    "description": "In-memory key/value store providing sub-millisecond reads for frequently\naccessed data, reducing load on the primary database and improving\nresponse latency. Caching strategies include cache-aside, read-through,\nwrite-through, and write-behind patterns.\n\nRedis (the dominant choice) supports rich data structures (hashes, sorted\nsets, streams), pub/sub, Lua scripting, and optional persistence via RDB\nand AOF. Memcached is simpler but faster for pure caching. Varnish\noperates at the HTTP layer for full-page or fragment caching. Key\noperational concerns include cache invalidation strategies, TTL tuning,\neviction policies (LRU, LFU), and hot-key management in clustered setups.\n"
