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

Cloudflare announced the open beta of R2 Data Catalog, a managed Apache Iceberg REST catalog built into R2 object storage that brings ACID transactions, schema evolution, time travel, and efficient querying without external catalogs, supporting engines like PyIceberg, Snowflake, and Spark and providing quick-start steps and example code. The post explains Iceberg’s metadata model (schemas, snapshots, partition specs), shows how to enable the catalog, and details current beta pricing (standard R2 rates with no extra catalog fees yet) along with indicative future charges for catalog operations and compaction. The roadmap includes automatic compaction and expanded compatibility with the Iceberg REST Catalog spec, with invitations for feedback via the Cloudflare Developer Discord and links to documentation.
