Uses of Rule in io.prestosql.sql.planner.iterative.rule

Classes in io.prestosql.sql.planner.iterative.rule that implement Rule

Modifier and Type	Class and Description
class	AddIntermediateAggregations Adds INTERMEDIATE aggregations between an un-grouped FINAL aggregation and its preceding PARTIAL aggregation.
class	CreatePartialTopN
class	DetermineJoinDistributionType
class	DetermineSemiJoinDistributionType This rule must run after the distribution type has already been set for delete queries, since semi joins in delete queries must be replicated.
class	EliminateCrossJoins
class	EvaluateZeroSample Replaces 0% sample node with empty values node.
static class	ExtractSpatialJoins.ExtractSpatialInnerJoin
static class	ExtractSpatialJoins.ExtractSpatialLeftJoin
static class	GatherAndMergeWindows.MergeAdjacentWindowsOverProjects
static class	GatherAndMergeWindows.SwapAdjacentWindowsBySpecifications
class	ImplementBernoulliSampleAsFilter Transforms:
class	ImplementFilteredAggregations Implements filtered aggregations by transforming plans of the following shape:
class	ImplementOffset Transforms:
class	InlineProjections Inlines expressions from a child project node into a parent project node as long as they are simple constants, or they are referenced only once (to avoid introducing duplicate computation) and the references don't appear within a TRY block (to avoid changing semantics).
class	MergeFilters
class	MergeLimitOverProjectWithSort Transforms:
class	MergeLimits
class	MergeLimitWithDistinct
class	MergeLimitWithSort
class	MergeLimitWithTopN
class	MultipleDistinctAggregationToMarkDistinct Implements distinct aggregations with different inputs by transforming plans of the following shape:
class	ProjectOffPushDownRule<N extends PlanNode>
class	PruneAggregationColumns
class	PruneAggregationSourceColumns
class	PruneCountAggregationOverScalar A count over a subquery can be reduced to a VALUES(1) provided the subquery is a scalar
class	PruneCrossJoinColumns Cross joins don't support output symbol selection, so push the project-off through the node.
class	PruneFilterColumns
class	PruneIndexSourceColumns
class	PruneJoinChildrenColumns Non-Cross joins support output symbol selection, so make any project-off of child columns explicit in project nodes.
class	PruneJoinColumns Non-cross joins support output symbol selection, so absorb any project-off into the node.
class	PruneLimitColumns
class	PruneMarkDistinctColumns
class	PruneOrderByInAggregation
class	PruneOutputColumns
class	PruneProjectColumns
class	PruneSemiJoinColumns
class	PruneSemiJoinFilteringSourceColumns
class	PruneTableScanColumns
class	PruneTopNColumns
class	PruneValuesColumns
class	PruneWindowColumns
class	PushAggregationThroughOuterJoin This optimizer pushes aggregations below outer joins when: the aggregation is on top of the outer join, it groups by all columns in the outer table, and the outer rows are guaranteed to be distinct.
class	PushLimitIntoTableScan
class	PushLimitThroughMarkDistinct
class	PushLimitThroughOffset Transforms:
class	PushLimitThroughOuterJoin Transforms:
class	PushLimitThroughProject
class	PushLimitThroughSemiJoin
class	PushLimitThroughUnion Transforms:
class	PushOffsetThroughProject Transforms:
class	PushPartialAggregationThroughExchange
class	PushPartialAggregationThroughJoin
class	PushPredicateIntoTableScan These rules should not be run after AddExchanges so as not to overwrite the TableLayout chosen by AddExchanges
class	PushProjectionThroughExchange Transforms:
class	PushProjectionThroughUnion
class	PushRemoteExchangeThroughAssignUniqueId Pushes RemoteExchange node down through the AssignUniqueId to preserve partitioned_on(unique) and grouped(unique) properties for the output of the AssignUniqueId.
class	PushSampleIntoTableScan
class	PushTableWriteThroughUnion
class	PushTopNThroughOuterJoin Transforms:
class	PushTopNThroughProject Transforms:
class	PushTopNThroughUnion
class	RemoveAggregationInSemiJoin Remove the aggregation node that produces distinct rows from the Filtering source of a Semi join.
class	RemoveEmptyDelete If the predicate for a delete is optimized to false, the target table scan of the delete will be replaced with an empty values node.
class	RemoveFullSample Removes 100% sample nodes.
class	RemoveRedundantDistinctLimit Replace DistinctLimit node 1.
class	RemoveRedundantIdentityProjections Removes projection nodes that only perform non-renaming identity projections
class	RemoveRedundantLimit Remove Limit node when the subplan is guaranteed to produce fewer rows than the limit and replace the plan with empty values if the limit count is 0.
class	RemoveRedundantSort
class	RemoveRedundantTopN Replace TopN node 1.
class	RemoveTrivialFilters
class	RemoveUnreferencedScalarApplyNodes
class	RemoveUnreferencedScalarLateralNodes
class	ReorderJoins
class	RewriteSpatialPartitioningAggregation Re-writes spatial_partitioning(geometry) aggregations into spatial_partitioning(envelope, partition_count) on top of ST_Envelope(geometry) projection, e.g.
class	SimplifyCountOverConstant
class	SingleDistinctAggregationToGroupBy Implements distinct aggregations with similar inputs by transforming plans of the following shape:
class	TransformCorrelatedInPredicateToJoin Replaces correlated ApplyNode with InPredicate expression with SemiJoin
class	TransformCorrelatedLateralJoinToJoin Tries to decorrelate subquery and rewrite it using normal join.
class	TransformCorrelatedScalarAggregationToJoin Scalar aggregation is aggregation with GROUP BY 'a constant' (or empty GROUP BY).
class	TransformCorrelatedScalarSubquery Scalar filter scan query is something like:
class	TransformCorrelatedSingleRowSubqueryToProject This optimizer can rewrite correlated single row subquery to projection in a way described here: From:
class	TransformExistsApplyToLateralNode EXISTS is modeled as (if correlated predicates are equality comparisons):
class	TransformUncorrelatedInPredicateSubqueryToSemiJoin This optimizers looks for InPredicate expressions in ApplyNodes and replaces the nodes with SemiJoin nodes.
class	TransformUncorrelatedLateralToJoin
