@joepie91 It got forked by the community as "RebirthDB" due to stagnation according to the Wikipedia page, then the fork got merged back into the original repo. I suspect all the stuff from RethinkDB the company is probably way out of date.
@freakazoid The commit graph is unfortunately also not looking very healthy: https://github.com/rethinkdb/rethinkdb/commits/main/
@freakazoid It doesn't seem to have any of the typical hallmarks of a CNCF project either, that I would expect - no branding, no changed header/footer on the site, no repository move, nothing. I wonder if the integration ever actually completed.
@joepie91 Makes me wonder why the CNCF even bothered buying it. Doesn't seem like a great use of funds.
