-- This documentation is for version 1 of the Amazon Kinesis Data Analytics

-- Stops the application from processing input data. You can stop an
-- application only if it is in the running state. You can use the
-- <https://docs.aws.amazon.com/kinesisanalytics/latest/dev/API_DescribeApplication.html DescribeApplication>
-- operation to find the application state. After the application is
-- stopped, Amazon Kinesis Analytics stops reading data from the input, the
-- application stops processing data, and there is no output written to the
-- destination.
--
-- This operation requires permissions to perform the
-- @kinesisanalytics:StopApplication@ action.
