[GitHub] [spark] viirya commented on pull request #33639: [SPARK-36645][SQL] Aggregate (Min/Max/Count) push down for Parquet

   > If the aggregate column is on partition column, only Count will be pushed, Min or Max will not be pushed down because Parquet doesn't return max/min for partition column.
   
   So Parquet will return count for partition column?
