Paul Rogers resolved DRILL-5005. -------------------------------- Resolution: Fixed Fix Version/s: 1.10.0 The label in the tree is left at "Sort" because, in modern Drill, all sorts use the external sort. The older non-spillable sort is no longer used. Memory usages for the sort were vastly revised, which should address the memory concern in this issue. > 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 > Assignee: Paul Rogers > Priority: Minor > Fix For: 1.10.0 > > > 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 (v6.3.15#6346)
