[Spark SQL]: Does Spark SQL 2.3+ suppor UDT?

[Suny Tyagi]

Hi Team,


I was going through this ticket
https://issues.apache.org/jira/browse/SPARK-7768?jql=text%20~%20%22public%20udt%22
and
could not understand that if spark support UDT in  2.3+ version in any
language (scala, python , java, R) ?

I have class something like this

Class Test{

        string name;

        int age;

}


And My UDF method is:

public Test UDFMethod(string name, int age){

           Test ob = new Test();

           ob.name = name;

           ob.age = age;

}

Sample Spark query-   `Select *, UDFMethod(name, age) From SomeTable;`

Now UDFMethod(name, age) will return Class Test object. So will this work
in Spark SQL after using SQLUserDefinedType tag and extending
UserDefinedType class.

 As UserDefinedType is private in Spark 2.0. I am just want to know if UDT
is support in Spark 2.3+. If yes what is the best to use UserDefinedType or
UDTRegisteration. As of now both are private.
