        child_index:
            The node to which the link points.
        type:
            The type of the link. For example, in Hash Joins this could be
            used to distinguish between the build child and the probe
            child, or in the case of the child being an output variable,
            to represent the tag associated with the output variable.
        variable:
            Only present if the child node is
            [SCALAR][google.spanner.v1.PlanNode.Kind.SCALAR] and
            corresponds to an output variable of the parent node. The
            field carries the name of the output variable. For example, a
            ``TableScan`` operator that reads rows from a table will have
            child links to the ``SCALAR`` nodes representing the output
            variables created for each column that is read by the
            operator. The corresponding ``variable`` fields will be set to
            the variable names assigned to the columns.

          The ``PlanNode``'s index in [node

      kind:
          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.
      display_name:
          The display name for the node.
      child_links:
          List of child node ``index``\ es and their relationship to
          this parent.
      short_representation:
          Condensed representation for
          [SCALAR][google.spanner.v1.PlanNode.Kind.SCALAR] nodes.
      metadata:
          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:
          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.
