Type: Timestamp  
Required: No

 ** pipelineArn **   <a name="CodePipeline-Type-PipelineMetadata-pipelineArn"></a>
The Amazon Resource Name (ARN) of the pipeline.

 ** pollingDisabledAt **   <a name="CodePipeline-Type-PipelineMetadata-pollingDisabledAt"></a>
The date and time that polling for source changes (periodic checks) was stopped for the pipeline, in timestamp format.   
Pipelines that are inactive for longer than 30 days will have polling disabled for the pipeline. For more information, see [pollingDisabledAt](https://docs.aws.amazon.com/codepipeline/latest/userguide/reference-pipeline-structure.html#metadata.pollingDisabledAt) in the pipeline structure reference. For the steps to migrate your pipeline from polling to event-based change detection, see [Migrate polling pipelines to use event-based change detection](https://docs.aws.amazon.com/codepipeline/latest/userguide/update-change-detection.html).
You can migrate (update) a polling pipeline to use event-based change detection. For example, for a pipeline with a CodeCommit source, we recommend you migrate (update) your pipeline to use CloudWatch Events. To learn more, see [Migrate polling pipelines to use event-based change detection](https://docs.aws.amazon.com/codepipeline/latest/userguide/update-change-detection.html) in the * AWS CodePipeline User Guide*.
