[Question] Multiple Kafka clusters with the same topic name and namespace

I have two Kafka clusters, Kafka-a, and Kafka-b. They are in a namespace, and the auto.create.topics.enable the option is turned on, and both use a topic (user) with the same name. When the user topic is automatically set by Kafka After creation, the topics operator will create a corresponding KafkaTopic resource in the k8s namespace to manage the corresponding topic, and then they will have the same name

Is there a way to add a prefix to the KafkaTopic created by the topicOperator in the k8s namespace, similar to

kakfa-a-user kakfa-b-user

From your description I’m not sure I understand why would each project require multiple Kafka clusters. I can see why it might be an inconvenience, but I do not think there is anything you can do about it right now.

You can also disable the topic operator by removing the topicOperator: {} section from the Kafka CR.

Just like openshift, we use the namespace of Kubernetes to distinguish projects. In most cases, there will not be multiple instances of Strimzi Kafka in a project.

BTW: spec.topicName is optional - so in many resources it will not be there.
