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

             Summary: Improve parquet reader performance
                 Key: DRILL-4800
                 URL: https://issues.apache.org/jira/browse/DRILL-4800
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Parth Chandra


Reported by a user in the field - 

We're generally getting read speeds of about 100-150 MB/s/node on PARQUET scan operator. This
seems a little low given the number of drives on the node - 24. We're looking for options
we can improve the performance of this operator as most of our queries are I/O bound.
