cachename

CacheName is an identifier used to refer to a specific cache instance within a caching system. It serves as a namespace that allows multiple caches to coexist in the same application or environment, each with its own configuration, policies, and lifecycle. The name is used by the cache manager or API to retrieve, store, and invalidate entries belonging to that cache.

In practice, caches are looked up by name to perform operations such as put, get, and remove. For example, in Java's JCache API a CacheManager retrieves a cache by its name. In Spring Framework’s caching abstraction, the cacheNames attribute or value in annotations designates which named caches should apply to a given operation. In browser-based Cache API usage, caches.open('cacheName') creates or opens a named cache for storing responses and other assets.

Configuration and behavior are typically defined per named cache. A cache named "userSessions" might have a different maximum size, expiration policy, or persistence than a cache named "staticAssets." In distributed or in-memory caches, the name can establish a namespace within a cluster, helping isolate data and control eviction and replication.

Lifecycle considerations include whether a named cache is created lazily on first use or declared at startup, how it is configured, and how it is cleared or destroyed. Good practices emphasize consistent naming across modules, clear documentation of each cache’s purpose, and alignment with overall data freshness and resource constraints. Security and serialization considerations also apply, since access control and the format of cached keys and values can vary by cache.
