1.1 (stable)
Cloudflare R2 Import
Prerequisites
For Cloudflare R2, the S3 Compatibility API allows you to use DuckDB's S3 support to read and write from R2 buckets.
This requires the httpfs
extension, which can be installed using the INSTALL
SQL command. This only needs to be run once.
Credentials and Configuration
You will need to generate an S3 auth token and create an R2
secret in DuckDB:
CREATE SECRET (
TYPE R2,
KEY_ID 'AKIAIOSFODNN7EXAMPLE',
SECRET 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY',
ACCOUNT_ID 'your-account-id-here' -- your 33 character hexadecimal account ID
);
Querying
After setting up the R2 credentials, you can query the R2 data using DuckDB's built-in methods, such as read_csv
or read_parquet
:
SELECT * FROM read_parquet('r2://⟨r2_bucket_name⟩/⟨file⟩');
