    @Aitozi Is it ok for you that I merge it but rename to FLINK-5363 and write in the commit
message that it also resolves FLINK-9687?
    I also assigned you to both of these issues.

> 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).
