---------------------------------------
Summary: Extend Camel RabbitMQ with guaranteed delivery
(basic.return)
Key: CAMEL-10239
URL: https://issues.apache.org/jira/browse/CAMEL-10239
Project: Camel
Issue Type: New Feature
Components: camel-rabbitmq
Affects Versions: 2.17.2
Reporter: Florian Gessner
So far camel-rabbitmq supports publisher acknowledgements to ensure that a
massage was delivered to the brokers. However this does not guarantee that the
message is delivered to queue (https://www.rabbitmq.com/confirms.html - 'When
will messages be confirmed?').
To implement guaranteed delivery publisher acknowledgements have to be
activated together with a *return listener* and publishing messages as
mandatory.
In this case the basic.return will be returned to the publisher before the
basic.nack or basic.ack. Only in this case we can be sure that the message is
really delivered to the configured queue (or fails if no queue is available).
As a solution I provided a pull request on github together with integration
tests.
