>                 Key: PIG-211
>                 URL: https://issues.apache.org/jira/browse/PIG-211
>             Project: Pig
>          Issue Type: New Feature
>          Components: data
>            Reporter: John DeTreville
>            Priority: Minor
>
> Joining a table A with a small table B can be disproportionately expensive if 
> A must be sorted before the join, and the result must be sorted again. This 
> effort can often be reduced or eliminated if table B is replicated in whole 
> to all nodes.
