Paul Rogers created DRILL-5005: ---------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
