With Luminary’s 21 years of experience in the digital space, my experience of 17 years in the CMS space as well as our focus on Headless since 2016, here are my two cents on what you should look out for. From a developer perspective, not only static assets need to be cached on a CDN. Look out for: Caching of images and content via CDN.

The general idea is to cache and replay results, saving repeated executions of inner-side operators wherever possible. When a spool is able to replay cached results, this is known as a rewind. You may find it helpful to think of a spool rebind as a cache miss, and a rewind as a cache hit. Lazy Table Spool.
