------------------------------------
[~LuciferYang]
> DataFilter pushed down with PartitionFilter for Orc
> ---------------------------------------------------
>
> Key: SPARK-38427
> URL: https://issues.apache.org/jira/browse/SPARK-38427
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Jackey Lee
> Priority: Major
>
> 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.
