You likely want to remove the sourcepath here.

Better: new PersistenceFailureException("Delete operation failed", e);

Do you have any perf numbers for running this backend? Basically, I am trying to figure out the benefit it can bring to voldemort, e.g. performance improvements, or better manageability in a multi-tenant environment?

All I have is this doc that I created when I contributed the db4o implementation: http://nosql.mypopescu.com/post/1080750812/using-object-database-db4o-as-storage-provider-in
