Class Summary

Class	Description
HiveAggregateIncrementalRewritingRuleBase<T extends HiveAggregateIncrementalRewritingRuleBase.IncrementalComputePlan>	This class implements the main algorithm of rewriting an MV maintenance plan to incremental.
HiveAggregateIncrementalRewritingRuleBase.IncrementalComputePlan
HiveAggregateInsertDeleteIncrementalRewritingRule	This rule will perform a rewriting to prepare the plan for incremental view maintenance in case there exist aggregation operator, so we can avoid the INSERT OVERWRITE and use a MERGE statement instead.
HiveAggregateInsertIncrementalRewritingRule	This rule will perform a rewriting to prepare the plan for incremental view maintenance in case there exist aggregation operator, so we can avoid the INSERT OVERWRITE and use a MERGE statement instead.
HiveAggregatePartitionIncrementalRewritingRule	Rule to prepare the plan for incremental view maintenance if the view is partitioned and insert only: Insert overwrite the partitions which are affected since the last rebuild only and leave the rest of the partitions intact.
HiveAugmentMaterializationRule	This rule will rewrite the materialized view with information about its invalidation data.
HiveInsertOnlyScanWriteIdRule	This rule turns on populating writeId of insert only table scans.
HiveJoinInsertDeleteIncrementalRewritingRule	This rule will perform a rewriting to prepare the plan for incremental view maintenance in case there is no aggregation operator but some of the source tables has delete operations, so we can avoid the INSERT OVERWRITE and use a MULTI INSERT statement instead: one insert branch for inserted rows and another for inserting deleted rows to delete delta.
HiveJoinInsertDeleteIncrementalRewritingRule.FilterPropagator
HiveJoinInsertIncrementalRewritingRule	This rule will perform a rewriting to prepare the plan for incremental view maintenance in case there is no aggregation operator, so we can avoid the INSERT OVERWRITE and use a INSERT statement instead.
HiveMaterializationRelMetadataProvider	Metadata provider implementation that is only used for MV rewriting.
HiveMaterializedViewBoxing	This class contains logic that is useful to trigger additional materialized view rewritings.
HiveMaterializedViewBoxing.Box
HiveMaterializedViewRule	Enable join and aggregate materialized view rewriting
HiveMaterializedViewRule.HiveMaterializedViewOnlyAggregateRule
HiveMaterializedViewRule.HiveMaterializedViewProjectAggregateRule
HiveMaterializedViewUtils
HiveRowIsDeletedPropagator	HiveRelShuttle to propagate rowIsDeleted column to all HiveRelNodes' rowType in the plan.
MaterializedViewIncrementalRewritingRelVisitor	This class is a helper to check whether a materialized view rebuild can be transformed from INSERT OVERWRITE to INSERT INTO.
