%% @doc Amazon Simple Workflow Service
%%
%% The Amazon Simple Workflow Service (Amazon SWF) makes it easy to build
%% applications that use Amazon's cloud to coordinate work across
%% distributed components.
%%
%% In Amazon SWF, a task represents a logical unit of work that is performed
%% by a component of your workflow. Coordinating tasks in a workflow involves
%% managing intertask dependencies, scheduling, and concurrency in accordance
%% with the logical flow of the application.
%%
%% Amazon SWF gives you full control over implementing tasks and coordinating
%% them without worrying about underlying complexities such as tracking their
%% progress and maintaining their state.
%%
%% This documentation serves as reference only. For a broader overview of the
%% Amazon SWF programming model, see the Amazon SWF Developer Guide .

%%
%% Deciders should set their client side socket timeout to at least 70

%%
%% Because the number of workflow history events for a single workflow

%% @doc Used by activity workers to report to the service that the
%% `ActivityTask' represented by the specified `taskToken' is still
%% making progress.
%%
%% The worker can also specify details of the progress, for example percent
%% complete, using the `details' parameter. This action can also be used
%% by the worker as a mechanism to check if cancellation is being requested
%% for the activity task. If a cancellation is being attempted for the
%% specified task, then the boolean `cancelRequested' flag returned by
%% the service is set to `true'.
%%
%% This action resets the `taskHeartbeatTimeout' clock. The
%% `taskHeartbeatTimeout' is specified in `RegisterActivityType'.
%%
%% This action doesn't in itself create an event in the workflow
%% execution history. However, if the task times out, the workflow execution
%% history contains a `ActivityTaskTimedOut' event that contains the
%% information from the last heartbeat generated by the activity worker.
%%
%% The `taskStartToCloseTimeout' of an activity type is the maximum
%% duration of an activity task, regardless of the number of
%% `RecordActivityTaskHeartbeat' requests received. The
%% `taskStartToCloseTimeout' is also specified in
%% `RegisterActivityType'.
%%
%% This operation is only useful for long-lived activities to report
%% liveliness of the task and to determine if a cancellation is being
%% attempted.
%%
%% If the `cancelRequested' flag returns `true', a cancellation is
%% being attempted. If the worker can cancel the activity, it should respond
%% with `RespondActivityTaskCanceled'. Otherwise, it should ignore the
%% cancellation request.

%% @doc Records a `WorkflowExecutionTerminated' event and forces closure
%% of the workflow execution identified by the given domain, runId, and
%% workflowId.
%%
%% The child policy, registered with the workflow type or specified when
%% starting this execution, is applied to any open child workflow executions
%% of this workflow execution.
%%
%% If the identified workflow execution was in progress, it is terminated
%% immediately.
%%
%% If a runId isn't specified, then the `WorkflowExecutionTerminated'
%% event is recorded in the history of the current open workflow with the
%% matching workflowId in the domain.
%%
%% You should consider using `RequestCancelWorkflowExecution' action
%% instead because it allows the workflow to gracefully close while
%% `TerminateWorkflowExecution' doesn't.

%%
%% </li> <li> Use an `Action' element to allow or deny permission to call
%% this action.

%% </li> <li> You cannot use an IAM policy to constrain this action's
%% parameters.

%% invoke the action, or the parameter values fall outside the specified
%% constraints, the action fails. The associated event attribute's
%% `cause' parameter is set to `OPERATION_NOT_PERMITTED'. For details
