Replicating small tables for joins
----------------------------------
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.
