> 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:
> {code}
> 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,
> {code}
