Removing entity class



I am using evaluation version of ObjectDB for long term private project. Recently I hit the 10 entities limit and got exception:

com.objectdb.o.UserException: Too many persistable types (>10) - exceeds evaluation limit

Among the 10 entities in the project there are 2 entities I added long time ago and they were never really used. I deleted them from Java source code, but there are still in ObjectDB database. The 2 tables for these entities are empty, but the tables exist, so they count into 10 entities limit.

My question is: Is it possible to remove entity/table completely from ObjectDB database, in order to make space for new entity?

Thank you in advance for any answer.

Best Regards



Unfortunately removing a class is currently unsupported.

You will have to create a new empty database and copy the content of the old database to the new one.

Ok, is there any simple way how to do it, for example with ObjectDB Explorer?


You can retrieve all your objects, detach them, and then persist them to a new database.

If the database is larger then memory it may become more difficult.
