   > I understand that you are using the dummy "chunk" column to be able to 
have a partitioned dataset without having a natural column to partition on, but 
my feeling is that this is a bit of a workaround because we don't give a better 
alternative (yet).

   > Personally, I would maybe use a more useful partitioning column as the 
main example, and then mention the "chunk" column as a way to do it if there is 
no column already present that can be used for partitioning (and then we can 
easily update this when a better API becomes available)
   
   Switched to a real column (`year` of birthday) instead of using the chunk 
column.
