## Summary GeoPandas exposes `GeoSeries.hilbert_distance` and the corresponding GeoDataFrame active-geometry method for generating one-dimensional spatial-ordering keys from geometry-envelope midpoints. Sedona does not currently provide this API or a native SQL primitive with matching semantics. ## Proposed changes - Add a native `ST_HilbertDistance` scalar function backed by JTS, returning the full unsigned 32-bit address range as `Long`. - Expose the function in Spark, Flink, Snowflake `GEOMETRY`, and Snowflake `GEOGRAPHY` APIs. - Implement distributed `GeoSeries.hilbert_distance(total_bounds=None, level=16)` and GeoDataFrame delegation. - Infer default midpoint bounds with one distributed metadata aggregation while keeping all per-row results distributed. - Preserve GeoPandas index/name behavior and document Spark's signed `int64` representation. - Add cross-engine, parity, edge-case, and execution-plan tests plus SQL and GeoPandas documentation. No geometry rows should be collected on the driver and no Python UDF should be introduced. Part of #2230. -- This is an automated message from the Apache Git Service.
