> 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. How about a runtime option (proposal updated to include this)? > 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 In theory the user could be feeding their own unaligned data completely unrelated to any Arrow component and so I'm not sure how to accomplish this. -- This is an automated message from the Apache Git Service.
