Node information for nodes appearing in a QueryPlan.plan_nodes.
Attributes
childLinks
(type:list(GoogleApi.Spanner.V1.Model.ChildLink.t)
, default:nil
) - List of child nodeindex
es and their relationship to this parent.displayName
(type:String.t
, default:nil
) - The display name for the node.executionStats
(type:map()
, default:nil
) - 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.index
(type:integer()
, default:nil

's index in node list.kind
(type:String.t
, default:nil

(type:map()
, default:nil
) - 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" }
