        This generic JobFactory function allows all splitters to easily
        retrieve the parameters to specify the resource requirements for
        the created jobs.
        # TODO: Check couchDB for performance on the current task
                and if not available it falls back to the default params.
        It returns a tuple with the following values:
        timePerEvent, sizePerEvent, memoryRequirement

    timePerEvent = defaultParams.get('timePerEvent', 0) or 0
    sizePerEvent = defaultParams.get('sizePerEvent', 0) or 0
    memory = defaultParams.get('memoryRequirement', 0) or 0
    return timePerEvent, sizePerEvent, memory
