                 Key: HHH-5386
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5386
             Project: Hibernate Core
          Issue Type: New Feature
            Reporter: Bill DeCoste




 

-          Use case:  We'd like to be able to create custom unique identifiers (64-bit object IDs that take advantage of our domain space to provide compact UUIDs, for example).  We understand the PKClass functionality which allows us to get part of the way there, but we'd like to be able to combine this functionality with Hibernate's auto-increment functionality.

 

-          Something that's been contemplated here is an easy way to specify automatic hierarchical primary keys.  In other words if I have two entities, A and B, and B is ALWAYS an embedded entity of A, it'd be great to be able to tell Hibernate to structure the skill identifier as a compound PK composed of A ID and B ID.
