after you restart the fast load job,
Therefore, some number of rows will be sent to the AMPs
again because the restart starts on the next record after
the value stored in the checkpoint. Hence, when a restart
occurs, the first row after the checkpoint and some of the
consecutive rows are sent a second time. These will be
caught as duplicate rows after the sort. This restart logic
is the reason that FastLoad will not load duplicate rows
into a MULTISET table. It assumes they are duplicates
because of this logic.
