Cloudflare R2 SQL API

The Cloudflare R2 SQL API enables developers to query data stored in R2 using standard SQL syntax including JOINs, subqueries, and multi-table queries (added May 2026). It provides a serverless query engine for analyzing Iceberg tables and structured data in R2 buckets without requiring separate data warehouse infrastructure.
