> When the window operator is fired by the event timer or processing timer, it 
> fetch the state content first. I think it only need to fetch the content from 
> windowState when the triggerResult is Fire. So we have to change the order to 
> avoid this cost ( the cost of fetch content from state is more than judge the 
> triggerResult).
