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 \ V1Methods
__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ index
↳ 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
↳ short_representation
↳ 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.
