> The cast function implementation to go from varchar to int/bigint is
> relatively large and every time we use this function, we add this logic to
> our run time generated class and JVM has to optimize the same logic multiple
> times. Instead it would be useful to have a utility method that contains the
> casting logic, which will be called in the runtime generated code that the
> JVM will need to optimize only once.
