describe_application#

KinesisAnalytics.Client.describe_application(**kwargs)#

Note

This documentation is for version 1 of the Amazon Kinesis Data Analytics API, which only supports SQL applications. Version 2 of the API supports SQL and Java applications. For more information about version 2, see Amazon Kinesis Data Analytics API V2 Documentation.

Returns information about a specific Amazon Kinesis Analytics application.

If you want to retrieve a list of all applications in your account, use the ListApplications operation.

This operation requires permissions to perform the kinesisanalytics:DescribeApplication action. You can use DescribeApplication to get the current application versionId, which you need to call other operations such as Update.
