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
