This article discusses the Hydronium Project, a complete rewrite of the H3 library in Rust, designed for better integration and performance. It highlights the goals of improving safety, speed, and API coverage while presenting testing methodologies and performance benchmarks against the original H3 implementation.

This article explains how Floe improves the performance of geo joins by using H3 indexes. Traditional spatial joins can be slow due to their quadratic complexity, but with H3, the process becomes a fast equi-join through a filtering step that reduces the number of candidates. The result is a significant speedup in geospatial queries.
