These are FalkorDB graph node properties, not the DuckDB column schema — and the counts are stale.Function below lists 8 properties and omits return_type, domain, num_params, annotated_args, _version, and _extracted_at. The “~18,420 nodes” figure is against ~59,000 actual.DuckDB is the primary analytical store, but its internal schema is outside this public reference.
