Where each one falls short

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

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

Redis

  • Licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • All data must fit in memory, limiting scalability to available RAM
  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases
