What an impressive release!
It makes me very curious.
Delivered to GitHub fully-formed: A grand total of 9 commits (mostly docs and CI fixes), all in the last 5 hours, and v0.1.0 released 3 hours ago.
No external database/storage-layer dependencies, so it's not "just" a CLI/server/parser wrapper around other libraries doing the "real work".
It appears to have a substantial test suite (76% code coverage, not skipping the scary bits), and great documentation.
There's a bit of context on https://github.com/stoolap but not much else about the author, project goals, relationship to other systems, e.g. it could be the data layer for something else.
(Interestingly, there's an archived stoolap-go repo with a very similar Go implementation of a columnar/hybrid database, so this is not the author's "first draft".)
Can assume they worked on this last few months when they stopped development in the, now archived, Go attempt, but they scrapped the entire git history on publication. Still, even if consider heavy AI use, looks like they put quite the effort in this.
I too am curious how to the first commit came about: https://github.com/stoolap/stoolap/commit/768eb836de0ff072b8...
Note to owner: CI is broken.
