CfnApplicationReferenceDataSource

Adds a reference data source to an existing application. Amazon Kinesis Analytics reads reference data (that is, an Amazon S3 object) and creates an in-application table within your application. In the request, you provide the source (S3 bucket name and object key name), name of the in-application table to create, and the necessary mapping information that describes how data in Amazon S3 object maps to columns in the resulting in-application table. For conceptual information, see [Configuring Application Input](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/how-it-works-input.html) . For the limits on data sources you can add to your application, see [Limits](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/limits.html) . This operation requires permissions to perform the `kinesisanalytics:AddApplicationOutput` action.
