Creator of sqlite-vec here, happy to help debug anything if you do attempt to try out SQLite vector search again.

You mentioned "VSS" in another comment, which if that was my sqlite-vss extension, I more-or-less abandoned that extension for sqlite-vec last year. The VSS extension was more unstable and bloated (based on Faiss), but the new VEC extension is much more lightweight and easy to use (custom C vector functions). The new metadata column support is also pretty nice, and can be used for push-down filtering.

That being said, sqlite-vec still doesn't have ANN yet (but can brute-force ~10k's-100k of vectors quick enough), and I've fallen behind on updates and new releases. Hoping to push out a desperately-needed update this week

And there are a few other SQLite-based vector search extensions/tools out there, so the ecosystem is general might be worth another look.

Hey Alex - thanks for commenting. I'd be interested in giving this all another look. Like we mentioned in the post + comments, We went with redis because that's what got us the results we wanted. I'm open to revisiting our vector storage if it spares us needing to manage a separate db process.

Ended up swapping out redis for sqlite-vec. Works great. Thanks
