For parallel Scan requests, TotalSegmentsrepresents the total number of segments for a table that is being scanned. Segments are a way to logically divide a table into equally sized portions, for the duration of the Scan request. The value of TotalSegments corresponds to the number of application "workers" (such as threads or processes) 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.
