Thanks! I've also been working on a non-SQL version as well. Will is right and wrong about SQL for Nostr. At scale, SQL does start to crumble. With a medium sized relay (or even semi high trafficked), it's completely fine when indices are used. But at the scale of what diVine was trying to do it wouldn't be the best performance. There were also a lot of things wrong from the beginning too where customizations were added, but accompanying indices not built for the filters/tags that would be used for every REQ.
