>                 Key: SPARK-32842
>                 URL: https://issues.apache.org/jira/browse/SPARK-32842
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.1.0
>            Reporter: Yuming Wang
>            Priority: Major
>
> For some joins, one side is very small but can not broadcast, for example:
>  * left join but left side very small
>  * right join but the right side very small
> At this time, {{PlanDynamicPruningFilters}} may not insert dynamic partition pruning. I'd like to add a hint to support users to force insert a dynamic partition pruning.
