    This AWS Solutions Construct implements Amazon DynamoDB table with stream, AWS Lambda function and Amazon Elasticsearch Service with the least privileged permissions.

    Here is a minimal deployable pattern definition:


    import { Construct } from 'constructs';
    import { Stack, StackProps, Aws } from 'aws-cdk-lib';
    import { DynamoDBStreamsToLambdaToElasticSearchAndKibana, DynamoDBStreamsToLambdaToElasticSearchAndKibanaProps } from '@aws-solutions-constructs/aws-dynamodbstreams-lambda-elasticsearch-kibana';
    import * as lambda from 'aws-cdk-lib/aws-lambda';
    const constructProps: DynamoDBStreamsToLambdaToElasticSearchAndKibanaProps = {
      lambdaFunctionProps: {
        code: lambda.Code.fromAsset(`lambda`),
        runtime: lambda.Runtime.NODEJS_14_X,
        handler: 'index.handler'
      domainName: 'test-domain',
      // TODO: Ensure the Cognito domain name is globally unique
      cognitoDomainName: 'globallyuniquedomain' + Aws.ACCOUNT_ID
    new DynamoDBStreamsToLambdaToElasticSearchAndKibana(this, 'test-dynamodbstreams-lambda-elasticsearch-kibana', constructProps);


    from aws_solutions_constructs.aws_dynamodbstreams_lambda_elasticsearch_kibana import DynamoDBStreamsToLambdaToElasticSearchAndKibana, DynamoDBStreamsToLambdaToElasticSearchAndKibanaProps
    from aws_cdk import (
        aws_lambda as _lambda,
    from constructs import Construct
        self, 'test-dynamodbstreams-lambda-elasticsearch-kibana',
        # TODO: Ensure the Cognito domain name is globally unique
        cognito_domain_name='globallyuniquedomain' + Aws.ACCOUNT_ID)


    import software.constructs.Construct;
    new DynamoDBStreamsToLambdaToElasticSearchAndKibana(this, "test-dynamodb-stream-lambda-elasticsearch-kibana",
            new DynamoDBStreamsToLambdaToElasticSearchAndKibanaProps.Builder()
                    .lambdaFunctionProps(new FunctionProps.Builder()
                    .cognitoDomainName("globallyuniquedomain" + Aws.ACCOUNT_ID)

    Pattern Construct Props

    Name Type Description
    existingLambdaObj? lambda.Function Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error.
    lambdaFunctionProps? lambda.FunctionProps User provided props to override the default props for the Lambda function.
    dynamoTableProps? dynamodb.TableProps Optional user provided props to override the default props for DynamoDB Table
    existingTableInterface? dynamodb.ITable Existing instance of DynamoDB table object or interface, providing both this and dynamoTableProps will cause an error.
    dynamoEventSourceProps? aws-lambda-event-sources.DynamoEventSourceProps Optional user provided props to override the default props for DynamoDB Event Source
    esDomainProps? elasticsearch.CfnDomainProps Optional user provided props to override the default props for the Elasticsearch Service
    domainName string Domain name for the Cognito and the Elasticsearch Service
    createCloudWatchAlarms boolean Whether to create recommended CloudWatch alarms

    Pattern Properties

    Name Type Description
    dynamoTableInterface dynamodb.ITable Returns an instance of dynamodb.ITable created by the construct
    dynamoTable? dynamodb.Table Returns an instance of dynamodb.Table created by the construct. IMPORTANT: If existingTableInterface was provided in Pattern Construct Props, this property will be undefined
    lambdaFunction lambda.Function Returns an instance of lambda.Function created by the construct
    userPool cognito.UserPool Returns an instance of cognito.UserPool created by the construct
    userPoolClient cognito.UserPoolClient Returns an instance of cognito.UserPoolClient created by the construct
    identityPool cognito.CfnIdentityPool Returns an instance of cognito.CfnIdentityPool created by the construct
    elasticsearchDomain elasticsearch.CfnDomain Returns an instance of elasticsearch.CfnDomain created by the construct
    elasticsearchDomain iam.Role Returns an instance of iam.Role created by the construct for elasticsearch.CfnDomain
    cloudwatchAlarms? cloudwatch.Alarm[] Returns a list of cloudwatch.Alarm created by the construct

    Lambda Function

    This pattern requires a lambda function that can post data into the Elasticsearch from DynamoDB stream. A sample function is provided here.

    Default settings

    Out of the box implementation of the Construct without any override will set the following defaults:

    Amazon DynamoDB Table

    • Set the billing mode for DynamoDB Table to On-Demand (Pay per request)
    • Enable server-side encryption for DynamoDB Table using AWS managed KMS Key
    • Creates a partition key called 'id' for DynamoDB Table
    • Retain the Table when deleting the CloudFormation stack
    • Enable continuous backups and point-in-time recovery

    AWS Lambda Function

    • Configure limited privilege access IAM role for Lambda function
    • Enable reusing connections with Keep-Alive for NodeJs Lambda function
    • Enable X-Ray Tracing
    • Enable Failure-Handling features like enable bisect on function Error, set defaults for Maximum Record Age (24 hours) & Maximum Retry Attempts (500) and deploy SQS dead-letter queue as destination on failure
    • Set Environment Variables
      • AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)

    Amazon Cognito

    • Set password policy for User Pools
    • Enforce the advanced security mode for User Pools

    Amazon Elasticsearch Service

    • Deploy best practices CloudWatch Alarms for the Elasticsearch Domain
    • Secure the Kibana dashboard access with Cognito User Pools
    • Enable server-side encryption for Elasticsearch Domain using AWS managed KMS Key
    • Enable node-to-node encryption for Elasticsearch Domain
    • Configure the cluster for the Amazon ES domain
