This AWS Solutions Construct implements an Amazon SQS queue connected to an AWS Lambda function.
Here is a minimal deployable pattern definition in Typescipr:
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from aws_solutions_constructs.aws_sqs_lambda import SqsToLambda, SqsToLambdaProps
SqsToLambda(self, "SqsToLambdaPattern",
lambda_function_props=FunctionProps(
runtime=lambda_.Runtime.NODEJS_10_X,
handler="index.handler",
code=lambda_.Code.from_asset(f"{__dirname}/lambda")
)
)
Initializer
new SqsToLambda(scope: Construct, id: string, props: SqsToLambdaProps);
Parameters
- scope
Construct
- id
string
- props
SqsToLambdaProps
Pattern Construct Props
Name | Type | Description |
---|---|---|
existingLambdaObj? | lambda.Function |
Existing instance of Lambda Function object, if this is set then the lambdaFunctionProps is ignored. |
lambdaFunctionProps? | lambda.FunctionProps |
User provided props to override the default props for the Lambda function. |
existingQueueObj? | sqs.Queue |
An optional, existing SQS queue to be used instead of the default queue. If an existing queue is provided, the queueProps property will be ignored. |
queueProps? | sqs.QueueProps |
Optional user-provided props to override the default props for the SQS queue. |
deadLetterQueueProps? | sqs.QueueProps |
Optional user-provided props to override the default props for the dead letter SQS queue. |
deployDeadLetterQueue? | boolean |
Whether to create a secondary queue to be used as a dead letter queue. Defaults to true. |
maxReceiveCount? | number |
The number of times a message can be unsuccessfully dequeued before being moved to the dead letter queue. Defaults to 15. |
Pattern Properties
Name | Type | Description |
---|---|---|
lambdaFunction | lambda.Function |
Returns an instance of the Lambda function created by the pattern. |
sqsQueue | sqs.Queue |
Returns an instance of the SQS queue created by the pattern. |
deadLetterQueue? | sqs.Queue |
Returns an instance of the dead-letter SQS queue created by the pattern. |
Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
Amazon SQS Queue
- Deploy SQS dead-letter queue for the source SQS Queue
- Enable server-side encryption for source SQS Queue using AWS Managed KMS Key
- Enforce encryption of data in transit
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
-
Set Environment Variables
- AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
