LOAD httpfs;

After loading the HTTPFS extension, set up the credentials and S3 region to read data. You may either use an access key and secret, or a token.

SET s3_region='us-east-1';
SET s3_access_key_id='<AWS access key id>';
SET s3_secret_access_key='<AWS secret access key>';

The alternative is to use a token:

SET s3_region='us-east-1';
SET s3_session_token='<AWS session token>';

After the HTTPFS extension is set up and the S3 credentials are correctly configured, Parquet files can be read from S3 using the following command:

SELECT * FROM read_parquet('s3://<bucket>/<file>');
