For new projects, we recommend that you use the new Kinesis Data Analytics Studio over Kinesis Data Analytics for SQL Applications. Kinesis Data Analytics Studio combines ease of use with advanced analytical capabilities, enabling you to build sophisticated stream processing applications in minutes.
DescribeApplication
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.
