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.

Only present if the child node is
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.
