But if you want a Kafka cluster which serves multiple namespaces then Kafka topic is not namespaced resource. That means a lot of complications. For example what should we do when the same topic is configured within different namespaces? So I do not think we can see the presence of the config map for given topic in the namespace as a proof of ownership for the topic.<o:p></o:p></p> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal">I think that the general idea is quite good.
