Struct datafusion::logical_plan::plan::Filter
source · [−]pub struct Filter {
pub predicate: Expr,
pub input: Arc<LogicalPlan>,
}
Expand description
Filters rows from its input that do not match an expression (essentially a WHERE clause with a predicate expression).
Semantically, <predicate>
is evaluated for each row of the input;
If the value of <predicate>
is true, the input row is passed to
the output. If the value of <predicate>
is false, the row is
discarded.
Fields
predicate: Expr
The predicate expression, which must have Boolean type.
input: Arc<LogicalPlan>
The incoming logical plan
