TieredCache<T> class
Tiered implementation of the Cache interface allowing the assignement of a primary and secondary caches. It was designed to be used with a primary Cache bound to a fast store and a secondary cache bound to a persistent store implementation

TieredCache(Cache<
T> _primary, Cache<T> _secondary, {CacheManager? manager, String? name, Clock? clock, bool? statsEnabled, CacheStats? stats}) - Builds a TieredCache with a primary and a secondary cache
