Summary

Cache stampede occurs when a popular cache item expires, leading to multiple requests regenerating the item at the same time, causing performance issues. To mitigate this, approaches include external re-computation, locking, and probabilistic early expiration, where each request makes an independent probabilistic decision to regenerate the item before its expiration. This paper presents an optimal algorithm for probabilistic early expiration using an exponential function, which is simple, effective, and requires no parameter tuning.
