Redis vs Memcached: which should you choose?
Redis is far more than a cache — it offers persistence, pub/sub, streams, and rich data structures, making it a general-purpose in-memory store. Memcached does one thing, simple key/value caching, extremely well and with minimal memory overhead. Choose Redis when you need durability and features; choose Memcached for the leanest possible caching layer.
