Updating existing persistence entries

I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them to a kind of property editor in my app (it simply calls the setters to reflect gui editing actions). When I try to persist a object later on, I get an error like com.objectdb.o.UserException: Attempt to reuse an existing primary key value which makes sense to me but I'm missing a em.update() method. #1 2012-12-07 19:29 I have stored some instances of MyObject via em.persist(myObjectInstance); I can fetch them and bind them ...

Incremental online backup

Hello, Are there plans for ObjectDB to handle incremental online backups, where a backup does not create a whole new copy of the DB, but "updates" an existing backup? This behavior would make backups much faster as only a portion of the data would need to be copied. Such a feature would also allow to perform backups more often, several times a day, in order to always have a backup that's closer to the current state of the DB. Thank you #1 2016-04-07 10:19 Hello, Are there plans for ObjectDB to handle incremental online backups, where a backup does not create ...
