Parameter
Name	Description
`other`	`PlanNode`

Properties

ChildLinks

public RepeatedField<PlanNode.Types.ChildLink> ChildLinks { get; }

List of child node indexes and their relationship to this parent.

Property Value
Type	Description
`Google.Protobuf.Collections.RepeatedField<PlanNode.Types.ChildLink>`

DisplayName

public string DisplayName { get; set; }

The display name for the node.

Property Value
Type	Description
`String`

ExecutionStats

public Struct ExecutionStats { get; set; }

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.

Property Value
Type	Description
`Google.Protobuf.WellKnownTypes.Struct`

Index

public int Index { get; set; }

The PlanNode's index in [node list][google.spanner.v1.QueryPlan.plan_nodes].

Property Value
Type	Description
`Int32`

Kind

public PlanNode.Types.Kind Kind { get; set; }

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][google.spanner.v1.PlanNode.Kind.SCALAR] node, it will have a condensed representation which can be used to directly embed a description of the node in its parent.

Property Value
Type	Description
`PlanNode.Types.Kind`

Metadata

public Struct Metadata { get; set; }

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" }

Property Value
Type	Description
`Google.Protobuf.WellKnownTypes.Struct`

ShortRepresentation

public PlanNode.Types.ShortRepresentation ShortRepresentation { get; set; }

Condensed representation for [SCALAR][google.spanner.v1.PlanNode.Kind.SCALAR] nodes.

Property Value
Type	Description
`PlanNode.Types.ShortRepresentation`
