Using load shedding to avoid overload
The article does mention prioritization, but doesn't mention my favorite pattern with this.  A priority queue that favors end users "farther down the process" is nice for load shedding.<p>Like, for an ecommerce site, being able to prioritize users in the checkout path first, not-in-checkout but non-empty cart second, etc.<p>Or prioritizing features in a similar way.  Turning off, for example, "people that bought this, bought that", under load.
