PlanCost

PlanCostBreakdown

Cardinality and unweighted logical work, plus the weighted scalar total.

PlannedVectorSearch

RelationalAccessCostContext

Immutable structural work for the row source of one relation.

RelationalAccessPathDescriptor

RelationalCsgCmpAlternative

RelationalCsgCmpEnumeration

RelationalCsgCmpJoinImplementation

A pre-bound implementation supported by the caller’s two-relation kernel. It competes inside memo selection, not after choosing a join order. Predicate IDs name the complete operator, including residual predicates.

RelationalJoinCostContexts

Per-binding row-source costs for one immutable join enumeration.

RelationalNestedLoopJoinCost

Conservative row-work estimate for an index nested-loop join.

RelationalOperatorCardinalityProfile

Estimated and observed output cardinality at one relational operator boundary.

RelationalOperatorId

Stable, plan-local identifier for a physical relational access or join operator.

estimate_relational_access_cost

estimate_relational_access_path_cost

Estimates logical work for a validated access descriptor.

estimate_relational_access_path_cost_with_context

Uses the same raw-component contract with relation-specific structural context. Row-root setup CPU and metadata access patterns retain separate raw components; cardinality and output stay independent. The final constructor weights every component once.

estimate_relational_join_cost

estimate_relational_join_cost_with_contexts

Extends join composition with the original row sources of its two inputs.

estimate_relational_nested_loop_join_cost

Estimates row visits for an index nested-loop join.

estimate_relational_probe_join_cost

Extends a left-deep plan with one probe join using the canonical relational cost model.

select_adaptive_vector_backend

select_relational_access_path

select_relational_access_path_with_context

Selects an access after context-aware skyline pruning. Candidate costs are comparable only when this context belongs to their common row source.

skyline_prune_relational_access_paths

Retains the Pareto frontier of relational access paths.

skyline_prune_relational_access_paths_with_context

Computes the frontier with the same immutable relation context used for final selection. The legacy entrypoint retains descriptor-only costs.

validate_vector_pipeline

visit_plan

visit_plan_with_ids

Visits a physical plan in pre-order and assigns each operator its plan-local identity.
