title: How to create a set of user defined types using spring data cassandra?
body: <p>I am using Spring Data Cassandra 1.5.8.RELEASE to connect with my cassandra db 3.11.2.<br/><br/>
  I tried creating @Table pojo with a Set as a column field but it is throwing the following errors: <br/>
  user defined type not found, and<br/>
  some other cassandra mapping exceptions.<br/><br/>
  Can somebody help me in data modeling an 'Employee' table having a column that represents a set of Department UDTs? (Using spring boot, spring data cassandra 1.5.8+ and Apache cassandra 3.11.2+)</p>
