Each strategy is explained with how it works, best use cases, pros and cons, and where applicable, a code example using Redis. TTL removes items after a fixed time, LRU evicts the least recently accessed, LFU removes the least frequently accessed, MRU evicts the most recently accessed (useful for streaming/batch workloads), and SLRU splits the cache into probationary and protected segments for a hybrid approach. ## Full article daily.dev links to this article rather than hosting it.
