[Question] proper type for beam udf for complex types
Hi,
I'd like to use BeamSqlUdf-s with complex (potential nested) types. It is
not clear how to specify the type to achieve this.
Eg.: I've a rectangle with x,y,width,height and want to operate on this.
I'm getting this error:
No match found for function signature iou(<RecordType(INTEGER x, INTEGER y,
INTEGER width, INTEGER height)>) -> [Help 1]
So I'd like to have this type: RecordType(INTEGER x, INTEGER y, INTEGER
width, INTEGER height)>, how to specify this type in my UDF?
Thank you,
Gyorgy

This isn't supported. https://issues.apache.org/jira/browse/BEAM-11871
I believe you can get values with the WrappedRow type but that is an
internal interface (subject to change at any time) and doesn't expose
columns in a sensical way. (You can't access them by name and the indexes
are not stable.)
