I feel like the lede is a bit buried here, bordering on deceptive.

That or the architecture doc is wrong. Both plausible I guess, in this day and age.

Hello, the developer of db9 here. You’re right, that section is indeed a bit too brief. We will add more architecture documentation later. What I wanted to convey is that, unlike a standard PostgreSQL, db9 is more like a pg SQL-compatible layer built on top of a large distributed KV store. I also shared a brief introduction in this tweet, which might help clarify things. https://x.com/dxhuang/status/2032016443114733744

If you're using TiKV why not use TiDB too, which is MySQL compatible?

I think what’s really interesting is that the first version of db9.ai is done by a single person by commanding AI. There must be tons of invaluable lessons learned.

AI is an instant turnoff and should be banned from HN. Unfortunately it is artificially promoted because of @sama despite not only providing no value but also making the world worse.

Wonder if that’s what it is, with a few changes to make it postgres wire compatible
