ButterCMS and Gatsby Incremental Builds
Since v3, Gatsby supports incremental builds by default. It means that if your website is linked to ButterCMS and some content change, a full rebuild is no longer needed.
Full rebuilds, as the name suggests, rebuild whe whole website even if no change has been made to a particular section. Therefore, build times can get real long as your app grows in content.
In this experiment, the Home is not linked at all to Butter, but the blog is. If Post A changes, neither the Home nor Post B should change. That's the magic of incremental builds!
