I have a process that demands high volume - 1000 or more concurrent processes - and high latency - some async steps that require a 2-5 day wait. I realize there are countless way to address problem this outside of a BPMS, but i was wondering how Jbpm handled async nodes/actions and if resources outside of process/transactional data in persistent store are kept around during an async operation. My fear is that, for example, Threads and other resources outside of persistent store are held in a suspended state while waiting for a signal - instead of releasing all these resources and then re-allocating them when signalled. I realize there are transactional considerations in retaining thread based resources and possibly others as well, but any explanation about the resource management and scalability of the async module would be greatly appreciated.
