Bill, The node assignment can change only when the cluster topology changes. I.e., when a new node joins the cluster or a node is removed from the cluster. Note that this does not include when a node becomes disconnected - only when it’s completely removed. At that point, if a different node is elected as the “Winner” all data will be pushed from the queue to the new node.
