/**
* Client for accessing AWS SFN. All service calls made using this client are blocking, and will not return until the
* service call completes.
*
* AWS Step Functions
*
* AWS Step Functions is a service that lets you coordinate the components of distributed applications and microservices
* using visual workflows.
*
*
* You can use Step Functions to build applications from individual components, each of which performs a discrete
* function, or task, allowing you to scale and change applications quickly. Step Functions provides a console
* that helps visualize the components of your application as a series of steps. Step Functions automatically triggers
* and tracks each step, and retries steps when there are errors, so your application executes predictably and in the
* right order every time. Step Functions logs the state of each step, so you can quickly diagnose and debug any issues.
*
*
* Step Functions manages operations and underlying infrastructure to ensure your application is available at any scale.
* You can run tasks on AWS, your own servers, or any system that has access to AWS. You can access and use Step
* Functions using the console, the AWS SDKs, or an HTTP API. For more information about Step Functions, see the AWS Step Functions Developer Guide .
