Description

Would be great with a guide (building on the CI with Cachix guide) that shows how to speed up CI, like minimizing rebuilds, making tests be derivations, and reducing cache fetching. This thread sparked some discussion.

Research direction

Start by reading the existing CI with Cachix guide and the linked discussion thread. Define the guide around minimizing rebuilds, making tests derivations, and reducing cache fetching; it is done when those CI-speedup techniques are clearly explained in a new guide.
