-----------------------------------

             Summary: Parquet Complex Reader for nested schema should have configurable memory or max records to fetch
                 Key: DRILL-6853
                 URL: https://issues.apache.org/jira/browse/DRILL-6853
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Nitin Sharma


Parquet Complex reader while fetching nested schema should have configurable memory or max records to fetch and not default to 4000 records.

While scanning TB of data with wider columns, this could easily cause OOM issues.
