Is there an equivalent API in datafusion?
The equivalent can be specified as part of each external table definition. For example https://datafusion.apache.org/user-guide/cli/datasources.html#s3
CREATE EXTERNAL TABLE test
STORED AS PARQUET
OPTIONS(
'aws.access_key_id' '******',
'aws.secret_access_key' '******',
'aws.region' 'us-east-2'
)
LOCATION 's3://bucket/path/file.parquet';
This isn't quite as good as a secret that can be reused but it should work

I am pretty interesting in this idea. I saw duckdb just implements Hugging face Authentications via
CREATE SECRET hf_token (
TYPE HUGGINGFACE,
TOKEN 'your_hf_token'
);
or
CREATE SECRET hf_token (
TYPE HUGGINGFACE,
PROVIDER CREDENTIAL_CHAIN
);

Hey @alamb, need some help while implementing the wildcard functions. Did datafusion support select from a wildcard of external files, e.g., select * from 's3://some-bucket/test/*.parquet'. I read through the doc but failed to find a proper example..
I don't think it supports wildcards but instead the Listing table to read all the files in a directory (that have the correct extension):
https://datafusion.apache.org/user-guide/sql/ddl.html#create-external-table
CREATE EXTERNAL TABLE test
STORED AS CSV
LOCATION '/path/to/directory/of/files'
OPTIONS ('has_header' 'true');
