Hequn Cheng commented on FLINK-9687: ------------------------------------ Good catch. When isFire=false, there is no need to get contents from window state. > Delay the state fetch only when the triggerResult is fire > --------------------------------------------------------- > > Key: FLINK-9687 > URL: https://issues.apache.org/jira/browse/FLINK-9687 > Project: Flink > Issue Type: Improvement > Components: Streaming > Affects Versions: 1.5.0 > Reporter: aitozi > Assignee: aitozi > Priority: Major > > 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). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
