jiayuasu opened a new issue, #3164: URL: https://github.com/apache/sedona/issues/3164
Part of #2230. ## Summary Implement the GeoPandas-compatible `GeoSeries.constrained_delaunay_triangles` method and GeoDataFrame delegation by using Sedona's existing `ST_TriangulatePolygon` expression. The implementation must remain fully distributed. It must not call `to_geopandas()`, `collect()`, `toLocalIterator()`, or a Python row UDF. ## Requirements - Return a GeometryCollection of constrained Delaunay triangles for each polygonal input. - Match GeoPandas for Polygon and MultiPolygon geometries, including polygons with holes. - Match GeoPandas behavior for non-polygonal, empty, and null geometries. - Preserve the input index, CRS, and geometry SRID. - Support calls through both GeoSeries and GeoDataFrame. - Add API documentation and examples. ## Tests - Add direct tests for polygons, multipolygons, holes, non-polygonal geometries, empty geometries, nulls, index preservation, CRS/SRID preservation, and GeoDataFrame delegation. - Add version-gated GeoPandas parity tests for environments where `constrained_delaunay_triangles` is available. The existing Spark SQL function is sufficient; no JVM, Flink, Snowflake, or SQL wrapper changes should be necessary. -- This is an automated message from the Apache Git Service.
