> The common pattern for application level caching

  data = cache.get('stuff')
  if data is None:
      data = list(Stuff.objects.all())
      cache.set('stuff', data)
  return data

I'm wondering if you simplified the example or if you are just not preventing cache regen race conditions ?

Some other frameworks just put back the expired data for a few seconds while the new one is being regenerated to avoid having multiple workers building the same thing.

e.g. rails: https://github.com/rails/rails/blob/3182295ce2fa01b02cb9af0b...
