As for progress, it slowed down to non-existent during the handover period, and now seems to be picking up.
1. It's distributed. I can elastically add/remove nodes. I need this not so much for scalability, as for reliability, and I want to be future-proof.
2. Changefeeds. Nothing else even comes close, and my entire application is built around them.
I have no show-stoppers. The thing works. Sure, I'd love to see some things done differently (ReQL looks nice at a first glance, but has many limitations in practice, causing code that ends up being quite complex), but overall even if it were to stay exactly the way it is now, I'd continue using it.
not trying to judge anything as I no longer follow the project, but I think those numbers do tell the story.
To me focus on stability is the most important thing in a database so this makes me happy as an ops person, get it stable first and then if needed add more features. though i think rethinkdb is already quite feature complete.
