How to reduce skew factor on stage tables with NoPI? - response (2) by jodba

Hi VM,
 
These are probably small tables tables loaded with batch load TD utility.
Even though it is true that your NoPI tables will be loaded in round robin manner in this case, the round robin is applied on block level (not row level).
This implies that in the case of small tables that fit in one (a couple) of blocks, all the data will end up on a single (a couple) of AMPs. That should explain the high skew factor.
 
I would recommend distributing those tables on appropriate PI column.
You won't get any benefits on FastLoading a small NoPI table.
 
Cheers,
Igor
