## Summary - Add `ST_ShortestLine(geom1, geom2)` function that returns the shortest LineString connecting two geometries - Uses JTS `DistanceOp.nearestPoints()` internally — same approach as the existing `ST_ClosestPoint` but returns both endpoints as a LineString instead of a single Point - Returns `null` for empty geometries Closes #2798 ## Changes ### Implementation (6 layers) - **Java core** (`Functions.java`): `shortestLine(Geometry, Geometry)` using `DistanceOp` - **Scala Expression** (`Functions.scala`): `ST_ShortestLine` case class - **Catalog** (`Catalog.scala`): Function registration - **Scala API** (`st_functions.scala`): Column/String wrappers - **Python API** (`st_functions.py`): Python wrapper - **Flink** (`Functions.java`, `Catalog.java`): Flink scalar function + registration ### Tests - Java unit tests (5 cases: point-to-point, point-to-linestring, polygon-to-polygon, empty geometry, same geometry) - Scala SQL tests + DataFrame API test - SRID preservation test - Python SQL test + DataFrame API test - Flink test ### Documentation - SQL, Flink, and Snowflake docs with examples ## Test plan - [x] Java unit tests pass (`mvn test -pl common -Dtest="FunctionsTest#shortestLine*"`) - [x] Python SQL tests pass - [x] Python DataFrame API tests pass - [ ] CI full test suite -- This is an automated message from the Apache Git Service.
