Drupal 8 offers major advances over Drupal 7 in many areas, including caching.
In Drupal 8, there are now two cache modules: Internal Page Cache and Internal Dynamic Page Cache. Do those two names sound confusingly similar? In that case, this blog post is for you.
In these three videos, Robert introduces us to how Drupal 8’s core caching systems work.
Drupal 8 core caching modules
- The Internal Page Cache module: this caches pages for anonymous users in the database. Pages requested by anonymous users are stored the first time they are requested and then are reused for future visitors.
- The Internal Dynamic Page Cache module: This is a key feature that Drupal 7 did not have. Unlike the Internal Page module, the Dynamic Page module aims to speed up the site for both anonymous and logged-in users. Wim Leers has a great overview of how and why the Dynamic Page module works.
