Hi Kafka experts, I wrote a small utility application to terminate (delete) unused topics in our clusters. The application is hosted at https://github.com/statnett/k3a-topic-terminator (but this is not an attempt to promote the app; it's fresh ;-). We just got rid of 2816 topics in one of our clusters, and now we want to find even more garbage.
So my question is: *Can the topic creation timestamp be obtained through a Kafka Admin Client (or Client)?* I think the answer is NO, but would it be possible to implement such a feature? As a user, I would expect to find this information through the TopicDescription <https://kafka.apache.org/38/javadoc/org/apache/kafka/clients/admin/TopicDescription.html> class.As far as I understand, this information is available in the cluster - either within Zookeepers and/or on the __cluster_metadata topic. I have tried to set up a consumer towards the metadata topic, but no luck so far. I am very interested in potential workarounds until this feature is eventually implemented! In my case, this *must* be done external to the brokers/controllers/zookeepers. Running a shell script or CLI tool is not a feasible option (in this case). Regards. Erik
