    Large Jbpm Variables Slow System Down

    David Roberts Apprentice

      Hi,

      My workflow system has the ability to attach a file. This file is streamed into a byte[], and then set as a variable on a task instance.
      Lets say I attach a file of about 2MB (or more), the system is quite slow when calling taskInstance.getVariablesLocally(), which returns a Map of variables. This must be due to the fact that the fairly large byte[] needs to be loaded. Does anyone know of a way to speed this up? Perhaps somehow not loading byte[] variables, or variables over a certain size. Then somehow only retrieve those large variable when it is actually required. I need to be aware that they exist though, which is why im using taskInstance.getVariablesLocally(), so I have the map of all available variables.
