Typescript	@aws-solutions-constructs/aws-iot-sqs
Java	software.amazon.awsconstructs.services.iotsqs

This AWS Solutions Construct implements an AWS IoT MQTT topic rule and an AWS SQS Queue pattern.

Here is a minimal deployable pattern definition in Typescript:

const { IotToSqsProps, IotToSqs } from '@aws-solutions-constructs/aws-iot-sqs';

const props: IotToSqsProps = {
    iotTopicRuleProps: {
        topicRulePayload: {
            ruleDisabled: false,
            description: "Testing the IotToSqs Pattern",
            sql: "SELECT * FROM 'iot/sqs/#'",
            actions: []
        }
    }
};

new IotToSqs(this, 'test-iot-sqs-integration', props);

Initializer

new IotToSqs(scope: Construct, id: string, props: IotToSqsProps);

Parameters

• scope Construct
• id string
• props IotToSqsProps

Pattern Construct Props

Name	Type	Description
existingQueueObj?	sqs.Queue	Existing instance of SQS queue object, providing both this and queueProps will cause an error.
queueProps?	sqs.QueueProps	User provided props to override the default props for the SQS queue.
deadLetterQueueProps?	sqs.QueueProps	Optional user provided properties for the dead letter queue.
deployDeadLetterQueue?	boolean	Whether to deploy a secondary queue to be used as a dead letter queue. Default true.
maxReceiveCount?	number	The number of times a message can be unsuccessfully dequeued before being moved to the dead-letter queue. Required field if deployDeadLetterQueue=true.
enableEncryptionWithCustomerManagedKey?	boolean	Use a KMS Key, either managed by this CDK app, or imported. If importing an encryption key, it must be specified in the encryptionKey property for this construct.
encryptionKey?	kms.Key	An optional, imported encryption key to encrypt the SQS queue.
encryptionKeyProps?	kms.KeyProps	Optional user-provided props to override the default props for the encryption key.
iotTopicRuleProps?	iot.CfnTopicRuleProps	User provided CfnTopicRuleProps to override the defaults

Pattern Properties

Name	Type	Description
encryptionKey?	kms.Key	Returns an instance of kms.Key used for the SQS queue.
iotActionsRole	iam.Role	Returns an instance of iam.Role created by the construct, which allows IoT to publish messages to the SQS Queue
sqsQueue	sqs.Queue	Returns an instance of sqs.Queue created by the construct
deadLetterQueue?	sqs.Queue	Returns an instance of the dead-letter SQS queue created by the pattern.
iotTopicRule	iot.CfnTopicRule	Returns an instance of iot.CfnTopicRule created by the construct

Default settings

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

Amazon IoT Rule

• Configure an IoT Rule to send messages to the SQS Queue

Amazon IAM Role

• Configure least privilege access IAM role for Amazon IoT to be able to publish messages to the SQS Queue

Amazon SQS Queue

• Deploy a dead-letter queue for the source queue.
• Enable server-side encryption for the source queue using a customer-managed AWS KMS key.
• Enforce encryption of data in transit.
