@andycroll I just read your latest #onerubything email (great as always) but I noticed there’s a big “why not” that you didn’t mention. `find_each` doesn’t work reliably if your model has a UUID primary key, because `find_each` works by ordering everything by primary key and UUIDs aren’t sequential. Annoyingly rails doesn’t warn you about this (although if I get time I might raise a PR for that) so it’s possible for it to silently skip records if you use UUIDs.
