  title: Amazon Data Pipeline Redeploy Definition
  summary: Deactivate a pipeline, write a new definition, then reactivate it with the new objects.
  description: >-
    A controlled redeploy flow for AWS Data Pipeline. A running pipeline is
    deactivated so its current schedule stops, the new set of pipeline objects is
    committed with PutPipelineDefinition, and the pipeline is then reactivated to
    resume processing with the updated definition. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Deactivate, replace the definition, and reactivate a pipeline.
  description: >-
    Chains deactivatePipeline, putPipelineDefinition, and activatePipeline so a
    new definition is applied to an existing pipeline without leaving it running
    against a stale or partially written definition.
