After careful consideration, we have decided to discontinue Amazon Kinesis Data Analytics for SQL applications:

1. From **September 1, 2025**, we won't provide any bug fixes for Amazon Kinesis Data Analytics for SQL applications because we will have limited support for it, given the upcoming discontinuation.

2. From **October 15, 2025**, you will not be able to create new Kinesis Data Analytics for SQL applications.

3. We will delete your applications starting **January 27, 2026**. You will not be able to start or operate your Amazon Kinesis Data Analytics for SQL applications. Support will no longer be available for Amazon Kinesis Data Analytics for SQL from that time. For more information, see [Amazon Kinesis Data Analytics for SQL Applications discontinuation](discontinuation.md).

# DescribeApplication
<a name="API_DescribeApplication"></a>

**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](/kinesisanalytics/latest/apiv2/Welcome.html).

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](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/API_ListApplications.html) 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`.
