@pvillard31,
Following some of the discussion on the mailing list recently and the
original commentary on the JIRA [1], I'd like to propose shifting from an icon
based approach when back pressure is engaged to a progress bar style approach
where the user can quickly get a sense of how 'full' the queue is currently.
The mockup shows various configuration scenarios.
- Expiration (clock icon)
- Object and Data size backpressure (left and right bars respectively)
- Empty bar - backpressure not configured
- Partial bar - backpressure configured, partial represent precentage full
- Full solid bar - backpressure engaged
If you're up for some additional cycles on this PR I'd be happy to work
through the changes with you. If not, I'm happy to take what you started and
continue toward the mockup above.
Thanks!

> 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.
