AWS::KinesisAnalytics::Application Input

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.

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
}

  KinesisFirehoseInput:

Properties

InputParallelism

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.

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 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.

Required: Conditional

Type: KinesisFirehoseInput

Update requires: No interruption

KinesisStreamsInput

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.

Required: Conditional

Type: KinesisStreamsInput

Update requires: No interruption

NamePrefix

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_001," "MyInApplicationStream_002," and so on.

Required: Yes

Type: String

Minimum: 1

Maximum: 32

Update requires: No interruption
