Subject [jira] [Created] (FLINK-8510) Provide access to Delivery envelope in RabbitMQ Source

---------------------------------------

             Summary: Provide access to Delivery envelope in RabbitMQ Source
                 Key: FLINK-8510
                 URL: https://issues.apache.org/jira/browse/FLINK-8510
             Project: Flink
          Issue Type: Wish
            Reporter: Wojciech Luczkow


Currently RMQSource is limited to get AMQP message body in resulting Stream,

sometimes it would be good to get access to Envelope

 

For example 

if subscribing to Topic using Routing Key amq.topic.#

it is impossible to distinguish whether message came from amq.topic.1 or amq.topic.2

 

Studying current implementation I think the easiest option from consumer point of view would
be to change RMQSource<OUT>  to provide Stream<RMQMessage<OUT>> which will
break Flink API...

Another would be to create something like detailedsource with different API - provide generic
Wrapper with message content <OUT> and Map with message properties (and protected method
to override and fill that map).
