Key points

  • Redis: rich data structures, optional persistence, built-in replication/failover, pub/sub
  • Memcached: simple key-value only, no persistence, no built-in replication, native multi-threading
  • Redis is the more commonly chosen default for new deployments due to its broader feature set
  • Memcached remains a reasonable choice for pure, simple, high-throughput ephemeral caching
