Drupal 7 and MongoDB as Pluggable Storage or Cache
NoSQL adoption.
“New Drupal 7 features such as the field API, pluggable storage and cache, enabled us to use Mongo as a “NoSQL” solution for high performance and scalability, while the new unit testing framework ensures a very stable core, even over several large core-merge efforts throughout the project. Examiner.com, with its high traffic volume and instant publishing capabilities, would have been very difficult or impossible to implement on earlier versions of Drupal.” said Jim Davidson, President, Examiner.com.
