Where each one falls short

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

Oracle Cloud

  • The free trial gives US$300 of credit that expires when consumed or after 30 days, whichever comes first
  • The US$300 cloud credit is available only in select countries
  • Only one Oracle Cloud Free Trial or Always Free account is permitted per person
  • Accounts left idle for 30 days or more are eligible for suspension or termination as abandoned
  • Always Free NoSQL Database is restricted to the Phoenix region
  • Free Tier availability is subject to capacity limits, and the published per-service capacity figures are estimates that assume the entire credit is spent on that one service

QuestDB

  • Open-source edition lacks high-availability, distributed architecture, and enterprise security features
  • Enterprise edition pricing not published; requires contacting sales for custom quote
  • Ingestion limit of 20M rows/sec platform-dependent; may not scale to extreme throughput requirements
