Using ActiveMQ (successfully) for a lot of different types of messages. But that is a particular scenario for one particular type of message. Adding and installing a database on all nodes of a large system of systems of variegated nodes is not a viable option (different OS, different programming languages). As ActiveMQ is already installed (or easy to install) in all of those nodes, if there was an option to keep/consider only the most recent message on a persistent topic, then that would be an elegant solution with minimal impact on the current architecture. cheers Andrea -- View this message in context: http://activemq.2283324.n4.nabble.com/Durable-Topic-only-most-recent-message-needed-tp4666565p4666616.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
