Motivation

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.

Rejected Alternatives
