> I now recall why FLINK-3771 had a {{Translator}} interface with a {{translate}} method taking a field for reuse: when we translate edge ID the translator must be called twice.
> {{TranslateFunction}} will be modeled after {{MapFunction}} and {{RichTranslateFunction}} will be modeled after {{RichMapFunction}}.
> The unit test should have caught this but I was reusing values between fields which did not detect that values were overwritten.
