  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

Looker

  • No pricing published on website; quote-based model requires contacting Google Cloud sales
  • Pricing typically based on user count, deployment type, and feature requirements with no transparency
