taskPriority
If set, specifies the priority with which the activity task is to be assigned to a worker. This overrides the defaultTaskPriority specified when registering the activity type using RegisterActivityType. Valid values are integers that range from Java's Integer.MIN_VALUE
(-2147483648) to Integer.MAX_VALUE
(2147483647). Higher numbers indicate higher priority.
