Jayson commented on HHH-1:
--------------------------

 I'm using spring + hibernate and I saw this method in one of the hibernate classes, 
public void saveOrUpdateAll(java.util.Collection collection) throws org.springframework.dao.DataAccessException.

How does this work? Thanks!

> 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.
