Cloudflare Basin: Serverless Data Platform Now Generally Available

Cloudflare has announced the general availability of Cloudflare Basin, a serverless data analytics platform built on Apache Iceberg and R2 Object Storage. Formerly known as the Cloudflare Data Platform, Basin unifies ingestion, storage, and querying into a single suite designed for speed, openness, and cost efficiency.

Core Components

The Basin family consists of three integrated products:

• Basin Pipelines: Ingests events from Workers, HTTP, or Logpush, transforms them with SQL, and writes them as Iceberg tables or files in R2. It now supports ingestion speeds of up to 3GB/s per stream.
• Basin Catalog: Manages Iceberg metadata and automatically maintains tables through compaction, snapshot expiration, and manifest optimization to ensure performance.
• Basin SQL: A serverless, distributed SQL engine that queries Iceberg tables directly on Cloudflare’s network, supporting over 190 scalar and aggregate functions.

Key Advantages

Basin leverages R2’s zero egress fees to enable data portability across regions and cloud providers. Developers can read and write data using any Iceberg-compatible engine, including PyIceberg, DuckDB, Snowflake, and Apache Spark. The platform uses usage-based pricing, charging only for ingestion, processing, and queries, with no hourly infrastructure costs.

Future Roadmap

Cloudflare plans to expand Basin with support for Apache Iceberg V3, including the Variant type, and advanced features like stateful processing for streaming aggregations. The long-term vision is to abstract data infrastructure entirely, allowing developers to focus on analytical questions rather than resource management.
