What is Xarray SQL?
This project provides a SQL interface for array datasets. Succinctly, we "pivot" Xarray Datasets to treat them like tables so we can run SQL queries against them (on the query engine of your choice). Any database with an ADBC driver (PostgreSQL, SQLite, Snowflake, BigQuery, ...) works too: xql.register ingests the Dataset into a table there, and xql.todataset(cursor, ...) brings results back.
From its README on GitHub
Xarray SQL (xarray-sql) is a launch on Show HN. It is written in Python and released under the Apache-2.0 license.
