describe-activity-type

Description

Returns information about the specified activity type. This includes configuration settings provided when the type was registered and other general information about the type.

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.
    • activityType.name : String constraint. The key is swf:activityType.name .
    • activityType.version : String constraint. The key is swf:activityType.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 .

Synopsis

  describe-activity-type
--domain <value>
--activity-type <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--domain (string)

The name of the domain in which the activity type is registered.

--activity-type (structure)

The activity type to get information about. Activity types are identified by the name and version that were supplied when the activity was registered.

Shorthand Syntax:

name=string,version=string

JSON Syntax:

{
  "name": "string",
  "version": "string"
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

typeInfo -> (structure)

General information about the activity type.

The status of activity type (returned in the ActivityTypeInfo structure) can be one of the following.

  • REGISTERED – The type is registered and available. Workers supporting this type should be running.
  • DEPRECATED – The type was deprecated using deprecate-activity-type , but is still in use. You should keep workers supporting this type running. You cannot create new tasks of this type.

activityType -> (structure)

The activity-type type structure representing the activity type.

name -> (string)

The name of this activity.

Note

The combination of activity type name and version must be unique within a domain.

version -> (string)

The version of this activity.

Note

The combination of activity type name and version must be unique with in a domain.

status -> (string)

The current status of the activity type.

description -> (string)

The description of the activity type provided in register-activity-type .

creationDate -> (timestamp)

The date and time this activity type was created through register-activity-type .

deprecationDate -> (timestamp)

If DEPRECATED, the date and time deprecate-activity-type was called.

configuration -> (structure)

The configuration settings registered with the activity type.

defaultTaskStartToCloseTimeout -> (string)

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 .

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

defaultTaskHeartbeatTimeout -> (string)

The default maximum time, in seconds, before which a worker processing a task must report progress by calling record-activity-task-heartbeat .

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 . 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.

defaultTaskList -> (structure)

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 . You can override the default registered task list when scheduling a task through the ScheduleActivityTask Decision .

name -> (string)

The name of the task list.

defaultTaskPriority -> (string)

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 in the Amazon SWF Developer Guide .

defaultTaskScheduleToStartTimeout -> (string)

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 .

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

defaultTaskScheduleToCloseTimeout -> (string)

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 .

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