"""
The following are some code snippets on how i optimized a system using Dogpile cache into native Redis, while still leveraging dogpile.

This is not fully functional code, it's just snippets to explain and help the next person:

General Overview:

* The cached data is a computed value of multiple permissions for an A2B relation.
* The Redis key is `'calculated-a|%s' % id_a`. 
* The payload is stored in a field, via `id_b`.

This test harness showcases an odd scenario when providing compatibility
