Let's say I have a table with millions of rows. Using JPA, what's the proper way to iterate over a query against that table, such that I don't have all an in-memory List with millions of objects?

I suspect that the following will blow up if the table is large:

List<Model> models = entityManager().createQuery("from Model m", Model.class).getResultList();

for (Model model : models)
{
     // do something with model    
}

Is pagination (looping and manually updating setFirstResult()/setMaxResult()) really the best solution?
