       Body:
I also have problems understanding why mr. Bauer see this as secondary functionality, in a product being so good at persisting complex object model. For our application (national cadaster system for Norway) this feature is mandatory to be able to improve performance when persisting our object model (which is one of our major bottlenecks at the time). We deal with rather complex transaction, but nothing unusual.

        Key: HHH-1
    Summary: Optimize Hibernate for the bulk insertion of related entities
       Type: New Feature

     Status: Reopened
   Priority: Minor

 Original Estimate: Unknown
 Time Spent: Unknown
  Remaining: Unknown

    Project: Hibernate3
 Components: 
             core

Environment: Hibernate 1.2, MySql 3.1

Description:
It is currently difficult to batch the creation of persistent entities that maintain associations with other entities.

Add necessary api to hibernate to support the save or update of a collection of entities. An optimization can be applied in this scenario to group inserts / updates by entity class, or table. This will enable the hibernate engine to utilize batching if available, drastically improving performance over a network.
