VerifiedDesigning for the runtime plane technology architecture

When a Mule application that uses VM queues is deployed to a customer-hosted cluster or to multiple CloudHub v1.0 workers/replicas, how are messages consumed among the nodes?

Explanation

VM queues are shared across the active nodes of a Mule cluster, and Mule can process a queued message on the originating node or on another available cluster node to distribute load. The runtime does not guarantee a sequential, round-robin, or primary-node-only consumption pattern, so node selection is non-deterministic.
