[−][src]Struct google_spanner1::PlanNode
Node information for nodes appearing in a QueryPlan.plan_nodes.
This type is not used in any activity, and only used as part of another schema.
Fields
index: Option<i32>
The PlanNode
's index in node list.
kind: Option<String>
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: Option<String>
The display name for the node.
execution_stats: Option<HashMap<String, String>>
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.
child_links: Option<Vec<ChildLink>>
List of child node index
es and their relationship to this parent.
short_representation: Option<ShortRepresentation>
Condensed representation for SCALAR nodes.
metadata: Option<HashMap<String, String>>
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"
}````
