Functions

entity_graph_provider

Try to get the entity-graph provider from a [CatalogManager] weak reference. Returns None when the manager is not the kv-backed one or the provider has not been injected yet (the computed graph tables then stream empty).

information_extension

Try to get the [InformationExtension] from [CatalogManager] weak reference.

inspect_plan 🔒

Builds a datanode inspection plan with the requested output schema.

inspect_request 🔒

System table predicates are inexact: the frontend keeps a residual filter. Dropping an unsafe remote filter preserves correctness only if no remote limit truncates it.

projected_schema 🔒

Projects an inspection table schema according to the scan request.

table_meta_manager

Try to get the [TableMetadataManagerRef] from [CatalogManager] weak reference.
