Depends

Should I use memcached - a distributed memory object caching system?

· 1 month ago

A free, battle-tested distributed cache that fits teams with real database load and ops capacity to run it. Overkill for small apps that can cache in-process or pay for a managed option.

Gotchas - check before you buy

Slab classes can starve as object sizes change, effectively shrinking your cache

Classic per-web-server caching is wasteful; pooled deployment takes extra setup effort

Pros and cons

Pros

  • Free and open-source; no license fees
  • Simple design promotes quick deployment and easy development
  • Pools cache across web farm; 50 servers yield 3.2GB usable cache

  • Battle-tested; subject of academic thread-scalability and memory research

Cons

  • In-memory key-value store only; no richer data features
  • Ten known vulnerabilities tracked publicly
  • Official security page not found in sources reviewed
  • Manual install, CLI configuration, self-managed; no first-party managed offering
