Jihoon Son commented on TAJO-464:
---------------------------------
Thanks, Hyunsik. This is a definitely necessary work.
However, I'm wondering that 'shuffle' is the proper name in our query
execution. As you know, the name of 'shuffle' comes from a phase of
Hadoop/MapReduce that includes several processes such as sort and data
repartition.
Meanwhile, in our query execution, the intermediate data are just repartitioned
between the execution blocks.
So, in my opinion, 'repartition' is the more proper name than 'shuffle'.
I left some more comments at RB.
> Rename the name 'partition', actually meaning shuffle to 'shuffle'.

> So far, we have used the word 'partition' to indicate shuffle. This name was
> originated from repartition in the database studies. However, this name makes
> us hard to distinguish the shuffle and table partition. We ned to change such
> names and prefix into 'shuffle'.
