Node information for nodes appearing in a QueryPlan.plan_nodes.

Attributes

• childLinks (List[ChildLink]): List of child node `index`es and their relationship to this parent. Defaults to: null.
• displayName (String): The display name for the node. Defaults to: null.
• executionStats (Object): The execution statistics associated with the node, contained in a group of key-value pairs. Only present if the plan was returned as a result of a profile query. For example, number of executions, number of rows/time per execution etc. Defaults to: null.
• index (Integer): The `PlanNode`'s index in node list. Defaults to: null.

• kind (String): Used to determine the type of node. May be needed for visualizing different kinds of nodes differently. For example, If the node is a SCALAR node, it will have a condensed representation which can be used to directly embed a description of the node in its parent. Defaults to: null.

  • Enum - one of [KIND_UNSPECIFIED, RELATIONAL, SCALAR]
• metadata (Object): Attributes relevant to the node contained in a group of key-value pairs. For example, a Parameter Reference node could have the following information in its metadata: { "parameter_reference": "param1", "parameter_type": "array" } Defaults to: null.
• shortRepresentation (ShortRepresentation): Condensed representation for SCALAR nodes. Defaults to: null.
