This AWS Solutions Konstruk implements a pattern Amazon DynamoDB table with stream to invoke the AWS Lambda function with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { DynamoDBStreamToLambdaProps,  DynamoDBStreamToLambda} = require('@aws-solutions-konstruk/aws-dynamodb-stream-lambda');

const props: DynamoDBStreamToLambdaProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler'
    },
};

new DynamoDBStreamToLambda(stack, 'test-dynamodb-stream-lambda', props);

Initializer

new DynamoDBStreamToLambda(scope: Construct, id: string, props: DynamoDBStreamToLambdaProps);

Parameters

• scope Construct
• id string
• props DynamoDBStreamToLambdaProps

Pattern Construct Props

Name	Type	Description
deployLambda	boolean	Whether to create a new Lambda function or use an existing Lambda function
existingLambdaObj?	lambda.Function	Existing instance of Lambda Function object
lambdaFunctionProps?	lambda.FunctionProps	Optional user provided props to override the default props for Lambda function
dynamoTableProps?	dynamodb.TableProps	Optional user provided props to override the default props for DynamoDB Table
dynamoEventSourceProps?	aws-lambda-event-sources.DynamoEventSourceProps	Optional user provided props to override the default props for DynamoDB Event Source

Pattern Properties

Name	Type	Description
dynamoTable()	dynamodb.Table	Returns an instance of dynamodb.Table created by the construct
lambdaFunction()	lambda.Function	Returns an instance of lambda.Function created by the construct
