JPA: what is the proper pattern for iterating over large result sets?

Question

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-memo

Answer 1

You can't really do this in straight JPA, however Hibernate has support for stateless sessions and scrollable result sets.

We routinely process billions of rows with its help.

Here is a link to documentation: http://docs.jboss.org/hibernate/core/3.3/reference/en/html/batch.html#batch-statelesssession
