----------------------------------
Assignee: Caizhi Weng
> Lookup joins should deal with any intermediate table scans correctly
> --------------------------------------------------------------------
>
> Key: FLINK-21478
> URL: https://issues.apache.org/jira/browse/FLINK-21478
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Affects Versions: 1.12.0, 1.13.0
> Reporter: Caizhi Weng
> Assignee: Caizhi Weng
> Priority: Major
>
> This subtask is more complex because it has to deal with temporal joins with
> a view. Currently general rules for temporal joins are not dealing with this.
> But 99.9% of users will only perform lookup joins with just the lookup table
> source. Temporal joins with views are rare and we do no need to hurry for
> this subtask.
