Stability: Experimental

This is a developer preview (public beta) module.

All classes are under active development and subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.


Language Package
Python Logo Python aws_solutions_konstruk.aws_iot_lambda_dynamodb
Typescript Logo Typescript @aws-solutions-konstruk/aws-iot-lambda-dynamodb

This AWS Solutions Konstruk implements an AWS IoT topic rule, an AWS Lambda function and Amazon DynamoDB table with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { IotToLambdaToDynamoDBProps,  IotToLambdaToDynamoDB } = require('@aws-solutions-konstruk/aws-iot-lambda-dynamodb');

const props: IotToLambdaToDynamoDBProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler'
    },
    iotTopicRuleProps: {
        topicRulePayload: {
            ruleDisabled: false,
            description: "Processing of DTC messages from the AWS Connected Vehicle Solution.",
            sql: "SELECT * FROM 'connectedcar/dtc/#'",
            actions: []
        }
    }
};

new IotToLambdaToDynamoDB(stack, 'test-iot-lambda-dynamodb-stack', props);

Initializer

new IotToLambdaToDynamoDB(scope: Construct, id: string, props: IotToLambdaToDynamoDBProps);

Parameters

Pattern Construct Props

Name Type Description
deployLambda boolean Whether to create a new Lambda function or use an existing Lambda function. If set to false, you must provide an existing function for the existingLambdaObj property.
existingLambdaObj? lambda.Function An optional, existing Lambda function. This property is required if deployLambda is set to false.
lambdaFunctionProps lambda.FunctionProps Optional user provided props to override the default props for lambda.Function
iotTopicRuleProps iot.CfnTopicRuleProps User provided props to override the default props
dynamoTableProps? dynamodb.TableProps Optional user provided props to override the default props for DynamoDB Table

Pattern Properties

Name Type Description
iotTopicRule() iot.CfnTopicRule Retruns an instance of iot.CfnTopicRule created by the construct
lambdaFunction() lambda.Function Retruns an instance of lambda.Function created by the construct
dynamoTable() dynamodb.Table Retruns an instance of dynamodb.Table created by the construct
