Reference documentation and code samples for the Cloud Spanner V1 API module Google::Cloud::Spanner::V1::PlanNode::Kind.
The kind of PlanNode. Distinguishes between the two different kinds of
nodes that can appear in a query plan.
Constants
KIND_UNSPECIFIED
value: 0 Not specified.
RELATIONAL
value: 1 Denotes a Relational operator node in the expression tree. Relational
operators represent iterative processing of rows during query execution.
For example, a TableScan operation that reads rows from a table.
SCALAR
value: 2 Denotes a Scalar node in the expression tree. Scalar nodes represent
non-iterable entities in the query plan. For example, constants or
arithmetic operators appearing inside predicate expressions or references
to column names.
