> Currently, in the docuementation, we call the joins with time conditions as "Time-windowed Join". However, it is called "Interval Join" in DataStream. We should align the terminology in Flink project. 
> From my point of view, "Interval Join" is more suitable, because it joins a time interval range of right stream[1]. And "Windowed Join" should be joins data in the same window, this is also described in DataStream API. 
> For Table API & SQL, the "Time-windowed Join" is the "Interval Join" in DataStream. And we miss the new feature "Windowed Join" in Table API & SQL.
> I propose to correct the terminology in docs before 1.10 is release.
