Metadata associated with a parent-child relationship appearing in a [PlanNode][google.spanner.v1.PlanNode].

Value parameters

childIndex: 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.

Condensed representation of a node and its subtree. Only present for SCALAR [PlanNode(s)][google.spanner.v1.PlanNode].

Value parameters

description: A string representation of the expression subtree rooted at this node.
subqueries: A mapping of (subquery variable name) -> (subquery node id) for cases where the description string of this node references a SCALAR subquery contained in the expression subtree rooted at this node. The referenced SCALAR subquery may not necessarily be a direct child of this node.
