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; Elastic the 99.95% monthly uptime SLA is only offered on the Platinum and Enterprise subscription tiers of Hosted deployments, not on lower tiers, per elastic.co, August 2026

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

Elastic

  • The 99.95% monthly uptime SLA is only offered on the Platinum and Enterprise subscription tiers of Hosted deployments, not on lower tiers, per elastic.co, August 2026
