JPA and handling large data sets

This is not a rellay ObjectDB problem, rather a JPA problem. Our web-based DB supports Hibernate or JPA (ElicpseLink/ObjectDB). We implemented a export/import class to export the whole database or single datasets (domains) in a persistence layer/database independent format. This class works fine - DB exports form a Hibernate/MySQL base via the independent formt to ObjectDB is possible. But exporting large binary data sets is very slow. To avoid memory problems the binary data type is read step by step during the export with the  query/setFirstResult() & setMaxResults()....
