Overview

This class provides a default implementation for set(), when your resource does not benefit from batching. Instead of processing changes yourself, the ‘create`, `update`, and `delete` functions, are called for you, with proper logging already set up. Note that your type needs to use `ensure` in the conventional way to signal presence and absence of resources.
