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 (optionally) 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 does not in itself create an event in the workflow execution history. However, if the task times out, the workflow execution history will contain 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.
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. - You cannot use an IAM policy to constrain this action's parameters.
If the caller does not 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 will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

Creating a Request
recordActivityTaskHeartbeat Source #
Creates a value of RecordActivityTaskHeartbeat
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data RecordActivityTaskHeartbeat Source #
See: recordActivityTaskHeartbeat
smart constructor.
Request Lenses
rathDetails :: Lens' RecordActivityTaskHeartbeat (Maybe Text) Source #
If specified, contains details about the progress of the task.
rathTaskToken :: Lens' RecordActivityTaskHeartbeat Text Source #
The taskToken
of the ActivityTask.
taskToken
is generated by the service and should be treated as an opaque value. If the task is passed to another process, its taskToken
must also be passed. This enables it to provide its progress and respond with results.
Destructuring the Response
recordActivityTaskHeartbeatResponse Source #
Creates a value of RecordActivityTaskHeartbeatResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data RecordActivityTaskHeartbeatResponse Source #
Status information about an activity task.
See: recordActivityTaskHeartbeatResponse
smart constructor.
Response Lenses
rathrsResponseStatus :: Lens' RecordActivityTaskHeartbeatResponse Int Source #
The response status code.
rathrsCancelRequested :: Lens' RecordActivityTaskHeartbeatResponse Bool Source #
Set to true
if cancellation of the task is requested.
