[jira] [Commented] (NIFI-4303) RabbitMQConsumer: Publish the message routing key as an attribute to flowfile

["Mathieu Fortin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-4303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16797434#comment-16797434 ] 

Mathieu Fortin commented on NIFI-4303:
--------------------------------------

It seems nothing has been done on this, which I find surprising since having access to the message provenance looks like a required item for any topic-based amqp consumer. 

Any pointers on how this should be implemented ? Maybe im wrong but I think the refered code misses the underlying envelope reference, which would be required to have the routing key. I could put some time to produce a PR.

> When retrieving messages from a queue that is bound to a topic exchange, message come with a routing key which might contain crucial identifying information about where the message came from.
> Current implementation of the RabbitMQConsumer processor doesn't publish this property of the message to the attributes of the flowfile it creates. Can this be added?
> I found the relevant code here: https://github.com/apache/nifi/blob/d838f61291d2582592754a37314911b701c6891b/nifi-nar-bundles/nifi-amqp-bundle/nifi-amqp-processors/src/main/java/org/apache/nifi/amqp/processors/AMQPUtils.java#L95
> I have very sketchy Java skills, otherwise would submit a PR.
