 ** defaultTaskHeartbeatTimeout **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskHeartbeatTimeout"></a>
 The default maximum time, in seconds, before which a worker processing a task must report progress by calling [RecordActivityTaskHeartbeat](API_RecordActivityTaskHeartbeat.md).  
You can specify this value only when *registering* an activity type. The registered default value can be overridden when you schedule a task through the `ScheduleActivityTask` [Decision](API_Decision.md). If the activity worker subsequently attempts to record a heartbeat or returns a result, the activity worker receives an `UnknownResource` fault. In this case, Amazon SWF no longer considers the activity task to be valid; the activity worker should clean up the activity task.  
The duration is specified in seconds, an integer greater than or equal to `0`. You can use `NONE` to specify unlimited duration.  
Type: String  
Length Constraints: Maximum length of 8.  
Required: No

 ** defaultTaskList **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskList"></a>
 The default task list specified for this activity type at registration. This default is used if a task list isn't provided when a task is scheduled through the `ScheduleActivityTask` [Decision](API_Decision.md). You can override the default registered task list when scheduling a task through the `ScheduleActivityTask` [Decision](API_Decision.md).  
Type: [TaskList](API_TaskList.md) object  
Required: No

 ** defaultTaskPriority **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskPriority"></a>
 The default task priority for tasks of this activity type, specified at registration. If not set, then `0` is used as the default priority. This default can be overridden when scheduling an activity task.  
Valid values are integers that range from Java's `Integer.MIN_VALUE` (-2147483648) to `Integer.MAX_VALUE` (2147483647). Higher numbers indicate higher priority.  
For more information about setting task priority, see [Setting Task Priority](https://docs.aws.amazon.com/amazonswf/latest/developerguide/programming-priority.html) in the *Amazon SWF Developer Guide*.  
Type: String  
Required: No

 ** defaultTaskScheduleToCloseTimeout **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskScheduleToCloseTimeout"></a>
 The default maximum duration, specified when registering the activity type, for tasks of this activity type. You can override this default when scheduling a task through the `ScheduleActivityTask` [Decision](API_Decision.md).  
The duration is specified in seconds, an integer greater than or equal to `0`. You can use `NONE` to specify unlimited duration.  
Type: String  
Length Constraints: Maximum length of 8.  
Required: No

 ** defaultTaskScheduleToStartTimeout **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskScheduleToStartTimeout"></a>
 The default maximum duration, specified when registering the activity type, that a task of an activity type can wait before being assigned to a worker. You can override this default when scheduling a task through the `ScheduleActivityTask` [Decision](API_Decision.md).  
The duration is specified in seconds, an integer greater than or equal to `0`. You can use `NONE` to specify unlimited duration.  
Type: String  
Length Constraints: Maximum length of 8.  
Required: No

 ** defaultTaskStartToCloseTimeout **   <a name="SWF-Type-ActivityTypeConfiguration-defaultTaskStartToCloseTimeout"></a>
 The default maximum duration for tasks of an activity type specified when registering the activity type. You can override this default when scheduling a task through the `ScheduleActivityTask` [Decision](API_Decision.md).  
The duration is specified in seconds, an integer greater than or equal to `0`. You can use `NONE` to specify unlimited duration.  
Type: String  
Length Constraints: Maximum length of 8.
