I'm not sure how the legal details play out, but it seems like they licensed their client drivers as Apache, so the intent seems to be that the AGPL is intended to make sure they get patches, even if you're selling hosted RethinkDB, not just using RethinkDB in your commercial SaaS software. Or at least that's what I gather from the FAQ https://rethinkdb.com/faq/
I don't know if this is a sound legal interpretation of the AGPL though. My obvious concern would be that the AGPL extends to the rest of our production code.
