Specifying the S3A endpoint (fs.s3a.endpoint) is
- required for regions which only support v4 authentication
- A good practice for all regions.
The user experience of having to configure endpoints is not great. Often it is neglected and leads to additional cost, reduced performance, or failures for v4 auth regions.
I want to explore an option which, when enabled, auto-detects the region for an s3 bucket and uses the proper endpoint. Not sure if this is possible or anyone has looked into it yet.
