[jira] [Commented] (KAFKA-5072) Kafka topics should allow custom metadata configs within some config namespace

["Florian Albrecht (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-5072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17476089#comment-17476089 ] 

Florian Albrecht commented on KAFKA-5072:
-----------------------------------------

Really would like to see this implemented (especially because the PR is quite trivial). We could also use additional meta information assigned to each topic - currently, we have an extra topic where we store metadata information for each topic.

Imagine all the possibilities - e.g. could CLI tools filter for topics based on this metadata fields when listing topics ("give me all topics belonging to development team A").

> Kafka topics should allow custom metadata configs
> Such config properties may have some fixed namespace e.g. metadata* or custom*
> This is handy for governance.  For example, in large organizations sharing a kafka cluster - it might be helpful to be able to configure properties like metadata.contact.info, metadata.project, metadata.description on a topic.
