Damien Profeta created DRILL-5796:
-------------------------------------

             Summary: Filter pruning for multi rowgroup parquet file
                 Key: DRILL-5796
                 URL: https://issues.apache.org/jira/browse/DRILL-5796
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Parquet
            Reporter: Damien Profeta


Today, filter pruning use the file name as the partitioning key. This means you can remove a partition only if the whole file is for the same partition. With parquet, you can prune the filter if the rowgroup make a partition of your dataset as the unit of work if the rowgroup not the file.
