> PERFORMANCE: not creating bags for ORDER BY
> -------------------------------------------
>                 Key: PIG-802
>                 URL: https://issues.apache.org/jira/browse/PIG-802
>             Project: Pig
>          Issue Type: Improvement
>    Affects Versions: 0.2.0
>            Reporter: Olga Natkovich
>         Attachments: OrderByOptimization.patch
> Order by should be changed to not use POPackage to put all of the tuples in a 
> bag on the reduce side, as the bag is just immediately flattened. It can 
> instead work like join does for the last input in the join.
