Implements the App Engine memcache API.
Memcache caches database results and articles, reducing overall DB load and allowing seamless DB maintenance during quiet periods.
Used to cache most used files for our clients. Connected with CloudFlare Railgun Optimizer.
DVA: The Right Mix
As part of the cacheing system within Drupal.
Memcached mainly took care of creating and rebuilding the REST API cache once changes had been made within Drupal.
Memcached is used as a simple page cache across the whole application.
Shared object cache for sharded service backend.
Web Application Stack
Used as simple key-value cache store. To store query results etc.
Redis works just fine, we do not use this.
On the presentation tier, for caching of "display fragments".
Great for the server's performance.
