      Description

      CALCITE-1968 added core functionality for handling spatial/geographical/geometry data. It should not be too hard to expose these features also in Flink's Table & SQL API. We would need a new GEOMETRY data type and connect the function APIs.

      Right now the following functions are supported by Calcite:

      ST_AsText, ST_AsWKT, ST_Boundary, ST_Buffer, ST_Contains, ST_ContainsProperly, ST_Crosses, ST_Disjoint, ST_Distance, ST_DWithin, ST_Envelope, ST_EnvelopesIntersect, ST_Equals, ST_GeometryType, ST_GeometryTypeCode, ST_GeomFromText, ST_Intersects, ST_Is3D, ST_LineFromText, ST_MakeLine, ST_MakePoint, ST_MLineFromText, ST_MPointFromText, ST_MPolyFromText, ST_Overlaps, ST_Point, ST_PointFromText, ST_PolyFromText, ST_SetSRID, ST_Touches, ST_Transform, ST_Union, ST_Within, ST_Z
