[rules-users] Drools Flow persistance

Hello, I been searching through all the documentation I could find about how to persist a flow. In the whats-new-in-drools-5-video-and-q session I found the following: ---------------------------- Q: For long-running processes involving human tasks, how is the state of the process/flow persisted? A: Various approaches available - database via hibernate for instance, file system, all intended for high performance. Working Memories are now transactional and persistable (JPA is also an option). ---------------------------- Is there any examples available somewhere which describes how to persist to the file system (for a simple start)?
