        public PartitionRestrictionProgressChecker()
        Indicates how many mode transitions have been completed for the current mode. The transitions are as follows: * (1) UPDATE_STATE, (2) QUERY_CHANGE_STREAM, (3) WAIT_FOR_CHILD_PARTITIONS, (4) DONE.

        This is used to calculate the units of work left, meaning that 1 transition = 1 unit of work.
