RethinkDB leadership member here: happy to answer any questions for the next hour or so.

One thing to note, this was not an easy process; our team has spent months working daily on a solution. This was definitely our Plan A result, but we never expected LF to step up and provide the sponsorship funding as well. Huge thanks to LF/CNCF for helping close things in the end!

If you use RethinkDB please make sure to give a leadership member a hug if you happen to be in SF/NYC/Nashville/Philly/etc.
