Instance Attribute Details
#child_links ⇒ Array<Google::Apis::SpannerV1::ChildLink>
List of child node index
es and their relationship to this parent.
Corresponds to the JSON property childLinks

#display_name ⇒ String
The display name for the node.
Corresponds to the JSON property displayName

#execution_stats ⇒ Hash<String,Object>
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.
Corresponds to the JSON property executionStats

# File 'generated/google/apis/spanner_v1/classes.rb', line 1936 def execution_stats @execution_stats end |
#index ⇒ Fixnum
The PlanNode
's index in node list.
Corresponds to the JSON property index

# File 'generated/google/apis/spanner_v1/classes.rb', line 1941 def index @index end |
#kind ⇒ 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.
Corresponds to the JSON property kind

#metadata ⇒ Hash<String,Object>
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"
Corresponds to the JSON property metadata

#short_representation ⇒ Google::Apis::SpannerV1::ShortRepresentation
Condensed representation of a node and its subtree. Only present for
SCALAR
PlanNode(s).
Corresponds to the JSON property shortRepresentation
