Module: ActiveSupport::Cache::Strategy::LocalCache
- Included in:
- FileStore, MemCacheStore, NullStore
- Defined in:
- lib/active_support/cache/strategy/local_cache.rb,
lib/active_support/cache/strategy/local_cache_middleware.rb
Overview
Caches that implement LocalCache will be backed by an in-memory cache for the duration of a block. Repeated calls to the cache for the same key will hit the in-memory cache for faster access.
Defined Under Namespace
Classes: LocalCacheRegistry, LocalStore, Middleware
