//
// This is the AWS Lambda API Reference. The AWS Lambda Developer Guide provides
// additional information. For the service overview, go to What is AWS Lambda
// (http://docs.aws.amazon.com/lambda/latest/dg/welcome.html), and for information
// about how the service works, go to AWS Lambda: How it Works (http://docs.aws.amazon.com/lambda/latest/dg/lambda-introduction.html)
// in the AWS Lambda Developer Guide.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.

//     // Create a Lambda client with additional configuration
