Key eviction

Overview of Redis key eviction policies (LRU, LFU, etc.) Redis is commonly used as a cache to speed up read accesses to a slower server or database. Since cache entries are copies of persistently-stored data, it is usually safe to evict them when the cache runs out of memory (they can be cached again in the future if necessary). Redis lets you specify an eviction policy to evict keys automatically
