Container for the parameters to the RecordActivityTaskHeartbeat operation.
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 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 doesn't in itself create an event in the workflow execution history. However,
if the task times out, the workflow execution history contains 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 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.
