Subject [jira] Commented: (PIG-158) Rework logical plan
Date Wed, 16 Apr 2008 12:43:21 GMT

    [ https://issues.apache.org/jira/browse/PIG-158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589536#action_12589536

Pi Song commented on PIG-158:
-----------------------------

Santhosh,

These are questions, no more comments:-

1. Are you going to use the nested plan concept? If so, we would need nested plan in these
operators: LOSort (SortColPlans), LOFilter (ConditionPlan), LOSplit (ConditionPlans), LOForEach
(EvaluationPlans), LOCogroup (GroupByPlans).

2. In a nested plan, what kind of operators can be root nodes?  I guess POProject is one of
them?
