> While JBMESSAGING-1416 states message ordering feature in a singleton configuration, customer is also requesting a complete message ordering feature which is applicable in a clustered environment.
> Here's the background:
> In the case JMS is used, both performance and scalability are priority.
> There is a conflict between scalable JMS implementation and complete message ordering feature since order aware messages cannot be processed concurrently.
> But order unaware queues should be still processed in parallel for better throughput.
> Additionally, there are some cases that no downtime is acceptable. But HA-Singleton requires certain amount of time to fail-over the service to other node.
