Where each one falls short

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

Materialize

  • Community tier limited to 24GB memory, restricting production deployments
  • Compute credit pricing requires predicting usage patterns
  • Learning SQL transformation models adds complexity vs pre-built solutions
  • Self-managed deployments require operational expertise

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
