[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2394) Support filter tag in subclass

[Welkin Hu (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2394?page=comments#action_25958 ] 

Welkin Hu commented on HHH-2394:
--------------------------------

Hibernate 3 does not supports filter tag in subclass (includes union-subclass, joined-subclass) yet. 
I think this feature is very useful. For example,  There is a class which includes many types and totally billions of records.
In this case I do not want create a root table for all types.  I rather to apply per concrete class per table strategy, create one abstract class and some union-subclass. 
I defined a filter for object's permission checking. Since every object type have its own table, I have to define the filter in each union-subclass. 

Is it correct?
