Hello, I would like to know if it's possible to copy the content of a table representing one class of object to another table whithout having to use java object (no object instantiation) ? In fact, I would like to execute a native query like "select * into T0 from T1" My purpose is to backup

Added Online Backup utility ( issue #16 ). Added Master-Slave  Replication / Clustering (issue #17 ). Added a PDF version of the ObjectDB manual (included in the download). Added sample (tutorials) Maven projects (included in the download). Added support of disabling optimistic locking

ObjectDB Replication will enable managing the same ObjectDB database using multiple ObjectDB nodes or servers. This could be useful for distributed applications (e.g. in cloud computing), for load balancing, for improving durability, for backup , etc. support Support Master-Slave replication

Added a new Doctor.run(srcPath, dstPath) static method. Added an option to exclude inherited @Id fields in embeddable classes. Added support for manual starting of online backup threads ( feature request #2855 ). Added support for distinct mapped-by (inverse) fields. Improved query plan
