Yuming Wang updated SPARK-27714:
--------------------------------
    Target Version/s:   (was: 3.0.0)

> Support Join Reorder based on Genetic Algorithm when the # of joined tables > 
> 12
> --------------------------------------------------------------------------------
>
>                 Key: SPARK-27714
>                 URL: https://issues.apache.org/jira/browse/SPARK-27714
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.1.0
>            Reporter: Xianyin Xin
>            Assignee: Xianyin Xin
>            Priority: Major
>
> Now the join reorder logic is based on dynamic planning which can find the 
> most optimized plan theoretically, but the searching cost grows rapidly with 
> the # of joined tables grows. It would be better to introduce Genetic 
> algorithm (GA) to overcome this problem.
