The performance of your cache is defined in terms of its hit rate. The hit rate is the
percentage of the time that your cache contains the data for a user request. Ulti‐
mately, the hit rate determines the overall capacity of your distributed system and
affects the overall capacity and performance of your system.

Sometimes, you have a cold cache for static content that needs to be warmed up, especially if fetching the uncached content initiates a resource-intensive process. If simultaneous requests reach your server while the cache is cold, it can lead to executing…
This situation called cache stampede.
A cache stampede is a type of cascading failure that can occur when massively parallel computing systems with caching mechanisms come under a very high load. This behaviour is sometimes also called dog-piling.
