canVectorize
public boolean canVectorize(Expr.InputBindingInspector inspector, List<Expr> args)
Description copied from interface:Function
Check if a function can be 'vectorized', for a given set ofExpr
inputs. If this method returns true,Function.asVectorProcessor(org.apache.druid.math.expr.Expr.VectorInputBindingInspector, java.util.List<org.apache.druid.math.expr.Expr>)
is expected to produce aExprVectorProcessor
which can evaluate values in batches to use with vectorized query engines.

asVectorProcessor
public <T> ExprVectorProcessor<T> asVectorProcessor(Expr.VectorInputBindingInspector inspector, List<Expr> args)
Description copied from interface:Function
Builds a 'vectorized' function expression processor, that can build vectorized processors for its input values usingExpr.asVectorProcessor(org.apache.druid.math.expr.Expr.VectorInputBindingInspector)
, for use in vectorized query engines.
