             Summary: Correct the terminology of "Time-windowed Join" to "Interval Join" in Table API & SQL
                 Key: FLINK-15339
                 URL: https://issues.apache.org/jira/browse/FLINK-15339
             Project: Flink
          Issue Type: Sub-task
          Components: Documentation
            Reporter: Jark Wu
             Fix For: 1.10.0


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.
