The short version

  • Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; Mozilla Firefox no longer supported on Windows 8.1 and earlier versions (users must use Firefox ESR)
  • They diverge on capability: Memcached covers In-memory key-value cache, Mozilla Firefox covers Enhanced tracking protection.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Mozilla Firefox

  • No longer supported on Windows 8.1 and earlier versions (users must use Firefox ESR)
  • No longer supported on macOS 10.14 and earlier versions (users must use Firefox ESR)

Memcached: Memcached or Redis?

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.
