        This AWS Solutions Construct implements an Amazon SQS queue connected to an AWS Lambda function.
        
        Here is a minimal deployable pattern definition in Typescipr:
        
        ```python
        # 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
        
        ```text
        new SqsToLambda(scope: Construct, id: string, props: SqsToLambdaProps);
        ```
        
        *Parameters*
        
        * scope [`Construct`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_core.Construct.html)
        * id `string`
        * props [`SqsToLambdaProps`](#pattern-construct-props)
        
        ## Pattern Construct Props
        
        | **Name**     | **Type**        | **Description** |
        |:-------------|:----------------|-----------------|
        |existingLambdaObj?|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error.|
        |lambdaFunctionProps?|[`lambda.FunctionProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.FunctionProps.html)|User provided props to override the default props for the Lambda function.|
        |existingQueueObj?|[`sqs.Queue`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sqs.Queue.html)|An optional, existing SQS queue to be used instead of the default queue. Providing both this and `queueProps` will cause an error.|
        |queueProps?|[`sqs.QueueProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sqs.QueueProps.html)|Optional user-provided props to override the default props for the SQS queue.|
        |deadLetterQueueProps?|[`sqs.QueueProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sqs.QueueProps.html)|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`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Returns an instance of the Lambda function created by the pattern.|
        |sqsQueue|[`sqs.Queue`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sqs.Queue.html)|Returns an instance of the SQS queue created by the pattern.|
        |deadLetterQueue?|[`sqs.Queue`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sqs.Queue.html)|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)
