• [x] The first step here is to carefully document cache and cache_simple with our Diataxis approach.
  • [x] cache_simple
  • [x] cache
• [ ] Add the architecture info on the white paper
• [ ] Extract a blog from the documentation and publish

@gpsaggese Should i rewrite the documentation for cache, cache_simple ?

[gpsaggese]

What does "rewrite" mean?

We already have some docs

> ffind.py cache | grep md
./docs/tools/helpers/all.hcache_simple.explanation.md
./docs/tools/helpers/all.hcache.explanation.md

so we need to ensure they are current and see if we can improve them.

Let's focus on simple cache first.

I have made few improvements to ./docs/tools/helpers/all.hcache_simple.explanation.md, please have a look #862

@gpsaggese Directly copy-pasting documentation into a blog may feel a bit dry or documentation-heavy to external readers.

I’d like to propose lightly adapting the structure to fit a blog format — without changing the content itself. The goal is to preserve all technical accuracy, but present it with a more engaging tone.

For example:

• Add a 1-paragraph intro before the “Overview”
• "Why we built 'hcache_simple'?"(will cover the problem/motivation)
• Rewording some headers like Common Misunderstandings -> Gotchas to Watch out for

These small changes can make it more approachable and also being consistent with the documentation.

Or we can go ahead with copy-pasting for now, and later explore a structured approach to adapt the documentation for blog formats more efficiently.

I'm putting together some guidelines, but in few words we are trying to:

1. The blog and the doc are the same
2. It's optimized for consumption (e.g., bullet points, and no fluff)

@gpsaggese I have made changes to ./docs/tools/helpers/all.hcache.explanation.md, please review #868.

[]  Add the architecture info on the white paper

@gpsaggese Both hcache_simple and hcache docs include execution flow diagrams—do you think those sufficiently cover the architecture, or were you thinking of something more detailed or different?
