--------------------------------------
Summary: Improve performance of POPartialAgg
Key: PIG-2888
URL: https://issues.apache.org/jira/browse/PIG-2888
Project: Pig
Issue Type: Improvement
Reporter: Dmitriy V. Ryaboy
During performance testing, we found that POPartialAgg can cause performance
degradation for Pig jobs when the Algebraic UDFs it's being applied to aren't
well suited to the operator's assumptions. Changing the implementation to a
more flexible hash-based model can provide significant performance improvements.
