This AWS Solutions Konstruk deploys a Kinesis Stream and Lambda function with the appropriate resources/properties for interaction and security.

Here is a minimal deployable pattern definition:

const { KinesisStreamsToLambda } = require('@aws-solutions-konstruk/aws-kinesisstreams-lambda');

new KinesisStreamsToLambda(stack, 'KinesisToLambdaPattern', {
    deployLambda: true,
    eventSourceProps: {
        startingPosition: lambda.StartingPosition.TRIM_HORIZON,
        batchSize: 1
    },
    lambdaFunctionProps: {
        runtime: lambda.Runtime.NODEJS_10_X,
        handler: 'index.handler',
        code: lambda.Code.asset(`${__dirname}/lambda`)
    }
});

Initializer

new KinesisStreamsToLambda(scope: Construct, id: string, props: KinesisStreamsToLambdaProps);

Parameters

• scope Construct
• id string
• props KinesisStreamsToLambdaProps

Pattern Construct Props

Name	Type	Description
deployLambda	boolean	Whether to create a new Lambda function or use an existing Lambda function. If set to false, you must provide an existing function for the existingLambdaObj property.
existingLambdaObj?	lambda.Function	An optional, existing Lambda function. This property is required if deployLambda is set to false.
lambdaFunctionProps?	lambda.FunctionProps	Optional user-provided props to override the default props for the Lambda function. This property is only required if deployLambda is set to true.
kinesisStreamProps?	kinesis.StreamProps	Optional user-provided props to override the default props for the Kinesis stream.
eventSourceProps?	lambda.EventSourceMappingOptions	Optional user-provided props to override the default props for the Lambda event source mapping.
encryptionKeyProps?	kms.KeyProps	Optional user-provided props to override the default props for the KMS encryption key.

Pattern Properties

Name	Type	Description
stream()	kinesis.Stream	Returns an instance of the Kinesis stream created by the pattern.
lambdaFunction()	lambda.Function	Returns an instance of the Lambda function created by the pattern.
