  title: Amazon DocumentDB Provision Cluster and Await Available
  summary: Create a DocumentDB cluster and poll until it reports the available status.
  description: >-
    Provisions a new Amazon DocumentDB cluster and then polls the cluster
    description endpoint until the cluster transitions out of the creating
    state and reports an available status. The workflow uses the AWS query
    protocol, supplying the Action and Version in the query string and the
    cluster parameters as a form-urlencoded request body, and spells out each
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
