I'm currently using ActiveMQ in peer mode with brokers embedded in a number of distributed nodes. I'd like to make messages published on some topics durable, so that they are reliably delivered to subscribers. I am happy with messaging potentially being lost in the case of a restart of the publishing process in this scenario, so I don't want to make the publishers persistent.
My question is then: If I make subscribers to these topics durable (and set a suitable message expiry time), will messages be delivered in the following scenario? - I have processes P1 and P2 with embedded brokers, these are connected using the peer transport. - I have a publisher Pub1 in process P1, and a durable subscriber Sub1 in process P2, and these are communicating successfully. - The connection goes down between P1 and P2, say due to a network fault. - Pub1 publishes a message M. - The connection is restored between brokers in P1 and P2. At this point, will the message M be redelivered to Sub1? I guess my question then is: is the transport between peer brokers "durable" in the sense that durable subscriptions will be treated as such? Many thanks, Jan
