@Experimental(eta="2022-10-31")
public class ScalarArgument
extends Argument

This class represents the scalar argument passed to a Table Function.

This representation should be considered experimental. Eventually, ConnectorExpression should be extended to include this kind of argument.

Additionally, only constant values are currently supported. In the future, we will add support for different kinds of expressions.
