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; Oracle Database high licensing costs for Enterprise Edition with option packs potentially doubling the effective per-processor cost
  • They diverge on capability: Memcached covers In-memory key-value cache, Oracle Database covers PL/SQL.

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

Oracle Database

  • High licensing costs for Enterprise Edition with option packs potentially doubling the effective per-processor cost
  • Requires skilled database administrators for proper setup, configuration, and maintenance
  • High hardware requirements increase infrastructure costs; less suitable for resource-constrained environments
