[jira] [Updated] (DRILL-6814) Query performance on S3 files
[ https://issues.apache.org/jira/browse/DRILL-6814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ashish Shukla updated DRILL-6814:
---------------------------------
Description:
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 ?
