  title: Amazon Neptune Bulk Load Job Lifecycle
  summary: Start a bulk load via the Loader endpoint, verify it appears in the job
    list, and poll its status.
  description: Drives the full lifecycle of a Neptune bulk load through the dedicated
    Loader REST endpoint. The workflow starts a bulk load job from Amazon S3, lists
    the recent load job ids to confirm the new job is tracked, and then polls the
    job status on a loop until the overall status reaches LOAD_COMPLETED. A poll loop
    handles LOAD_IN_PROGRESS. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
