# Policy: Queue-based Authentication Simulation
#
# This policy simulates a continuous stream of info.json fetch requests. It pulls
# URLs from a Redis queue and processes them, acting as the first stage in a
# two-stage simulation. The second stage (downloading) can be handled in one
# of two ways, configured below:
#
# --- WORKFLOW 1: Queue-Auth -> File-Download ---
#    - This policy creates info.json files in a shared directory (`save_info_json_dir`).
#    - A separate download simulation (e.g., policy 11_direct_docker_download_simulation.yaml)
#      watches that directory, picks up the files, and performs the downloads.
#    - To enable:
#      - Set `create_download_tasks: false`
#      - Ensure `save_info_json_dir` points to a shared path.
#
# --- WORKFLOW 2: Queue-Auth -> Queue-Download ---
#    - This policy creates download *tasks* and pushes them to another Redis queue.
#    - A separate download simulation (e.g., policy 13_queue_download_simulation.yaml)
#      pulls tasks from that queue and performs the downloads.
#    - To enable:
#      - Set `create_download_tasks: true`
#      - Configure `download_task_queue` to the correct queue name.
#      - Use `download_task_granularity` to control if one task is created per-URL
#        or per-format.

execution_control:

info_json_generation_policy:
  # This setting tells the auth worker how many download tasks will be generated
  # per successful info.json. It is used to correctly increment the
  # 'pending_downloads' counter on the auth profile.
  # Can be an integer, or 'from_download_policy' to automatically count formats
  # from the 'download_policy.formats' setting in this same policy file.
  downloads_per_url: "from_download_policy"
  # (For Queue-Download workflow) Controls how download tasks are created.
  #
  # "per_format": (Default) Creates one download task for EACH format specified in 'formats_to_download'.
  #               If `formats_to_download` is "140,299", two download tasks are created, and
  #               the 'pending_downloads' counter is incremented by 2.
  #
  # "per_url":    Creates a SINGLE download task for the entire URL. The 'formats_to_download'
  #               string is passed to the download worker as the format selector, but 'pending_downloads'
  #               is only incremented by 1 for the whole URL.
