---------------------------------
Summary: Return metadata of sensitive config when describe config
Key: KAFKA-18005
URL: https://issues.apache.org/jira/browse/KAFKA-18005
Project: Kafka
Issue Type: Improvement
Reporter: Luke Chen
Assignee: Luke Chen
Currently, when describing config for a resource, we'll get `null` if the
config is a sensitive config, ex: "ssl.keystore.certificate.chain",
"ssl.keystore.password". And when describing configs with them it'll always
return something like this:
{code:java}
> bin/kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers
> --entity-name 2 --describe
Dynamic configs for broker 2 are:
listener.name.plantext.ssl.keystore.key=null sensitive=true
synonyms={DYNAMIC_BROKER_CONFIG:listener.name.plantext.ssl.keystore.key=null}
{code}
It would be great if the broker can return some metadata of these sensitive
configs, like last modified timestamp, to allow readers (ex: the operator) to
know if this is an outdated value.
