org.apache.calcite.rel.convert.ConverterImpl

org.apache.hadoop.hive.ql.optimizer.calcite.reloperators.jdbc.HiveJdbcConverter

All Implemented Interfaces:

Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.convert.Converter, org.apache.calcite.rel.RelNode, HiveRelNode

public class HiveJdbcConverter
extends org.apache.calcite.rel.convert.ConverterImpl
implements HiveRelNode

This is a designated RelNode that splits the Hive operators and the Jdbc operators, every successor of this node will be Jdbc operator.
