Mongo support is almost feature complete. Jettro is working on the Mongo Saga Repository, which is the last missing piece in Mongo support.
AMQP is in an earlier stage. Spring-AMQP support was easy to build and is available. I still plan to create a non Spring-dependent AMQPCluster. That’s not as easy as creating a channel and configuring a listener on it; it must also be resilient to connection failures.
If you have time to implement it, you’re most welcome to do so. Let me know, so that I can get you started on the design concepts I have in mind.
