Bulk Insert/Delete
------------------
Key: HHH-6712
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6712
Project: Hibernate Core
Issue Type: New Feature
Components: core
Affects Versions: 4.0.0.CR4
Reporter: Martin Krüger
Deletion with cascade is done object by object now. When entity A references entity B and one deletes several objects A, then b1 is deleted then a1, b2 then a2, and so on.
It would be more performant if the bulk operation first deletes all b's and then deletes all a's.
This could be done by collecting the id's of the entities and then delete all entries in one table.
