Memcached is a high-performance, multithreaded, distributed in-memory key-value cache store used to speed up dynamic web applications by alleviating database load. It stores small chunks of arbitrary data (strings, objects) from database calls, API calls, or page rendering, with client APIs available for most popular languages.

Use cases

• cache database query results to reduce database load
• speed up dynamic web applications with an in-memory key-value store
• share a cache pool across a cluster of web servers
• store session data or rendered page fragments in memory
• cache API call responses for faster reads

When to choose

• you need a simple, battle-tested distributed in-memory cache for small objects
• you want to offload read pressure from a relational database in a web app
• you need a cache with client libraries in nearly every language
• you want a lightweight cache server with optional TLS and a built-in proxy

When to avoid

• you need persistence or durability - memcached is memory-only and loses data on restart
• you need rich data structures, replication, or pub/sub - consider Redis instead
• you need to cache large values or datasets that exceed available RAM
• you need strong consistency guarantees across cache nodes
