----------------------------------
Assignee: Yang Xu
> Support semi/anti interval joins
> --------------------------------
>
> Key: FLINK-23305
> URL: https://issues.apache.org/jira/browse/FLINK-23305
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / Planner
> Reporter: Timo Walther
> Assignee: Yang Xu
> Priority: Major
>
> I don't see a reason why we shouldn't support interval joins also for
> semi/anti joins like:
> {code}
> SELECT *
> FROM OT
> WHERE EXISTS (
> SELECT *
> FROM TT
> WHERE TT.tx = OT.tx AND
> TT.isEnd = TRUE AND
> TT.rowtime BETWEEN OT.rowtime AND OT.rowtime + INTERVAL '1' HOUR)
> {code}
> The resulting plan contains a join operation anyway but without detecting the
> interval.
