Kishore Jaladi [https://community.jboss.org/people/kishorejaladi] created the discussion "A few jbpm5 architectural/design questions" To view the discussion, visit: https://community.jboss.org/message/732732#732732 -------------------------------------------------------------- I am evaluating using JBPM5 for our work flows in e-commerce context. I did some reading online. Still got a few questions. Please help * We use MongoDB as our database. I understand that JBPM5 supports JPA persistence. Is it safe to assume that with any ORM provider like Dataneucleaus that provides a JPA layer for MongoDB can used for Work Flow Engine persistence? ref: http://sasajovancic.blogspot.com/2011/06/use-jpa-with-mongodb-and-datanuc... http://sasajovancic.blogspot.com/2011/06/use-jpa-with-mongodb-and-datanuc... * Is it possible to do on-demand process-instance or ksession persistence? If so, is there any sample code? * I read that the work flow engine uses the single thread (the thread that starts the process/fires an event) to execute the entire process...no real multi-threading. What happens when the process instance and/or session is persisted at safe-points (or manually)?..does the thread end/return back to main program? * If I have to start multiple (many) processes at the same time from the main program, do I have to start them all in different threads? do I have to model my own thread pool? * I have a situation where, the main program receives a message on http and the http response thread have to be returned with status 200 OK after persisting the message. If I want the message persistence as a part of the process, how can I achieve this? I mean, I cannot return the main thread just after the first (persistence) node of the process, right?...how can make the rest of the process continue?
