Modules

activation_fusion

ActivationFusionRule — fuses adjacent GraphActivationExec nodes into one.

depth_scheduling

DepthSchedulingRule — prunes physical plan operators based on query complexity.

namespace_partition_prune

NamespacePartitionPruneRule — simplifies IN predicates to equality for single namespace.

policy_pushdown

PolicyPushdownRule — injects namespace filter predicates into physical plans.

prospective_short_circuit

ProspectiveShortCircuitExec — execution operator for logical ProspectiveSearch.

temporal_index

TemporalIndexRule — pushes temporal range filters down to leverage Lance BTree indices.

Functions

all_rules

Returns all hirn physical optimizer rules.
