org.apache.hadoop.hive.ql.optimizer.calcite.HiveCalciteUtil.JoinLeafPredicateInfo

Enclosing class:

HiveCalciteUtil

public static class HiveCalciteUtil.JoinLeafPredicateInfo
extends Object

JoinLeafPredicateInfo represents leaf predicate in Join condition (conjuctive lement).

JoinLeafPredicateInfo:
1. Stores list of expressions from left and right child which is part of equi join keys.
2. Stores set of projection indexes from left and right child which is part of equi join keys; the indexes are both in child and Join node schema.
