I think my confusion comes from the fact that PK means unique and not null and that having null in any column in the tuple we upsert by, means that tuple matches nothing from the SQL perspective. It feels easier to assume columns we use in equality deletes are not nullable. I agree about the downside of not being able to use optional columns added later but I am not sure how important that is. We can probably cover that use case with default values that LinkedIn is working on. -- This is an automated message from the Apache Git Service.
