I'd like to avoid creating messages for a topic is the topic currently has no consumers. Is there a way a producer can subscribe to the number of consumers of a topic? Or if that's not possible, can a producer request the current number of consumers of a topic?
The searchable hadoop kafka topic didn't return anything for "no consumer" or "zero consumers", and a find on "zero" or "count" on the documentation html page found lots of matches, but none about knowing the number of consumers. I'm certain I can code a solution around this problem, but I'd hate to reinvent the wheel for such a straightforward problem. Todd Gatts
