PERFORMANCE: more extensive use of the combier
----------------------------------------------
Key: PIG-479
URL: https://issues.apache.org/jira/browse/PIG-479
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
On types branch, the combiner is used anytime a foreach includes only simple
projections and/or algebraic functions. It would also be useful to invoke the
combiner in cases where algebraic and non-algebraic operations are mixed, or
where expression evaluation is included in the foreach.
