AWS::KinesisAnalyticsV2::Application Input

When you configure the application input for a SQL-based Kinesis Data Analytics application, you specify the streaming source, the in-application stream name that is created, and the mapping between the two.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON


{
  "InputParallelism" : InputParallelism,
  "InputProcessingConfiguration" : InputProcessingConfiguration,
  "InputSchema" : InputSchema,
  "KinesisFirehoseInput" : KinesisFirehoseInput,
  "KinesisStreamsInput" : KinesisStreamsInput,
  "NamePrefix" : String
}

YAML


  InputParallelism: 
    InputParallelism
  InputProcessingConfiguration: 
    InputProcessingConfiguration
  InputSchema: 
    InputSchema
  KinesisFirehoseInput: 
    KinesisFirehoseInput
  KinesisStreamsInput: 
    KinesisStreamsInput
  NamePrefix: String

Properties

InputParallelism

Describes the number of in-application streams to create.

Required: No

Type: InputParallelism

Update requires: No interruption

InputProcessingConfiguration

The InputProcessingConfiguration 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.

Required: No

Type: InputProcessingConfiguration

Update requires: No interruption

InputSchema

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.

Required: Yes

Type: InputSchema

Update requires: No interruption

KinesisFirehoseInput

If the streaming source is an Amazon Kinesis Data Firehose delivery stream, identifies the delivery stream's ARN.

Required: No

Type: KinesisFirehoseInput

Update requires: No interruption

KinesisStreamsInput

If the streaming source is an Amazon Kinesis data stream, identifies the stream's Amazon Resource Name (ARN).

Required: No

Type: KinesisStreamsInput

Update requires: No interruption

NamePrefix

The name prefix to use when creating an in-application stream. Suppose that you specify a prefix "MyInApplicationStream." Kinesis Data Analytics then creates one or more (as per the InputParallelism count you specified) in-application streams with the names "MyInApplicationStream_001," "MyInApplicationStream_002," and so on.

Required: Yes

Type: String

Pattern: ^[^-\s<>&]*$

Minimum: 1

Maximum: 32

Update requires: No interruption
