JIRA: - KAFKA-7139Getting issue details... STATUS
Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).
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"
Proposed Changes && Public Interfaces
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".
Compatibility, Deprecation, and Migration Plan
- No compatibility issue since the default value of exclude-internal is false.
