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).

# UpdateApplication
<a name="API_UpdateApplication"></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).

Updates an existing Amazon Kinesis Analytics application. Using this API, you can update application code, input configuration, and output configuration. 

Note that Amazon Kinesis Analytics updates the `CurrentApplicationVersionId` each time you update your application. 

This operation requires permission for the `kinesisanalytics:UpdateApplication` action.
