I guess you could call it a persistence service of sorts, although the persistence is done outside of the JBPM realm. Yes, I do lose a bunch of functionality such as timers etc.. Those types of things would need to be built into my own application if I needed them. The standard jBPM persistence model worked great for me as a proof-of-concept....I just had problems when I tried to ramp up the throughput, and that is what forced me to use this model.
