Yes, my company paid for RethinkDB over a year before they shut down. They sold support to us for $100, and of course their engineers did far more than $100 of bug fixing for us. The reality was that RethinkDB was a very difficult product to create and when you pushed it hard in production it had some serious bugs. The other core issue is that pretty much the same unique problem RethinkDB solved for us (data storage and changefeeds) could be much better solved using a different architecture and better database (PostgreSQL with LISTEN/NOTIFY). https://blog.cocalc.com/2017/02/09/rethinkdb-vs-postgres.html https://blog.cocalc.com/2017/02/09/rethinkdb-vs-postgres.htm...
