-------------------------------------

[~paul-rogers] Where can we get the PR for this fix? Is it primarily a UI specific patch?

> 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.
