-------------------------------
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.
