[jira] [Created] (PIG-3764) Compile physical operators to bytecode

Julien Le Dem created PIG-3764:
----------------------------------

             Summary: Compile physical operators to bytecode
                 Key: PIG-3764
                 URL: https://issues.apache.org/jira/browse/PIG-3764
             Project: Pig
          Issue Type: Improvement
          Components: impl
            Reporter: Julien Le Dem


I started a prototype here:
https://github.com/julienledem/pig/compare/trunk...compile_physical_plan

The current physical plan is relatively inefficient at evaluating expressions.
In the context of a better execution engine (Tez, Spark, ...), compiling expressions to bytecode would be a significant speedup.
