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.
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][google.spanner.v1.PlanNode.Kind.SCALAR] node, it will have a condensed representation
which can be used to directly embed a description of the node in its
parent.
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:
