-- Used by activity workers and task states using the
-- <https://docs.aws.amazon.com/step-functions/latest/dg/connect-to-resource.html#connect-wait-token callback>
-- pattern to report to Step Functions that the task represented by the
-- specified @taskToken@ is still making progress. This action resets the
-- @Heartbeat@ clock. The @Heartbeat@ threshold is specified in the state
-- machine\'s Amazon States Language definition (@HeartbeatSeconds@). This
-- action does not in itself create an event in the execution history.
-- However, if the task times out, the execution history contains an
-- @ActivityTimedOut@ entry for activities, or a @TaskTimedOut@ entry for
-- for tasks using the
-- <https://docs.aws.amazon.com/step-functions/latest/dg/connect-to-resource.html#connect-sync job run>
-- or
-- <https://docs.aws.amazon.com/step-functions/latest/dg/connect-to-resource.html#connect-wait-token callback>
-- pattern.
--
-- The @Timeout@ of a task, defined in the state machine\'s Amazon States
-- Language definition, is its maximum allowed duration, regardless of the
-- number of SendTaskHeartbeat requests received. Use @HeartbeatSeconds@ to
-- configure the timeout interval for heartbeats.
