Kafka AdminClient listTopics: is there a way to ignore kstreams topics?

Question

I'm doing the following:

    var listTopicOptions = ListTopicsOptions().listInternal(false)
    var topicsInKafka = adminClient().listTopics(listTopicOptions).names().get()

But I'm still getting topic names likes xxx-kstreams-yyyy-changelog or xxx.internal.self.yyy

No, you can't avoid those topic names by setting listInternal(false) . As mentioned, it will exclude kafka _consumer_offsets and _transaction_state topics.

If you don't want to see the kafka stream application generated changelog/repartition topics, you can define a regex in your code which can exclude all the topics matching and give you only user topics.
