There was a problem hiding this comment.
This refresh logic is required because duckdb doesn't refresh credentials. Ref - duckdb/duckdb-aws#26
TODO: refactor to provide refresh interval as a config.

Problem
Currently the only way to set AWS credentials is via setting the static credentials as environment variables or by passing as a flag when executing.
Some systems already have credentials setup using different ways provided by aws like credentials file, config file or EC2 profiles.
Solution
This PR adds support for using AWS S3 credentials from default credentials provider chain in the SDK.
The order for the AWS SDK golang is documented at [1].
The order for duckdb is documented at [2].
