Github user cloud-fan commented on the issue: https://github.com/apache/spark/pull/21192 I don't see the necessity of having an order here. We can do the array option interface, or this one first. Using format like `x0a 0d` is acceptable here, while it seems better to use array option. From engineering point of view, we should try out best to avoid dependencies between different works. If you think `x0a 0d` is a bad format, then it's fair to block this PR and we can discuss what's wrong with it.
