title: Partially object loading in Hibernate
body: <p>I have a class that sometimes is not necessary to load fully. Can I load it partially, or I need to create light version of class (and new mappings for it)?</p>
  
  <p>For example: class <code>Message</code> with <code>id, title, body, author, timestamp</code>. When I want to delete message i need only two fields <code>id, author</code>.</p>
