Module partition 

Declarative partition validation, value comparison, and routing semantics.

Structs

PartitionContext

Traits

PartitionCatalog

Hierarchy definitions needed to validate and route a row; no storage writes are exposed.

PartitionExpressions

Evaluate declared partition keys and bounds with the caller’s expression scope.

Functions

partition_constraint_accepts_document

Evaluate a retained detached-partition CHECK without requiring a live parent edge. This is also the exact predicate used for prospective ATTACH row scans.

partition_hierarchy_root

partition_identity_owner

Return the physical counter owner for legacy auto-increment metadata. Declarative partitions share the top partitioned parent’s counter; newly created SERIAL and identity columns use their durable sequence binding instead.

partition_insert_target

prospective_partition_bound_accepts_document

Test one stored row against a prospective direct-child bound before the hierarchy edge is installed. DEFAULT means no existing non-default sibling accepts the row, matching the routing decision the new edge will expose.

validate_hash_partition_spec

validate_new_partition_bound
