Ebean ORM uses "query joins". (http://www.avaje.org) This means that the SQL query can still have the SQL limit/offset, rownum etc limiting... and an additional sql query performs the 'query join' fetch of the OneToMany or ManyToMany. This means you still get the potentially large performance benefits of the sql limit/offset etc rather than using in-memory filtering. Cheers, Rob.
