The minimum and maximum priority items will always be at the beginning and end of the queue, respectively, allowing us to efficiently peek or pop them. The ordering of keys will sort items first by priority, then by push order, then randomly (to break ties in concurrent pushes). By making keys unique, we can minimize conflicts for concurrent pushes. We can model a priority queue using a key formed from a tuple of three elements: an item’s priority, an increasing integer encoding the order in which the item was pushed, and a random element to make the key unique.
