> At present, for orc data source, the Filter is divided into DataFilter and PartitionFilter when it is pushed down, but when the Filter removes the PartitionFilter, it means that all Partitions will scan all DataFilter conditions, which may cause full data scan.
> Based on SPARK-38041, we can pushdown dataFilter with partitionFilter to ORC, and remove partitionFilter at runtime.
