-- | A list of tags to associate with the pipeline at creation. Tags let you

-- | The name for the pipeline. You can use the same name for multiple
-- pipelines associated with your AWS account, because AWS Data Pipeline
-- assigns each pipeline a unique pipeline identifier.
cpName :: Lens' CreatePipeline Text
cpName = lens _cpName (\ s a -> s{_cpName = a});

-- | A unique identifier. This identifier is not the same as the pipeline
-- identifier assigned by AWS Data Pipeline. You are responsible for
-- defining the format and ensuring the uniqueness of this identifier. You
-- use this parameter to ensure idempotency during repeated calls to
-- 'CreatePipeline'. For example, if the first call to 'CreatePipeline'
-- does not succeed, you can pass in the same unique identifier and
-- pipeline name combination on a subsequent call to 'CreatePipeline'.
-- 'CreatePipeline' ensures that if a pipeline already exists with the same
-- name and unique identifier, a new pipeline is not created. Instead,
-- you\'ll receive the pipeline identifier from the previous attempt. The
-- uniqueness of the name and unique identifier combination is scoped to
-- the AWS account or IAM user credentials.
