The fanout URL is originally designed for producing into multiple brokers at once. But an enhancement to consume from multiple brokers simultaneously would be nice. Currently a 'primary' connection is selected out of all underlying transport connections, and all consumption is attached to the 'primary' connection.
This behaviour was already requested in the community: http://activemq.2283324.n4.nabble.com/Single-consumer-for-multiple-brokers-td2362045.html. But I've been unable to find any follow-ups, hence creating this ticket.
