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(). #1 2014-08-06 16:06 This is not a rellay ObjectDB problem, rather a JPA problem.

mappedBy problem

If I put the mappedBy element to the @OneToMany, the owned side (the many side) will never persist ! for example @Entity public class Employee { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) public Long id; public String name; @OneToMany(targetEntity=Address.class,mappedBy="employee") public List<Address> addresses; }   @Entity... is set (because the mapped by side is merely a request to execute a query). You are right about the Explorer. Currently inverse ...

Use temporary files to enable very large transactions

We have transactions in which many objects are created. These objects are no longer needed in the current transaction after creation. Unfortunately, we will receive an OutOfMemory exception because the objects are kept in the first level cache of ObjectDB. In the forum thread http://www.objectdb.com/database/forum/921 on post #4 you wrote, that ObjectDB should support very large transactions in further version. Can you implement it that ObjectDB used temporary files? Bug Version: 1.04 Priority: Critical Status: Fixed Replies: 27 Type:  Bug ...
