Description of the need A website’s cache is only useful if it has the necessary content on hand to satisfy visitors’ requests. Pantheon’s granular cache control enables developers and site owners to manage updates to specific assets, pages, categories, and even personalization across our Global CDN.
Your sites will maintain a high cache hit rate (a.k.a. fast page load speeds) while ensuring the latest content is always in the hands of visitors. Pantheon’s granular cache control prevents inadvertently invalidating an entire site’s cache. There is no need to throw out an entire cache every time you make small content changes on a site.
Proposed solution Need to add backdrop CMS https://www.drupal.org/project/d8cache
