Not all traffic is created equal. When a database is overwhelmed, you want the important queries to keep executing, even if that means shedding lower-priority work. This is a much better outcome than the alternative: a total database outage.
PlanetScale’s Traffic Control makes this feasible at the database level by introducing resource budgets. These let you apply strict limits on slices of traffic, protecting resources for high-priority queries even when there’s a surge in requests. <a href="https://planetscale.com/blog/graceful-degradation-in-postgres" target="_blank" rel="noopener nofollow">Read our blog to learn more</a>.
