The profile counters for the partial sort don't all make sense:
We should probably indicate this is a partial sort, and consider:
- rename/remove InitialRunsCreated/SpilledRuns - we care here about the number of partial sorts, not sure how to phrase that
- check if this makes sense: SortDataSize
- remove TotalMergesPerformed
We should also address misleading info in the plan (in addition to the profile mentioned above). See Juan Yu's comment.
