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);
