Cloud Spanner V1 Client - Class PlanNode (1.57.0)

Reference documentation and code samples for the Cloud Spanner V1 Client class PlanNode.

Node information for nodes appearing in a QueryPlan.plan_nodes.

Generated from protobuf message google.spanner.v1.PlanNode

Methods

__construct

Constructor.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ index int

The PlanNode's index in node list.

↳ kind int

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.

↳ display_name string

The display name for the node.

↳ child_links array<Google\Cloud\Spanner\V1\PlanNode\ChildLink>

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

↳ short_representation Google\Cloud\Spanner\V1\PlanNode\ShortRepresentation

Condensed representation for SCALAR nodes.

↳ metadata Google\Protobuf\Struct

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" }

↳ execution_stats Google\Protobuf\Struct

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.

The PlanNode's index in node list.
