For a parallel Scan request, TotalSegments represents the total number of segments into which the Scan operation will
            be divided. The value of TotalSegments corresponds to the number of application workers that will perform the parallel scan. For
            example, if you want to scan a table using four application threads, you would specify a TotalSegments value of 4. The value for
            TotalSegments must be greater than or equal to 1, and less than or equal to 4096. If you specify a TotalSegments value of 1,
            the Scan will be sequential rather than parallel. If you specify TotalSegments, you must also specify Segment.
