Hi,

>>   - If you wish to use UDT support with Cassandra please enable CQL3 before performing any operations.

How can I do the above in persistence.xml?

Right now I am using the following with each instance of EntityManager....

entityManager.setProperty("cql.version", CassandraConstants.CQL_VERSION_3_0);
