Re-Design of Logical Plan
-------------------------
Key: PIG-73
URL: https://issues.apache.org/jira/browse/PIG-73
Project: Pig
Issue Type: Improvement
Components: impl
Reporter: Antonio Magnaghi
Assignee: Antonio Magnaghi
I am opening this new bug to track a specific work item within the broader
context of improving Pig support for optimizations.
See related items:
- PIG-50 in the jira
- the design spec at: http://wiki.apache.org/pig/PigExecutionModel
In particular we want to remove from the logical plan those aspects that
directly relate to the *execution* stage of a plan, hence improving decoupling.
Currently EvalSpecs and Conds (and relative pipes) are tightly coupled with
logical operators.
