The short version

  • Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; Readyset pricing requires contacting sales team, making cost planning difficult
  • They diverge on capability: PostgreSQL covers ACID Compliance, Readyset covers Automatic Query Optimization.

Where each one falls short

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

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method

Readyset

  • Pricing requires contacting sales team, making cost planning difficult
  • Specific pricing tiers not disclosed publicly
  • Requires cache size estimation for cost calculation
  • Limited to read query caching, does not address write performance
