Soumabrata Chakraborty commented on KAFKA-5072:
-----------------------------------------------
PR created: https://github.com/apache/kafka/pull/2873
The PR has a WIP tag since I am not sure how to add this to the documentation
given that the list of kafka topic properties is auto-generated
Before the change:
[soumabrata@Krishna bin]$ ./kafka-configs.sh --zookeeper localhost:2181
--entity-type topics --entity-name demo --alter --add-config
'metadata.contact.info=soumabr...@gmail.com'
Error while executing config command Unknown Log configuration
metadata.contact.info.
org.apache.kafka.common.errors.InvalidConfigurationException: Unknown Log
configuration metadata.contact.info.
After the Change:
[soumabrata@Krishna bin]$ ./kafka-configs.sh --zookeeper localhost:2181
--entity-type topics --entity-name demo --alter --add-config
'metadata.contact.info=soumabr...@gmail.com'
Completed Updating config for entity: topic 'demo'.
[soumabrata@Krishna bin]$ ./kafka-configs.sh --zookeeper localhost:2181
--entity-type topics --entity-name demo --describe
Configs for topic 'demo' are metadata.contact.info=soumabr...@gmail.com
> Kafka topics should allow custom metadata configs within some config namespace

> URL: https://issues.apache.org/jira/browse/KAFKA-5072
> Project: Kafka
> Issue Type: Improvement
> Components: config
> Affects Versions: 0.10.2.0
> Reporter: Soumabrata Chakraborty
> Assignee: Soumabrata Chakraborty
> Priority: Minor
>
> 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.
