heartbeatTimeout property
If set, specifies the maximum time before which a worker processing a task of this type must report progress by calling RecordActivityTaskHeartbeat. If the timeout is exceeded, the activity task is automatically timed out. If the worker subsequently attempts to record a heartbeat or returns a result, it is ignored. This overrides the default heartbeat timeout specified when registering the activity type using RegisterActivityType.
The duration is specified in seconds, an integer greater than or equal to
0. You can use NONE to specify unlimited duration.
Implementation
