             Summary: Potential issues with external sort info in query profile
                 Key: DRILL-5005
                 URL: https://issues.apache.org/jira/browse/DRILL-5005
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.9.0
            Reporter: Paul Rogers
            Priority: Minor


Run a query that will include an external sort.

Look at the visualized plan. The external sort is shown in the tree as just 
"Sort". Suggestion: say "External Sort".

In the operator profiles section, memory use for EXTERNAL_SORT is listed as 
26MB. Yet the file being sorted is 388 MB. Even allowing for projects of a 
subset of column, 26 MB seems awfully small to hold the data set.
