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>}}
