Class HiveRowIsDeletedPropagator

java.lang.Object

org.apache.hadoop.hive.ql.optimizer.calcite.rules.views.HiveRowIsDeletedPropagator

All Implemented Interfaces:

org.apache.calcite.util.ReflectiveVisitor

public class HiveRowIsDeletedPropagator
extends Object
implements org.apache.calcite.util.ReflectiveVisitor

ReflectiveVisitor to propagate row is deleted or inserted columns to all HiveRelNodes' rowType in the plan. General rule: we expect that these columns are the last columns in the input rowType of the current HiveRelNode. This class is part of incremental rebuild of materialized view plan generation.
