> 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: Task
> Components: Documentation, Table SQL / API
> Reporter: Jark Wu
> Assignee: Jark Wu
> Priority: Blocker
> Fix For: 1.11.0
>
>
> 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.
