Thanks James, It is a good idea. The situation is that my customer will give different numbers of "in" conditions randomly. So sometimes there is 10 point lookups for a sql while sometimes there could be 100 thousand point lookups. If I change the guidepost width to a smaller digit , the parallelism number would be too many for the 10-point-lookup SQLs.
