> 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.
