Incremental Builds and Code Changes

[juanbiberretta]

Hello!

I'm trying to ascertain whether or not Gatsby is smart enough to only rebuild templates for whose code has changed. On Gatsby's documentation it says:

Which leads me to believe is the case, but from my local testing I cannot get it work. I have template A and template B, whenever I change something on template B (like adding a div or console.log), it rebuilds both template A and B. I'm persisting both public and .cache folder and I'm on the latest Gatsby version (3.5).

Am I just totally misunderstanding how that's supposed to work? Any help would be really appreciated!!
