Federation implementation roadmap

Use a remote-hosted workflow

  • When retrieving a workflow record for arvados-cwl-runner, API server notices workflow UUID is remote, and fetches it with salted token (instead of looking in local DB)

Mount remote-hosted collection (read-only) in a container

  • When creating a container to satisfy a CR, API server notices collection UUID in cr.mounts is remote, and fetches it with salted token (instead of looking in local DB)

Run some portions of a CWL workflow on a remote cluster

  • When submitting container requests, a-c-r follows workflow/commandline/input UUID hints to choose a cluster
  • Either a-c-r handles the multi-cluster stuff itself, or it submits CRs with "submit to cluster X" flag, and the API server acts as a proxy
