The short version

  • Only Apache Druid has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apache Druid open-source offering lacks high-availability, distributed architecture, and enterprise security features; Notion AI full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
  • They diverge on capability: Apache Druid covers Real-time Ingestion, Notion AI covers Writing assistance.

What people use each for

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

Notion AI

  • Full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
  • The Free and Plus plans offer trial AI capabilities rather than the full feature set
  • AI is not sold separately from the workspace seat, so every member must be upgraded to reach it
  • Zero data retention with LLM providers is Enterprise only, which is custom priced
