R2 is S3 compatible with no egress fees.

Cloudflare actually has built in iceberg support for R2 buckets. It's quite nice.

Combine that with their pipelines it's a simple http request to ingest, then just point duckdb to the iceberg enabled R2 bucket to analyze.

There's no egress data transfer fees, but you still pay for the GET request operations. Lots of little range requests can add up quick.

Can't believe that is what the industry has come down to. Kind like clipping coupon to get the best deal according different pricing overlords.

It is time like this that makes self-hosting a lot more attractive.

For a demo of this (although not sure with duckdb wasm that it works with iceberg) https://andrewpwheeler.com/2025/06/29/using-duckdb-wasm-clou...

Was about to jump in to say the same thing. R2 is a much cheaper alternative to S3 that just works and I have used it with DuckDB, works smoothly
