类 PlanFinalizer

java.lang.Object

org.apache.flink.optimizer.traversals.PlanFinalizer

所有已实现的接口:

org.apache.flink.util.Visitor<PlanNode>

public class PlanFinalizer
extends Object
implements org.apache.flink.util.Visitor<PlanNode>

This visitor traverses the selected execution plan and finalizes it:

• The graph of nodes is double-linked (links from child to parent are inserted).
• If unions join static and dynamic paths, the cache is marked as a memory consumer.
• Relative memory fractions are assigned to all nodes.
• All nodes are collected into a set.
