Registers a new activity type along with its configuration settings in the specified domain. Access Control

You can use IAM policies to control this action'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.
  • Constrain the following parameters by using a Condition element with the appropriate keys.
    • defaultTaskList.name: String constraint. The key is swf:defaultTaskList.name.
    • name: String constraint. The key is swf:name.
    • version: String constraint. The key is swf: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.

May throw TypeAlreadyExistsFault. May throw LimitExceededFault. May throw UnknownResourceFault. May throw OperationNotPermittedFault.

Parameter domain : The name of the domain in which this activity is to be registered.

Parameter name : The name of the activity type within the domain.

The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f). Also, it must not be the literal string arn.

Parameter version : The version of the activity type. The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f). Also, it must not be the literal string arn.

Parameter defaultTaskHeartbeatTimeout : If set, specifies the default maximum time before which a worker processing a task of this type must report progress by calling RecordActivityTaskHeartbeat. If the timeout is exceeded, the activity task is automatically timed out. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision. 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.

Parameter defaultTaskList : If set, specifies the default task list to use for scheduling tasks of this activity type. This default task list is used if a task list isn't provided when a task is scheduled through the ScheduleActivityTask Decision.

Parameter defaultTaskPriority : The default task priority to assign to the activity type. If not assigned, then 0 is used. 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 in the in the Amazon SWF Developer Guide..

Parameter defaultTaskScheduleToCloseTimeout : If set, specifies the default maximum duration for a task of this activity type. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Parameter defaultTaskScheduleToStartTimeout : If set, specifies the default maximum duration that a task of this activity type can wait before being assigned to a worker. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Parameter defaultTaskStartToCloseTimeout : If set, specifies the default maximum duration that a worker can take to process tasks of this activity type. This default can be overridden when scheduling an activity task using the ScheduleActivityTask Decision.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

Parameter description : A textual description of the activity type.
