AddApplicationInput

Adds a streaming source to your SQL-based Kinesis Data Analytics application.

You can add a streaming source when you create an application, or you can use this operation to add a streaming source after you create an application. For more information, see CreateApplication.

Any configuration update, including adding a streaming source using this operation, results in a new version of the application. You can use the DescribeApplication operation to find the current application version.
