-----------------------------
Description:
The example of {{CoGroupedStream}}
{code}
DataStream<T> result = one.coGroup(two)
.where(new MyFirstKeySelector())
.equalTo(new MyFirstKeySelector())
.window(TumblingEventTimeWindows.of(Time.of(5, TimeUnit.SECONDS)))
.apply(new MyCoGroupFunction());
{code}
the params of method {{equalTo}} should be {{MySecondKeySelector}} instead of
{{MyFirstKeySelector}}.
