[rabbitmq-discuss] Recommended queue architecture

Thu Dec 19 11:34:14 GMT 2013

Hi,

RabbitMQ won't do any aggregation for you. What you could do is route
similar messages to the same queue(s). Also AMQP messages can have a
correlation_id property that you could use to aggregate them later.

Regards,

Alvaro
