Description

Currently UDF implementations cannot create new UDT instances.

There's no way to create a new UT instance without having the com.datastax.driver.core.DataType to be able to call com.datastax.driver.core.UserType.newValue().

From a quick look into the related code in JavaUDF, DataType and UserType classes it looks fine to expose information about return and argument types via JavaUDF.

Have to find some solution for script UDFs - but feels doable, too.
