  Derived from Alluxio docs rather than an OpenAPI spec (Alluxio publishes no OpenAPI). Alluxio is
  self-hosted, so authentication is a deployment configuration, not a hosted credential issuer.
summary:
  types: [http-signature, none, tls-mutual]
  interfaces: [s3-api, posix-fuse, python-fsspec]
schemes:
  - name: s3-simple-auth
    interface: S3 API
    type: http
    scheme: aws-signature-v4
    description: >-
      The S3-compatible REST API parses the AWS Signature V4 Authorization header to extract the
      username. Under the default SIMPLE mode the signature itself is NOT validated and the secret
      key may be any non-empty string; if no access key is provided, operations run as the worker
      process user.
