  title: EventBridge Pipes Drain and Delete Pipe
  summary: Safely decommission a pipe by stopping it, polling until it is STOPPED, then deleting it.
  description: >-
    Deleting a running pipe can interrupt in-flight events, so the safe
    decommission pattern is to stop the pipe first, wait until it has fully
    reached the STOPPED state, and only then delete it. This workflow issues
    StopPipe, polls DescribePipe until CurrentState is STOPPED, and finally
    calls DeletePipe. Each step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
