Hibernate Many to Many Relations Set Or List?

Question

I have a many to many relationship at my Java beans. When I use List to define my variables as like:

@Entity
@Table(name=\"ScD\")
public class G         


        

Answer 1

How about the uniqueness requirement from Set? Doesn't this force Hibernate to retrieve all objects each time one is added to the collection to make sure a newly added one is unique? A List wouldn't have this limitation.
