issues , how they handle them , how their professional responses , and how quick they resolves issues after issues with full co-operation between issue owner , users and contributor. They guide contributors as well. And it is really Addictive , be warned.

I really can't give you a concrete answer but I wanted to confirm what my GP said:

I must admit to being obsessed with their GitHub Issues for awhile. It was almost as addicting as HN or reddit to check and read new issues and comments - I've probably read every major discussion and minor interaction they've had over the last year or more.
