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

Namespace

Google \ Cloud \ Spanner \ V1

Methods

__construct

Constructor.

Parameters
Name	Description
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<PlanNode\ChildLink> List of child node indexes and their relationship to this parent.
↳ short_representation	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.
