google_api_spanner v0.2.0 GoogleApi.Spanner.V1.Model.PlanNode View Source
Node information for nodes appearing in a QueryPlan.plan_nodes.
Attributes
- childLinks ([ChildLink]): List of child node `index`es and their relationship to this parent. Defaults to:
null
. - displayName (String.t): The display name for the node. Defaults to:
null
. - executionStats (%{optional(String.t) => String.t}): 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.t): 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 (%{optional(String.t) => String.t}): 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:
