Olga Natkovich commented on PIG-73:
-----------------------------------
Alan, can this be cloased? The execution pipeline rework consumes this, right?
> 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

> 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.
