AWS SNSからLambda連携をCDKで

import * as sns from '@aws-cdk/aws-sns';
import { SnsEventSource } from '@aws-cdk/aws-lambda-event-sources';

const topic = new sns.Topic(...);
const deadLetterQueue = new sqs.Queue(this, 'deadLetterQueue');

lambda.addEventSource(new SnsEventSource(topic, {
  filterPolicy: { ... },
  deadLetterQueue: deadLetterQueue
}));
