Robert Stupp updated CASSANDRA-10818:
-------------------------------------
    Status: Patch Available  (was: Open)

Patch introduces a {{UDFContext}} that allows to create UDT and tuple values for the return type, any argument type and by UDT name and tuple type definition.

> 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.
