cool project, reminds me a bit of arangoDB, but here even more logic can be built into SQL, allowing to develop (almost) the whole backend logic into the DB. The main problem with this kind of technology is that you move logic from established programming languages (java, C#, go, ...) to something more exotic which only a few programmers know. The other problem is lock-in, if the project dies you have to rewrite all your backend.

I wish you success though, to the point where those issues I mentioned are no longer true.
