I am looking for a modern Content Management Framework that is build from scratch on something different than SQL databases.
I have been operating large sites with millions of nodes on Drupal. A lot of the functionality was moved to Solr and NoSQL storage all kind of caches added... Drupal does its job, but a lot of data was stored redundantly.
Drupals' Entity API can solve a lot of the requirements, but the whole CMS still is built around the SQL idea.
I have found Rubedo, based on MongoDB that has unfortunately been discontinued.
Are there any modern CMS frameworks that are built on something different than SQL from scratch and can be used for larger projects?
