BindingAssignerOptimizer |
Assigns values to variables based on a supplied set of bindings.
|
BindingSetAssignmentInlinerOptimizer |
|
CompareOptimizer |
A query optimizer that replaces Compare operators with SameTerm s, if possible.
|
ConjunctiveConstraintSplitterOptimizer |
Splits conjunctive constraints into seperate constraints.
|
ConstantOptimizer |
A query optimizer that optimizes constant value expressions.
|
DisjunctiveConstraintOptimizer |
A query optimizer that optimize disjunctive constraints on tuple expressions.
|
FilterOptimizer |
Optimizes a query model by pushing Filter s as far down in the model tree as possible.
|
IterativeEvaluationOptimizer |
|
OrderLimitOptimizer |
Moves the Order node above the Projection when variables are projected.
|
ParentReferenceChecker |
|
ParentReferenceCleaner |
Cleans up QueryModelNode.getParentNode() references that have become inconsistent with the actual algebra
tree structure due to optimization operations.
|
ProjectionRemovalOptimizer |
If a projection node in the algebra does not contribute or change the results it can be removed from the tree.
|
QueryJoinOptimizer |
A query optimizer that re-orders nested Joins.
|
QueryModelNormalizerOptimizer |
A query optimizer that (partially) normalizes query models to a canonical form.
|
RegexAsStringFunctionOptimizer |
A query optimizer that replaces REGEX with FunctionCall s that are equivalent operators
|
SameTermFilterOptimizer |
A query optimizer that embeds Filter s with SameTerm operators in statement patterns as much as
possible.
|
StandardQueryOptimizerPipeline |
|
UnionScopeChangeOptimizer |
Inspect Union clauses to check if scope change can be avoided (allowing injection of pre-bound vars into union
arguments).
