I believe you want the following flag:

I believe our documentation recommends storing the PersistenceManagerFactory
as a singleton, but using a new PersistenceManager each time (remembering to
close it before discarding).

memory (and simply flushes to disk periodically), so you will run into size
issues at some point.
