Usually we have no interest in internal topics when using the kafka-topics.sh command . However, the kafka-topics.sh can't exclude the internal topics simply. We have to write the regular to exclude the internal topics. This kip tries to add a flag "exclude-internal" to kafka-topics.sh. If user set the flag, all internal topics will be excluded by the following commands - "list" and "describe"
KIP-338 plan to add a new option to kafka-topics.sh to enable/disable kafka-topics.sh to show the information of internal topics. The new option is called as "exclude-internal". Assume we have a internal topic "__consumer_offsets" and a user topic "testTopic".
The following command will show both topics.
$ kafka-topics.sh --zookeeper localhost:2181 --list
The following command will show the "testTopic" only.
$ kafka-topics.sh --zookeeper localhost:2181 --list --exclude-internal
The explanation of "exclude-internal" is "exclude internal topics when running list or describe command".
