[QUESTION] Are broadcasts mandatory?

Hey @dashersw! Thanks for a great project.

I have an issue with `Publisher`s.
I'm using `redis` to make `cote` works in `Kubernetes`.

Everything works perfect until in hours my events published with `Publisher` start to get lost. I have no errors or so but just a quiet after event publish. Nothing helps but just a restart `redis` pod or publisher/responder pods. Then it will work again for a few hours...

I'm not really clear with `broadcasts` parameter for `Publisher`. Are it is mandatory? May I have these problems because I did not specified `broadcasts`?

Thanks you so much!

The report names Publisher, broadcasts, Redis, and Kubernetes but no repository files or tests. Start by locating the Publisher broadcast configuration and investigating the event loss over time; done means determining whether broadcasts are required and documenting a confirmed cause or diagnostic next step.
