Used by workers to get an ActivityTask from the specified activity `taskList`.

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.

Records a `WorkflowExecutionCancelRequested` event in the currently running workflow execution identified by the given domain, workflowId, and runId. This logically requests the cancellation of the workflow execution as a whole. It is up to the decider to take appropriate actions when it receives an execution history with this event.

If the runId isn't specified, the `WorkflowExecutionCancelRequested` event is recorded in the history of the current open workflow execution with the specified workflowId in the domain.

Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.

Access Control

Only use this operation if the `canceled` flag of a RecordActivityTaskHeartbeat request returns `true` and if the activity can be safely undone or abandoned.

A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out.

- `CancelWorkflowExecution` – Closes the workflow execution and records a `WorkflowExecutionCanceled` event in the history.

- `CompleteWorkflowExecution` – Closes the workflow execution and records a `WorkflowExecutionCompleted` event in the history .

- `ContinueAsNewWorkflowExecution` – Closes the workflow execution and starts a new workflow execution of the same type using the same workflow ID and a unique run Id. A `WorkflowExecutionContinuedAsNew` event is recorded in the history.

- `FailWorkflowExecution` – Closes the workflow execution and records a `WorkflowExecutionFailed` event in the history.

- `RecordMarker` – Records a `MarkerRecorded` event in the history. Markers can be used for adding custom information in the history for instance to let deciders know that they don't need to look at the history beyond the marker event.

- `RequestCancelActivityTask` – Attempts to cancel a previously scheduled activity task. If the activity task was scheduled but has not been assigned to a worker, then it is canceled. If the activity task was already assigned to a worker, then the worker is informed that cancellation has been requested in the response to RecordActivityTaskHeartbeat.

- `RequestCancelExternalWorkflowExecution` – Requests that a request be made to cancel the specified external workflow execution and records a `RequestCancelExternalWorkflowExecutionInitiated` event in the history.

- `ScheduleActivityTask` – Schedules an activity task.

- `SignalExternalWorkflowExecution` – Requests a signal to be delivered to the specified external workflow execution and records a `SignalExternalWorkflowExecutionInitiated` event in the history.

- `StartChildWorkflowExecution` – Requests that a child workflow execution be started and records a `StartChildWorkflowExecutionInitiated` event in the history. The child workflow execution is a separate workflow execution with its own history.

- `StartTimer` – Starts a timer for this workflow execution and records a `TimerStarted` event in the history. This timer fires after the specified delay and record a `TimerFired` event.

Access Control

If you grant permission to use `RespondDecisionTaskCompleted`, you can use IAM policies to express permissions for the list of decisions returned by this action as if they were members of the API. Treating decisions as a pseudo API maintains a uniform conceptual model and helps keep policies readable. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

Decision Failure

Decisions can fail for several reasons

- The ordering of decisions should follow a logical flow. Some decisions might not make sense in the current context of the workflow execution and therefore fails.

- A limit on your account was reached.

- The decision lacks sufficient permissions.

One of the following events might be added to the history to indicate an error. The event attribute's `cause` parameter indicates the cause. If `cause` is set to `OPERATION_NOT_PERMITTED`, the decision failed because it lacked sufficient permissions. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

- `ScheduleActivityTaskFailed` – A `ScheduleActivityTask` decision failed. This could happen if the activity type specified in the decision isn't registered, is in a deprecated state, or the decision isn't properly configured.

- `RequestCancelActivityTaskFailed` – A `RequestCancelActivityTask` decision failed. This could happen if there is no open activity task with the specified activityId.

- `StartTimerFailed` – A `StartTimer` decision failed. This could happen if there is another open timer with the same timerId.

- `CancelTimerFailed` – A `CancelTimer` decision failed. This could happen if there is no open timer with the specified timerId.

- `StartChildWorkflowExecutionFailed` – A `StartChildWorkflowExecution` decision failed. This could happen if the workflow type specified isn't registered, is deprecated, or the decision isn't properly configured.

- `SignalExternalWorkflowExecutionFailed` – A `SignalExternalWorkflowExecution` decision failed. This could happen if the `workflowID` specified in the decision was incorrect.

- `RequestCancelExternalWorkflowExecutionFailed` – A `RequestCancelExternalWorkflowExecution` decision failed. This could happen if the `workflowID` specified in the decision was incorrect.

- `CancelWorkflowExecutionFailed` – A `CancelWorkflowExecution` decision failed. This could happen if there is an unhandled decision task pending in the workflow execution.

- `CompleteWorkflowExecutionFailed` – A `CompleteWorkflowExecution` decision failed. This could happen if there is an unhandled decision task pending in the workflow execution.

- `ContinueAsNewWorkflowExecutionFailed` – A `ContinueAsNewWorkflowExecution` decision failed. This could happen if there is an unhandled decision task pending in the workflow execution or the ContinueAsNewWorkflowExecution decision was not configured correctly.

- `FailWorkflowExecutionFailed` – A `FailWorkflowExecution` decision failed. This could happen if there is an unhandled decision task pending in the workflow execution.

The preceding error events might occur due to an error in the decider logic, which might put the workflow execution in an unstable state The cause field in the event structure for the error event indicates the cause of the error.

A workflow execution may be closed by the decider by returning one of the following decisions when completing a decision task: `CompleteWorkflowExecution`, `FailWorkflowExecution`, `CancelWorkflowExecution` and `ContinueAsNewWorkflowExecution`. An `UnhandledDecision` fault is returned if a workflow closing decision is specified and a signal or activity event had been added to the history while the decision task was being performed by the decider. Unlike the above situations which are logic issues, this fault is always possible because of race conditions in a distributed system. The right action here is to call RespondDecisionTaskCompleted without any decisions. This would result in another decision task with these new events included in the history. The decider should handle the new events and may decide to close the workflow execution.

Access Control

You can use IAM policies to control this decision's access to Amazon SWF resources as follows:

- Use a `Resource` element with the domain name to limit the action to only specified domains.

- Use an `Action` element to allow or deny permission to call this action.

- You cannot use an IAM policy to constrain this action's parameters.

If the caller doesn't have sufficient permissions to 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 and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

Access Control

You can use IAM policies to control this decision's access to Amazon SWF resources as follows:

- Use a `Resource` element with the domain name to limit the action to only specified domains.

- Use an `Action` element to allow or deny permission to call this action.

- You cannot use an IAM policy to constrain this action's parameters.

If the caller doesn't have sufficient permissions to 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`.

- Use a `Resource` element with the domain name to limit the action to only specified domains.

- Use an `Action` element to allow or deny permission to call this action.

- Constrain the following parameters by using a `Condition` element with the appropriate keys.

  - `tagList.member.N` – The key is \"swf:tagList.N\" where N is the tag number from 0 to 4, inclusive.

  - `taskList` – String constraint. The key is `swf:taskList.name`.

  - `workflowType.name` – String constraint. The key is `swf:workflowType.name`.

  - `workflowType.version` – String constraint. The key is `swf:workflowType.version`.

If the caller doesn't have sufficient permissions to 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 and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

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.
