> 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.
