Olga Natkovich resolved PIG-211.

Resolution: Fixed

This has been implemented in the latest code. See PigLatin manual for details
Replicating small tables for joins

Key: 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.
