Caching Layer

Definitions

1. A layer in the architecture dedicated to storing and serving cached data between producers and consumers. A caching layer often sits between the application and a slower dependency like a database or remote API, reducing repeated expensive calls.

   In plain English: A dedicated layer in the system that handles caching.

   Example: "The service added a caching layer in front of the catalog database so repeated reads during sales events stopped saturating primary storage."
