Prerequisites
For Cloudflare R2, the [S3 Compatibility API](https://developers.cloudflare.com/r2/api/s3/api/) allows you to use DuckDB's S3 support to read and write from R2 buckets.  
This requires the [`httpfs` extension](#docs:extensions:httpfs:overview), which can be installed using the `INSTALL` SQL command. This only needs to be run once.
