[jira] [Created] (FLINK-9959) JoinFunction should be able to access Window


Bowen Li created FLINK-9959:
-------------------------------

             Summary: JoinFunction should be able to access Window
                 Key: FLINK-9959
                 URL: https://issues.apache.org/jira/browse/FLINK-9959
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API
    Affects Versions: 1.5.1, 1.6.0
            Reporter: Bowen Li
            Assignee: Bowen Li
             Fix For: 1.7.0


e.g. currently, a windowed join looks like this, and the JoinFunction doesn't have access to the Window it runs against.

{code:java}
A.join(B)
	.where(...)
	.equalTo(...)
	.window(...)
	.apply(new JoinFunction<IN1, IN2, OUT>() {});
{code}

We can give JoinFunction access to its Window as {{JoinFunction<IN1, IN2, OUT, Window>}}
