There will not be a DLQ/RDQ in the same fashion as currently exists in ESB4. The redelivery mechanism will be an integral part of the bus along with its integration to other ESB instances.

So yes, it could still use the JBM log, but it definitely wouldn't be shared by JBossTS for a start and you wouldn't see much performance benefit since the bottleneck will be the network. My previous posting was not commenting on any integration with JBossTS as any potential integration would exist be at a lower level than we are currently dealing with. We are more concerned with an internal bus structure for the new architecture. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192094#...
