-- | 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 list of tags to associate with the pipeline at creation. Tags let you
-- control access to pipelines. For more information, see <http://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-control-access.html Controlling UserAccess to Pipelines> in the /AWS Data Pipeline Developer Guide/.

-- | 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.
