Re: [hibernate-dev] Configuration to support batching (or sorting) of DELETE statements efficiently

This must be done like insert but in reverse order. With inserts, we need to add parents first and children after, because of the foreign key constraints. For delete, we need to group children first and delete them prior to deleting parents. Is there something that prevents us from implementing this feature?
