[jira] [Created] (DRILL-6814) Query performance on S3 files

Ashish Shukla created DRILL-6814:
------------------------------------

             Summary: Query performance on S3 files
                 Key: DRILL-6814
                 URL: https://issues.apache.org/jira/browse/DRILL-6814
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Other
    Affects Versions: 1.14.0
         Environment: Amazon EC2 instances-
4 Linux Redhat machines -version 7.5
RAM- 32GB
            Reporter: Ashish Shukla


I have installed 4 Node drill cluster on Amazon EC2 and  trying to execute a simple count on one Amazon S3 file. File type is CSV and size is approx- 14GB.
 The query returns expected count after the execution of approx 30 minutes.
 If we keep the same file in hdfs or create a table in postgres, execution time is relatively very less (approx 2-3 minutes).
 Is it normal behavior or something can be done for S3 files to make execution time comparable.
