Amazon S3

Configure Amazon S3 credentials

You can safely store your Amazon S3 credentials in MotherDuck for convenience by creating a SECRET object using the CREATE SECRET command.

Create a SECRET object

note

The documentation provided relies on DuckDB version 0.10.x. To update to this version, please visit our migration page.

SQL

-- to configure a secret manually:
CREATE SECRET IN MOTHERDUCK (
    TYPE S3,
    KEY_ID 'access_key',
    SECRET 'secret_key',
    REGION 'us-east-1'
);

-- to store a secret configured through `aws configure`:
CREATE SECRET aws_secret IN MOTHERDUCK (
      TYPE S3,
      PROVIDER credential_chain
  );

-- test the s3 credentials
SELECT count(*) FROM 's3://<bucket>/<file>';

Python

import duckdb

con = duckdb.connect('md:')
con.sql("CREATE SECRET IN MOTHERDUCK (TYPE S3, KEY_ID 'access_key', SECRET 'secret_key', REGION 'us-east-1')");

# testing that our s3 credentials work
con.sql("SELECT count(*) FROM 's3://<bucket>/<file>'").show()
# 42

UI

Click on your profile to access the Settings panel and click on Secrets menu.

Then click on Add secret in the secrets section.

You will then be prompted to enter your Amazon S3 credentials.

You can update your secret by executing CREATE OR REPLACE SECRET command to overwrite your secret.

Delete a SECRET object

SQL

You can use the same method above, using the DROP SECRET command.

DROP SECRET <secret_name>;

UI

Click on your profile and access the Settings menu. Click on the bin icon to delete your current secrets.

Amazon S3 credentials as temporary secrets

MotherDuck supports DuckDB syntax for providing S3 credentials.

CREATE SECRET (
    TYPE S3,
    KEY_ID 's3_access_key',
    SECRET 's3_secret_key',
    REGION 'us-east-1'
);

note

Local/In-memory secrets are not persisted across sessions.
