What do you suggest? The problem I see is that there's no SLA associated with delivering topic
updates, and delivery is pretty variable (initial updates of the full catalog tend to run
slower). So it's not clear what threshold to warn on, and even if action should be taken if
it's just a period of heavy load. 

I think what might be better is to keep a measure of topic update delays like a histogram
so that we can see how topic updates are doing at any time. What do you think?
