    If the @Producer method of the underlying Emitter can return null before the data are completely read - i.e. infinite flow case - then you should set true to prevent the execution to complete when null is encountered. Default cases matches a batch case whereas when set to true it matches a stream case.
    
    Returns:
    
    true if the underlying input can be used as a stream and not in batch context.
    
    Default:
    
    false
