David Oftedal commented on CAMEL-16438:
---------------------------------------
Example project: [^kafka-chaos.zip]
Note that there are two properties in ApplicationTest.java that have to mirror
the names used in the YML files, as the unit tests and the embedded Kafka
broker need to know the broker URL and topic name.
The code is run on Java 11.
> Kafka component properties randomly end up under camel.component.kafka or
> camel.component.kafka.configuration

> Key: CAMEL-16438
> URL: https://issues.apache.org/jira/browse/CAMEL-16438
> Project: Camel
> Issue Type: Bug
> Components: camel-kafka
> Affects Versions: 3.8.0, 3.9.0
> Reporter: David Oftedal
> Priority: Minor
> Attachments: kafka-chaos.zip
>
>
> According to
> [https://camel.apache.org/manual/latest/camel-3x-upgrade-guide-3_2.html#_configuring_components_via_spring_boot_auto_configuration]
> , Camel component configuration should as of version 3.2 no longer use the
> .configuration prefix.
> In version 3.8.0, many properties have indeed moved out of .configuration.
> But some properties are still only set if set with the .configuration prefix.
> The same seems to be the case in 3.9.0 as well.
> As far as I can tell, this non-exhaustive list contains valid examples:
> * camel.component.kafka.configuration.brokers (specifically mentioned in the
> documentation as having moved)
> * camel.component.kafka.configuration.max-poll-records
> * camel.component.kafka.configuration.group-id
> * camel.component.kafka.configuration.topic
> * camel.component.kafka.configuration.ssl-keystore-password
> * camel.component.kafka.configuration.ssl-truststore-password
> * camel.component.kafka.configuration.value-deserializer
> Some properties seem to have moved *to* .configuration:
> * camel.component.kafka.configuration.allow-manual-commit
> * camel.component.kafka.configuration.break-on-first-error
> Some related properties now appear to be split between two prefixes:
> * camel.component.kafka.ssl-keystore-location and
> camel.component.kafka.configuration.ssl-keystore-password
> * camel.component.kafka.ssl-truststore-location and
> camel.component.kafka.configuration.ssl-truststore-password
> * camel.component.kafka.value-serializer and
> camel.component.kafka.configuration.value-deserializer
> Trying to figure out what goes where requires a pretty exhaustive and
> error-prone search.
> Obviously it's possible to copy and paste each property so that it's set
> both with and without .configuration, but if the intent is to remove
> .configuration altogether, would it be possible to either confirm or negate
> what we're seeing?
