  title: Amazon ElastiCache Provision Replication Group
  summary: Create a Redis replication group and poll until it becomes available.
  description: >-
    Provisions a new Amazon ElastiCache Redis replication group and waits for it
    to finish coming online. The workflow submits a CreateReplicationGroup
    request, captures the returned replication group identifier, and repeatedly
    calls DescribeReplicationGroups until the group reports it is available.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description. Requests use the
    AWS query (x-www-form-urlencoded) protocol with the Action and Version query
    parameters that the ElastiCache API requires.

  summary: Create a replication group and wait for it to become available.
  description: >-
    Creates a Redis replication group with the supplied identifier and node
    configuration, then polls DescribeReplicationGroups until the group reports
    it is available.
  inputs:
    type: object
    required:
    - ReplicationGroupId
    - ReplicationGroupDescription
    - CacheNodeType
    - NumCacheClusters
    properties:
      ReplicationGroupId:
        type: string
        description: The replication group identifier.
      ReplicationGroupDescription:
        type: string
        description: A user-created description for the replication group.
      CacheNodeType:
        type: string
        description: The compute and memory capacity of the nodes in the node group.
      NumCacheClusters:
        type: integer
        description: The number of clusters this replication group initially has.
      AutomaticFailoverEnabled:
        type: boolean

  steps:
  - stepId: createGroup
    description: >-
      Submit a CreateReplicationGroup request for the supplied identifier and
      node configuration. The Action and Version query parameters identify the
      AWS operation; the group attributes travel in the form-encoded body.

    description: >-
      Describe the just-created replication group and confirm it has reached an
      available status. The ReplicationGroupId query parameter scopes the
      description to the single group created in the previous step.
