["Taiyuan Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-3649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15270149#comment-15270149 ] 

Taiyuan Zhang commented on KAFKA-3649:
--------------------------------------

When you're talking about configuration settings, are you referring to the settings in server.properties, the property config file when starting the broker?

What are the use cases, that make you want to query/update those configurations at run-time?

> Developing an API by which running brokers could be queries for the various configuration settings is an important feature to managing the Kafka cluster.
> Long term, the API could be enhanced to allow updates for those properties that could be changed at run time ... but this involves a more thorough evaluation of configuration properties (which once can be modified in a running broker and which require a restart {of individual nodes or the entire cluster}).
