love it! Thanks for the explainer. We were wringing our hands wondering if we should switch from zip to container based after getting close to the 256mb limit and fist fighting with layers. In the end we did and looks like it was a good choice.

So glad you enjoyed it! Definitely avoid using Lambda Layers (with a few exceptions). I did another video on this

Also I'd love to see a graph or some type of visualization on what percentage and specifically which parts of my code is already cached. I guess AWS would never do this

I agree, but mostly for the sake of curiosity. I'm not sure what actionable insight we'd get from that information, but it would be interesting!

I swing by proactively every now and then, as a preventative measure.
