Kurt Deschler commented on IMPALA-11970:
----------------------------------------
Q21 Example showing DAG connections on the right that were necessary to
properly render complex plans. Previous examples showed multiple edges into
exchanges which was incorrect.

Same example with plan-order printing:

> Query profiles contain timing information for fragments and plan nodes that
> is difficult to analyze in a text format, especially for complex and
> highly-parallel execution plans. A graphical display in the WebUI that
> renders timing information in Gantt chart form will make the execution timing
> and dependencies much easier to follow.
