Where each one falls short

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

Apache Druid

  • Open-source offering lacks high-availability, distributed architecture, and enterprise security features
  • Requires native integration with Apache Kafka or Amazon Kinesis for real-time ingestion; custom integrations need development
  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

dbt

  • Free tier severely limited to one developer seat and 3,000 models/month
  • Starter plan at $100/user/month for each additional seat adds costs for team collaboration
  • Requires existing data warehouse; not suitable for teams without cloud warehouse investment
