Lars Volker created IMPALA-5185:
-----------------------------------

             Summary: Parquet scanner should skip pages based on parquet page statistics
                 Key: IMPALA-5185
                 URL: https://issues.apache.org/jira/browse/IMPALA-5185
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Lars Volker
            Assignee: Lars Volker


IMPALA-2328 added support to skip row groups based on row group statistics. We also need to support skipping pages based on page statistics. As a prerequisite the parquet scanners need to be adapted to support synchronous row skipping.
