type

Review comment:
We should avoid as much as possible utility functions in the recipes,
users should be able to copy/paste the recipe, only change the values to match
with their own variables/constants and have it work. So requiring users to
lookup for utilities that they need to embed in their code goes against the
principle of the Cookbook.
If those utilities really add value, they should just be implemented in
Arrow itself so that the cookbook and the users can rely on them.
