> Optimize the dynamic partitioning prune rules to avoid inserting unnecessary
> predicates to improve performance
> --------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-37542
> URL: https://issues.apache.org/jira/browse/SPARK-37542
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0, 3.0.1, 3.0.2, 3.0.3, 3.1.0, 3.1.1, 3.1.2, 3.2.0
> Reporter: weixiuli
> Priority: Major
>
> Currently, the dynamic partition pruning rule will insert a predicate on the
> filterable table using the filter from the other side of the join and a
> custom wrapper called DynamicPruning，and the predicate will be re-optimized
> by the AQE or non-AQE.
> But, sometimes the predicate may be unnecessary if the join can NOT reuse
> broadcastExchange or it is not benefit，and it will be dropped by the rules of
> the AQE or non-AQE.
> We should optimize the dynamic partitioning pruning rule to avoid inserting
> unnecessary predicates to improve performance.
