R2 Data Catalog: Managed Apache Iceberg tables with zero egress fees

What this post added

This post introduces the R2 Data Catalog, a managed Apache Iceberg catalog built directly into Cloudflare R2 buckets. This feature simplifies querying large analytic datasets stored in object storage by providing database-like capabilities (ACID transactions, schema evolution) without the overhead of managing external data catalogs or incurring egress fees. It also details Apache Iceberg's functionality and how it works with object storage, and provides a guide for creating the first Iceberg table on R2.
