Hi everyone, Currently, in the Table API & SQL documentation[1], we call the joins with time conditions as "Time-windowed Join". However, the same feature is called "Interval Join" in DataStream[2]. 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. And "Windowed Join" should be joining data in the same window, this is also described in DataStream API[3]. For Table API & SQL, the "Time-windowed Join" is the "Interval Join" in DataStream. And the "Windowed Join" feature is missed in Table API & SQL. I would propose to correct the terminology in docs before 1.10 is release. What do you think?
