Show HN: I implemented a neural network in SQL

Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

xarray-sql bridges the gap between array-based scientific datasets (via Xarray) and SQL, enabling users to query multi-dimensional data using familiar relational operations. It's interesting because it demonstrates that many geospatial and climate analysis tasks can be expressed as SQL GROUP BY, JOIN, and window functions, with a DataFusion backend that pushes down filtering and projection to scale gracefully.

Target audience: data engineers, data scientists, geoscientists
