> URL: https://issues.apache.org/jira/browse/DRILL-6279
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.13.0
> Reporter: Kunal Khatua
> Assignee: Kunal Khatua
> Priority: Major
> Fix For: 1.14.0
>
> Attachments: spillToDiskSnapshot.png
>
>
> Currently, there is no indication of when an operator is spilling to disk,
> which would help explain a slow running query.
> Suggestions are welcome, but the current proposal is to simply update the
> Operators Overview section to show average and max spill cycles, preferrably,
> with a color code (or formatting).
