The RethinkDB company went out of business last year, and unfortunately development has basically stopped, as you can see from the commits to their repo: https://github.com/rethinkdb/rethinkdb/graphs/contributors https://github.com/rethinkdb/rethinkdb/graphs/contributors The mailing list is also nearly dead with only a handful of posts total during 2017: https://groups.google.com/forum/m/#!forum/rethinkdb https://groups.google.com/forum/m/#!forum/rethinkdb RethinkDB did a lot of things right from an engineering perspective, but they were too late to market to compete with MonogDB; they burned through their cash, then went out of business, and now the devs work at various other companies (e.g., Stripe). RethinkDB is not a viable choice today. I personally put enormous effort into trying to use RethinkDB (and Cassandra, and also MongoDB); now I very happily use PostgreSQL. just like I did back in the 1999, and I’m very happy with PostgreSQL.
