  title: Amazon DynamoDB Provision a Table
  summary: Create a DynamoDB table and poll until it becomes ACTIVE.
  description: >-
    Provisions a new DynamoDB table and waits for it to finish creating.
    The workflow submits a CreateTable request with a primary key schema
    and throughput settings, then repeatedly describes the table until its
    TableStatus transitions out of CREATING and reaches ACTIVE. Every step
    spells out its request inline, including the AWS JSON protocol
    X-Amz-Target header, so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Create a table and wait for it to become ACTIVE.
  description: >-
    Submits a CreateTable request and then polls DescribeTable until the
    reported TableStatus is ACTIVE, branching back to the describe step
    while the table is still being created.
