----------------------------------
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.
