| Class | Description |
|---|---|
| CombineFilterRule |
A simple rule that combines two nested filter plans and combines them into a single filter plan with a conjunction
of the two filters.
|
| FilterWithConjunctNestedToNestingContextRule |
A rule that looks for a logical filter that contains a conjunction that includes a non-repeated nested predicate
(
NestedField) and transforms the inner expression to a version with respect to the NestedContext
defined by that nested field. |
| FilterWithNestedToNestingContextRule |
A rule that looks for a logical filter that contains a non-repeated nested predicate (
NestedField) and
transforms the inner expression to a version with respect to the NestedContext defined by that nested field. |
| FilterWithOneOfThemToNestingContextRule |
A rule that looks for a logical filter that contains a repeated nested predicate
(
OneOfThemWithComponent) and transforms the inner expression
to a version with respect to the NestedContext defined by that nested field. |
| FindIndexForComponentWithComparisonRule |
A rewrite rule that turns a logical filter on the results of a full scan (without a sort) into an index scan on
a compatibly ordered index.
|
| FindPossibleIndexForAndComponentRule |
A rule that finds all indexes that could implement one of the
ComponentWithComparison conjuncts of an AND
filter, leaving all the other filters (of any type, including other fields) as a residual filter. |
| FlattenNestedAndComponentRule |
A simple rule that performs some basic Boolean normalization by flattening a nested
AndComponent into a single,
wider AND. |
| FullUnorderedExpressionToScanPlanRule |
A rule for implementing a
FullUnorderedScanExpression as a RecordQueryScanPlan of the full primary
key space. |
| ImplementDistinctRule |
A rule that implements a distinct expression by adding a
RecordQueryUnorderedPrimaryKeyDistinctPlan
if necessary. |
| ImplementFilterRule |
A rule that implements a logical filter around a
RecordQueryPlan as a RecordQueryFilterPlan. |
| ImplementTypeFilterRule |
A rule that implements a logical type filter on an (already implemented)
RecordQueryPlan as a
RecordQueryTypeFilterPlan. |
| ImplementUnorderedUnionRule |
A rule that implements an unordered union of its (already implemented) children.
|
| LogicalToPhysicalScanRule |
A rule that converts a logical index scan expression to a
RecordQueryIndexPlan. |
| OrToUnorderedUnionRule |
Convert a filter on an or expression into a plan on the union.
|
| PushComponentWithComparisonIntoExistingScanRule |
A simple rule that looks for a
ComponentWithComparison
predicate and a compatibly ordered index scan comparison down to the index scan. |
| PushConjunctComponentWithComparisonIntoExistingScanRule |
A rule that selects one of the
ComponentWithComparison
conjuncts from an AND and tries to push it into an existing logical scan. |
| PushDistinctFilterBelowFilterRule |
A rule that moves a
RecordQueryUnorderedPrimaryKeyDistinctPlan
below a RecordQueryFilterPlan. |
| PushTypeFilterBelowFilterRule |
A rule that moves a
RecordQueryTypeFilterPlan below a RecordQueryFilterPlan. |
| RemoveNestedContextRule |
A rule that finds a
RelationalPlannerExpression inside of a NestedContextExpression and produces the
unnested equivalent planner expression. |
| RemoveRedundantTypeFilterRule |
A rule that eliminates logical type filters that are completely redundant; that is, when the child of the logical
type filter is guaranteed to return records of types included in the filter.
|
| SortToIndexRule |
A rule for implementing a
LogicalSortExpression as a scan of an appropriately-ordered index. |
