RE: Which partition we have to use for Aggregate Stage in parallel jobs ?
 
Its  always preferable & appropriate that we must use a sort stage beore aggregate stage.
Hence based on the aggregate logic we should sort the incoming data by using hash partintion on keys.

Then we can use same partition on Aggregate stage.

This is most commonly used.
