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 IAMto Manage Access to Amazon SWF Workflows.

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.

The fields accessible through corresponding lenses are:

rathrCancelRequested :: Lens' RecordActivityTaskHeartbeatResponse Bool Source
Set to true
if cancellation of the task is requested.
