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).

# Input
<a name="API_Input"></a>

When you configure the application input, you specify the streaming source, the in-application stream name that is created, and the mapping between the two. For more information, see [Configuring Application Input](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/how-it-works-input.html). 

## Contents
<a name="API_Input_Contents"></a>

 ** InputSchema **   <a name="analytics-Type-Input-InputSchema"></a>
Describes the format of the data in the streaming source, and how each data element maps to corresponding columns in the in-application stream that is being created.  
Also used to describe the format of the reference data source.  
Type: [SourceSchema](API_SourceSchema.md) object  
Required: Yes

 ** NamePrefix **   <a name="analytics-Type-Input-NamePrefix"></a>
Name prefix to use when creating an in-application stream. Suppose that you specify a prefix "MyInApplicationStream." Amazon Kinesis Analytics then creates one or more (as per the `InputParallelism` count you specified) in-application streams with names "MyInApplicationStream\$1001," "MyInApplicationStream\$1002," and so on.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 32.  
Required: Yes

 ** InputParallelism **   <a name="analytics-Type-Input-InputParallelism"></a>
Describes the number of in-application streams to create.   
Data from your source is routed to these in-application input streams.  
 (see [Configuring Application Input](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/how-it-works-input.html).  
Type: [InputParallelism](API_InputParallelism.md) object  
Required: No

 ** InputProcessingConfiguration **   <a name="analytics-Type-Input-InputProcessingConfiguration"></a>
The [InputProcessingConfiguration](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/API_InputProcessingConfiguration.html) for the input. An input processor transforms records as they are received from the stream, before the application's SQL code executes. Currently, the only input processing configuration available is [InputLambdaProcessor](https://docs.aws.amazon.com/kinesisanalytics/latest/dev/API_InputLambdaProcessor.html).  
Type: [InputProcessingConfiguration](API_InputProcessingConfiguration.md) object  
Required: No

 ** KinesisFirehoseInput **   <a name="analytics-Type-Input-KinesisFirehoseInput"></a>
If the streaming source is an Amazon Kinesis Firehose delivery stream, identifies the delivery stream's ARN and an IAM role that enables Amazon Kinesis Analytics to access the stream on your behalf.  
Note: Either `KinesisStreamsInput` or `KinesisFirehoseInput` is required.  
Type: [KinesisFirehoseInput](API_KinesisFirehoseInput.md) object  
Required: No

 ** KinesisStreamsInput **   <a name="analytics-Type-Input-KinesisStreamsInput"></a>
If the streaming source is an Amazon Kinesis stream, identifies the stream's Amazon Resource Name (ARN) and an IAM role that enables Amazon Kinesis Analytics to access the stream on your behalf.  
Note: Either `KinesisStreamsInput` or `KinesisFirehoseInput` is required.  
Type: [KinesisStreamsInput](API_KinesisStreamsInput.md) object  
Required: No
