Package org.apache.hadoop.hive.ql.optimizer.calcite.rules.jdbc

JDBC external table rules that pushes down operators as much as possible to the external jdbc table.

Class Summary

Class	Description
JDBCAbstractSplitFilterRule	JDBCAbstractSplitFilterRule split a HiveFilter into two HiveFilter operators where the lower operator could be pushed down below the HiveJdbcConverter} operator and therefore could be sent to the external table.
JDBCAbstractSplitFilterRule.FilterSupportedFunctionsVisitor	FilterSupportedFunctionsVisitor traverse all of the Rex call and splits them into two lists, one with supported jdbc calls, and one with not supported jdbc calls.
JDBCAbstractSplitFilterRule.JDBCSplitFilterAboveJoinRule	JDBCSplitFilterAboveJoinRule split splitter above a HiveJoin operator, so we could push it into the HiveJoin.
JDBCAbstractSplitFilterRule.JDBCSplitFilterRule	JDBCSplitFilterRule splits a HiveFilter rule so we could push part of the HiveFilter into the jdbc.
JDBCAggregationPushDownRule	JDBCAggregationPushDownRule convert a HiveAggregate into a org.apache.calcite.adapter.jdbc.JdbcRules.JdbcAggregateRule.JdbcAggregate and pushes it down below the HiveJdbcConverter operator so it will be sent to the external table.
JDBCExtractJoinFilterRule	JDBCExtractJoinFilterRule extracts out the HiveFilter from a HiveJoin operator.
JDBCFilterJoinRule	Rule that tries to push filter expressions into a join condition and into the inputs of the join.
JDBCFilterPushDownRule	JDBCExtractJoinFilterRule extracts out the HiveFilter from a HiveJoin operator.
JDBCJoinPushDownRule	JDBCJoinPushDownRule convert a HiveJoin into a JdbcRules.JdbcJoin and pushes it down below the HiveJdbcConverter} operator so it will be sent to the external table.
JDBCProjectPushDownRule	JDBCProjectPushDownRule convert a HiveProject into a org.apache.calcite.adapter.jdbc.JdbcRules.JdbcAggregateRule.JdbcProject and pushes it down below the HiveJdbcConverter} operator so it will be sent to the external table.
JDBCRexCallValidator	A utility class that helps identify Hive-Jdbc functions gaps.
JDBCSortPushDownRule	JDBCSortPushDownRule convert a HiveSortLimit into a JdbcRules.JdbcSort and pushes it down below the HiveJdbcConverter} operator so it will be sent to the external table.
JDBCUnionPushDownRule	JDBCUnionPushDownRule convert a HiveUnion into a JdbcRules.JdbcUnion and pushes it down below the HiveJdbcConverter} operator so it will be sent to the external table.
