How to delete internal topic

[kaykhan]

When we create the connector msk, we need to delete the old internal topics.

But currently kafka-ui show the button grayed out, we can delete these topics manually via the kafka-topics but how do we delete them using the kafka ui.

Hi, you can't delete them because they're internal. However, you can modify the internal prefix to an empty string to make it work. Change kafka_internalTopicPrefix.

Okay, is it possible to give a specific user the permission to perform this action? I dont want all users to be able to perform this.

@kaykhan yes, with RBAC:

        - resource: topic
          value: "_.*"
          actions: delete
