Fetch groups ------------ Key: HHH-13 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-13 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.1 rc3 Reporter: Adrien I don't like JDO at all, but it may have a good feature : the fetch groups. Instead of saying in each request which relations (or property now) I want to be fetch, I could says which fetch groups I want to be loaded. I will be usefull for complex objects will lot of relationship. Each fetch group will represent a view to the object. from Contract c left join fetch c.customer left join fetch c.items left join fetch c.foo ==> from Contract c left join fetch c.fetchGroup1 with : <many-to-one name="customer" fetch-group="fetchGroup1" /> <set name="items" fetch-group="fetchGroup1, fetchGroup2" > <many-to-one name="foo" fetch-group="fetchGroup1" /> Adrien
