@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface AWSStepFunctionsAsync extends AWSStepFunctions
AsyncHandler can be used to receive
notification when an asynchronous operation completes.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractAWSStepFunctionsAsync instead.
AWS Step Functions is a web service that enables you to coordinate the components of distributed applications and microservices using visual workflows. You build applications from individual components that each perform a discrete function, or task, allowing you to scale and change applications quickly. Step Functions provides a graphical console to visualize the components of your application as a series of steps. It automatically triggers and tracks each step, and retries when there are errors, so your application executes in order and as expected, every time. Step Functions logs the state of each step, so when things do go wrong, you can diagnose and debug problems quickly.
Step Functions manages the operations and underlying infrastructure for you to ensure your application is available at any scale. You can run tasks on the AWS cloud, on your own servers, or an any system that has access to AWS. Step Functions can be accessed and used with the Step Functions console, the AWS SDKs (included with your Beta release invitation email), or an HTTP API (the subject of this document).

Used by workers to retrieve a task (with the specified activity ARN) scheduled for execution by a running state
machine. This initiates a long poll, where the service holds the HTTP connection open and responds as soon as a
task becomes available (i.e. an execution of a task of this type is needed.) The maximum time the service holds
on to the request before responding is 60 seconds. If no task is available within 60 seconds, the poll will
return an empty result, that is, the taskToken returned is an empty string.
Workers should set their client side socket timeout to at least 65 seconds (5 seconds higher than the maximum time the service may hold the poll request).

Used by workers to report to the service that the task represented by the specified taskToken is
still making progress. This action resets the Heartbeat clock. The Heartbeat threshold
is specified in the state machine's Amazon States Language definition. This action does not in itself create an
event in the execution history. However, if the task times out, the execution history will contain an
ActivityTimedOut event.
The Timeout of a task, defined in the state machine's Amazon States Language definition, is its
maximum allowed duration, regardless of the number of SendTaskHeartbeat requests received.
This operation is only useful for long-lived tasks to report the liveliness of the task.
