[GitHub] [spark] cloud-fan commented on pull request #35669: [SPARK-38041][SQL]DataFilter pushed down with PartitionFilter

   This looks like an interesting optimization. For file sources, the pushed predicate can be dynamic: we can fill the value of the partition columns in the pushed predicate, when pushing down the predicate to Parquet at the task runtime.
