Examples of LogicalPlan

org.apache.drill.common.logical.LogicalPlan
org.apache.pig.experimental.logical.relational.LogicalPlan
LogicalPlan is the logical view of relational operations Pig will execute for a given script. Note that it contains only relational operations. All expressions will be contained in LogicalExpressionPlans inside each relational operator.
org.apache.pig.impl.logicalLayer.LogicalPlan
org.apache.pig.newplan.logical.relational.LogicalPlan
LogicalPlan is the logical view of relational operations Pig will execute for a given script. Note that it contains only relational operations. All expressions will be contained in LogicalExpressionPlans inside each relational operator.
org.apache.tajo.engine.planner.LogicalPlan
This represents and keeps every information about a query plan for a query.
