Is it possible to know the number of producers for a topic?

[Dylan Martin <dm...@istreamplanet.com>]

I have a situation where I should always have exactly one producer per topic, but under certain rare circumstances I can have more than one, and that's really bad when it happens, so I want to detect it.

Can I know how many producer a topic has?  Can I identify them?

Thanks!

Not sure what yo ur exact use case is? Exactly once processing? 
Can you describe the full pipeline ?
For what you have described you could use a producer id together with the message. However , your description opens new questions - what do you plan to do in case this happens? Depending on that other solutions could make sense
