How to List Internal Topics in ksqlDB

Internal topics are generally topics created by Kafka Streams applications to store metadata about the jobs. They can also be created by Kafka brokers to track various information such as consumer group offsets. The LIST command hides internal topics by default and only prints user topics.

If you also want to list those internal topics, you can use the ALL modifier:

LIST ALL TOPICS;

Don’t forget that you can also write SHOW instead of LIST. In ksqlDB, those two commands are synonyms.
