Hi, nice work. I write a similar vector search extension https://github.com/1yefuwang1/vectorlite inspired by sqlite-vss using C++17 and hnswlib.

I'd like to do a benchmark to compare it with sqlite-vec, but I guess it is not a fair comparison given that sqlite-vec uses brute-force only.

One thing I'd recommend is to include recall rate in your benchmark data.

Brute force approach is a good starting point but doesn't scale with serious production workload.
