MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Nabble-From: b.terwijn@uva.nl X-Virus-Checked: Checked by ClamAV on apache.org Hello, I want to build a 'highly available' system and am now wandering why a message is owned by a single broker in a "Store and Forward Network of Brokers", as when a broker dies the messages it owns will be lost (until broker restart when using persistence)? This seems a strange choice, why have ownership of a message anyway? Alternatively brokers could forward messages to other interested brokers in the network in parallel without any broker owning the message. This way messages are never lost when a single broker dies, and messages are delivered more quickly. Can anyone shed some light on why a message is owned by a single broker at any point in time?
