> 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.
