Timo Walther created FLINK-9219:
-----------------------------------
Summary: Add support for OpenGIS features in Table & SQL API
Key: FLINK-9219
URL: https://issues.apache.org/jira/browse/FLINK-9219
Project: Flink
Issue Type: New Feature
Components: Table API & SQL
Reporter: Timo Walther
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, ST_Z
