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|
