Vova Vysotskyi updated DRILL-7867:
----------------------------------
Description: When the user introduces only a single UDF that accepts
nullable arguments, it should be possible to use that UDF for arguments with
the required data mode. (was: Introduce {{NullHandling.EMPTY_IF_NULL}} to be
used for UDFs that return {{ComplexWriter}}, so it wouldn't be required to
introduce two versions of UDF nor nullable and non-nullable inputs.)
> Allow using required arguments for functions with nullable parameters
