> UDF is using FlinkTypeFactory to infer operand type while UDTF does not go
> through the same code path. This result in:
> {code:console}
> org.apache.flink.table.api.ValidationException: SQL validation failed. From
> line 1, column 38 to line 1, column 44: No match found for function signature
> func(<COMPOSITE(Row(f0: Integer, f1: String))>)
