This month a staff software engineer at Reddit shared a real-world example of how microservices have helped improve Reddit’s resilience — a thoughtful case study drawn from his own experience of handling sudden spikes in search requests. But it’s also an example of how a long-standing problem can find new solutions in the world of microservices. And best of all, he illustrated it all perfectly with a funny metaphor from the Three Stooges.

In fact, Shah has also heard the phenomenon referred to as a “cache stampede” (as well as “the Dogpile Effect”).

Shah wrote that the reduction on load has been dramatic — especially in an environment handling tens of thousands of requests.
