----------------------------------------
Hi [~chia7712] , could you assign this ticket to me?
> Inconsistent config values in CreateTopicsResult and DescribeConfigsResult
> --------------------------------------------------------------------------
>
> Key: KAFKA-16211
> URL: https://issues.apache.org/jira/browse/KAFKA-16211
> Project: Kafka
> Issue Type: Bug
> Components: controller
> Reporter: Gantigmaa Selenge
> Priority: Minor
>
> When creating a topic in KRaft cluster, a config value returned in
> CreateTopicsResult is different than what you get from describe topic
> configs, if the config was set in broker.properties or controller.properties
> or in both but with different values.
>
> For example, start a broker with `segment.bytes` set to 573741824 in the
> properties file and then create a topic, the CreateTopicsResult contains:
> ConfigEntry(name=segment.bytes, value=1073741824, source=DEFAULT_CONFIG,
> isSensitive=false, isReadOnly=false, synonyms=[], type=INT,
> documentation=null)
> because the controller was started without setting this config.
> However when you describe configurations for the same topic, the config value
> set by the broker is returned:
> Create topic configsConfigEntry(name=segment.bytes, value=573741824,
> source=STATIC_BROKER_CONFIG, isSensitive=false, isReadOnly=false,
> synonyms=[], type=null, documentation=null)
>
> Vice versa, if the controller is started with this config set to a different
> value, the create topic request returns the value set by the controller and
> then when you describe the config for the same topic, you get the value set
> by the broker. This makes it confusing to understand which value being is
> used.
