OptionalparentThe node this operation is executed within, or undefined for the root of the plan.
OptionalphysicalThe current physical query operator. This may be omitted if no physical operator applies.
OptionalrepeatedIf the operations executed within this node are repeated evaluations of the same operation, such as the per-binding evaluations of a bind join.
