So is RethinkDB written in Lisp?

  No according the website it is written in C++.

    And yet the Clojure guy did his distributed DB in Clojure (aka, Lisp). Kind of makes me wonder why C++ was chosen...

      I've joined RethinkDB just a couple of months ago, so I might not have all the historical facts right, but here is what I know. In a previous incarnation RethinkDB was a highly optimized storage engine for SSDs implemented in C++ to be able to take full advantage of both low level SSD and kernel access. The current distributed engine was built on top on this storage engine and I think it only made sense to continue with C++.

        Originally, RethinkDB was to be a MySQL storage engine, which made C++ the natural choice. They pivoted away from MySQL after my short stint in the beginning so I can't speak to why the storage code was kept (though I can't imagine it's because my code was so great they couldn't bear to throw it away). Storage people tend to stick close to the metal, in general. This means C or C++ in most cases, for better or for worse.
