> That is true. I guess the question is if `arrow`'s OutputStream API makes an explicit _guarantee_ that `Open` should throw if the target does not exist. My guess would be that you shouldn't built code upon this assumption if it isn't explicitly stated in `arrow`'s API/docs (which it is not), but of course real-world usage deviates from that (Hyrum's Law). The API docs generally do not go into that level of detail. However, it is a general assumption that a filesystem "looks like" a local filesystem API-wise. It is also much more convenient to get an error early, than after you have already "written" multiple megabytes of data to the file. A compromise would be to add a dedicated option in `S3Options`, but of course the optimization would only benefit those users that enable the option. -- This is an automated message from the Apache Git Service.
