Dan Bress commented on NIFI-766:
--------------------------------
Mark,
I this is a great idea. What if the background of a connection label was
filled (left->right) indicating how close it is to applying back pressure?
e.g.
Lets say Back pressure object threshold is set to 10 for a connection, and
there were 3 objects in it
then the left 3/10ths of the label could be shaded gray
if there were 6 objects
the left 6/10ths of the label could be shaded gray
if there are 10 objects or more
the whole label could be shaded a gray(or another color) or maybe have a
warning/bulletin label attached to it indicating that back pressure happened.
This might be better illustrated with pictures... If what I am describing isn't
clear i'll try and gen up some PNGs
> UI should indicate when backpressure is configured for a Connection

> It is sometimes unclear why a Processor is not running, if it is due to
> backpressure. Recommend we add an icon to the Connection label to indicate
> that backpressure is configured. If backpressure is "applied" (i.e., the
> backpressure threshold has been reached), that icon should be highlighted
> somehow.
