Motivation

Allow users to explicitly configure the STS endpoint that should be used.

Solution

• Add the following config options for the S3 file system

  • fs.s3a.sts.endpoint: The endpoint URL of the AWS Security Token Service to use for authenticating to S3.
  • fs.s3a.sts.region: The region to use for SigV4 signing of requests. If not set, fs.s3a.region will be used.

• If fs.s3a.sts.endpoint is set, build the STS client in src/main/java/com/alibaba/fluss/fs/s3/token/S3DelegationTokenProvider.java with the desired endpoint configuration.

Anything else?
