KDBush is a high-performance static spatial index for 2D points built on a flat KD-tree, designed for scenarios where you need fast point-in-bounding-box or radius queries without the overhead of dynamic updates. It's ideal for developers working with large, static datasets who require fast spatial queries with minimal memory usage, such as GIS applications, mapping tools, or any system that needs to perform frequent proximity searches on point data.
