Daniel Dai updated PIG-3764:
----------------------------
Description:
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.
This is a candidate project for Google summer of code 2014. More information
about the program can be found at
https://cwiki.apache.org/confluence/display/PIG/GSoc2014
