segmentCount

For a parallel ListVectors request, segmentCount represents the total number of vector segments into which the ListVectors operation will be divided. The value of segmentCount corresponds to the number of application workers that will perform the parallel ListVectors operation. For example, if you want to use four application threads to list vectors in a vector index, specify a segmentCount value of 4.

If you specify a segmentCount value of 1, the ListVectors operation will be sequential rather than parallel.

If you specify segmentCount, you must also specify segmentIndex.
