Why MultiLoad Utility supports only Non Unique Secondary
Index(NUSI) in the Target Table ?
Answer Posted / satish
When table is having NUSI, the sub table created by it will
be populated only by Hashing (not like Hash Re distribution
for USI), here redistribution of the records will not be
done,which will take more time generally,
As Fastload and Multiload are intended to Load the data at
fast they have taken out the USI, support so that the target
tables will be loaded very faster,
if we need we can create the SI after loading
