DrupalCon Vienna 2017: Rendering & caching: a journey through the layers

This talk explores the complexities of render technologies within Drupal, including Render API, Cache API, Dynamic Page Cache, Page Cache, and BigPipe. The speaker presents three practical use cases: an uncacheable block, a personalized block, and a cacheable block that updates based on entity changes. By examining these scenarios, the speaker illustrates how the different caching layers interact and how Drupal developers can leverage them effectively. Attendees will gain a deeper understanding of these technologies and strategies for testing their implementations. The speaker is a maintainer of Dynamic Page Cache and BigPipe, as well as a co-maintainer of Render API, Cache API, and Page Cache.
