When restoring/copying a No Primary Index (NoPI) table to a destination system that has a different number of AMPs than the source system, there is a high probability that the data will be skewed on the destination system after the restore/copy. This is due to the algorithm that is used by the DBS to distribute the data rows onto the AMPs for a NoPI table.
