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; Clay two separate meters run at once, actions and data credits, and a plan can exhaust either independently
  • They diverge on capability: Apache Druid covers Real-time Ingestion, Clay covers Data enrichment.

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

Clay

  • Two separate meters run at once, actions and data credits, and a plan can exhaust either independently
  • Data credit overage is sold at a 30% premium over the plan rate, so exceeding the allowance costs more per unit than planning for it
  • The free plan allows 500 actions, 100 data credits and 200 rows per table
  • The entry paid plan starts at $167 a month, and both paid prices are starting figures rather than fixed
  • The free plan cannot buy overage at all, so hitting the limit stops work rather than billing for it
