   > Can you provide some performance changes and conclusions before and after 
the table conversion?
   1. Trigger bucket shuffle join for the following joins
   orders join lineitem
   part join partsupp
   
   2. The distribution num of lineitem equals to that of orders, so that the 
buckets of both table are aligned, and good for bucket shuffle.
