i'm looking for scenario engine.
We have 10-20 scenarious(processes) and ~2 000 000 users. So, i made test and i see that jBPM5 stores instances of BPMN processes, wich waits for catching intermediate event, in RAM. Is any capability not to store that information in RAM but save it into database and when wait period (1-2 days) ends, restore state of instance and run it starting from waiting step?
