Current approach

Proposed approach

Open discussion and tech discovery:

1. I've tried to implement the decorator pattern around caching and actual implementation. However, I think this might be a bit difficult and might introduce buggy behaviour when extending/replacing the core file fetching functionality. Therefore, I'm considering cache as a separate extendable/replaceable layer without interfering with the core logic of fetching from the file system.
2. The proposed approach allows source agnostic (i.e replacing file system with DB in a separate package for example)
