[jira] [Created] (SPARK-32842) Support dynamic partition pruning hint

Yuming Wang created SPARK-32842:
-----------------------------------

             Summary: Support dynamic partition pruning hint
                 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


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.
