URL: https://github.com/apache/beam/pull/15327#issuecomment-898002838
> If you want to do a larger refactor (and intelliJ should make this easy),
you can rename getValues() -> getRawValues()
I could be convinced to do that in a follow up :P
I chose to use a simple for loop to avoid some intermediate object
allocations w/ IntStream, Collect, etc, since this is a pretty hot-path method.

> RowCoderGenerator.encodeDelegate calls getValue for each field on a row
> twice, one to check if it is null in scanNullFields, and one to actually get
> the value to be encoded.
> If getValue is expensive (for example, it has to recursively adapt a type to
> a beam Row), this causes unneeded extra work.
> Instead we could call value.getValues to get all values once, then pass them
> to scanNullFields and re-use them when encoding the values.
