-----------------------------------
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.
