GoogleApi.Spanner.V1.Model.PlanNode (google_api_spanner v0.32.0) View Source

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 node indexes 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) - The PlanNode's index in node list.
  • kind (type: String.t, default: nil) - 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.
  • metadata (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" }
  • shortRepresentation (type: GoogleApi.Spanner.V1.Model.ShortRepresentation.t, default: nil) - Condensed representation for SCALAR nodes.
