Techniques are provided for dynamically re-ordering operation requests that have previously been submitted to a queue management unit. After the queue management unit has placed multiple requests in a queue to be executed in an order that is based on priorities that were assigned to the operations, the entity that requested the operations (the "requester") sends one or more priority-change messages. The one or more priority-change messages include requests to perform operations that have already been queued. For at least one of the operations, the priority assigned to the operation in the subsequent request is different from the priority that was assigned to the same operation when that operation was initially queued for execution. Based on the change in priority, the operation whose priority has change is placed at a different location in the queue, relative to the other operations in the queue that were requested by the same requester.
