GoogleApi.Spanner.V1.Model.PlanNode (google_api_spanner v0.48.0)
View SourceNode 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
) - ThePlanNode
'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.
