["Tyler Hobbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-10818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15042440#comment-15042440 ] 

Tyler Hobbs commented on CASSANDRA-10818:
-----------------------------------------

Our alternative is to use the new method for creating UDT values that will be introdued by [JAVA-1012|https://datastax-oss.atlassian.net/browse/JAVA-1012].  However, that might end up being more complicated for a user to work with.

> 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.
