Method: Marty::CacheAdapters::MemoryAndRedis#fetch_item

Defined in:
lib/marty/cache_adapters/memory_and_redis.rb

#fetch_item(klass:, cache_key:, default: nil) ⇒ Object

When cache is found in local memory, we simply return the cached item. Otherwise we look into Redis, if item is cached there, we copy it to local memory to speed up future lookups.
