[> So how do we feel about:](https://github.com/apache/arrow/pull/35565#issuecomment-1552401874) This seems fine to me, with the caveat that always emitting a warning is inflexible for users who definitely want to avoid unaligned access. Perhaps they're building for a platform we're not aware of where unaligned access has more disastrous consequences than we've seen, or maybe they're just running with a sanitizer which detects unaligned access and emits an error even if the platform would allow the access. Therefore, I think that for the time being there should be a build option or at least an environment variable which such a user could set to ensure alignment. Also I think both the build option and the warning should be tagged with the number of an issue tracking (or, later: a link to documentation on) producers of unaligned data and how to mitigate that -- This is an automated message from the Apache Git Service.
