Drupal 7

Ming is an API for working with data in MongoDB. It was designed to allow rapid construction of MongoDB-based apps in Drupal, where Field integration is not required.

Ming is a wrapper around the PHP Mongo classes, which adds some additional capabilities and behaviours. In addition to what raw Mongo support provides, Ming has the following features:

• Preconfigure and connect to multiple persistent connections, from multiple Mongo database sources, using hooks, site variables, at runtime, or from the Mongodb module
• Simple wrappers around common Mongo tasks (Insert, Upsert, Delete, Find), including some common variants
• Shortcuts for accessing objects by MongoID, without the need to instantiate MongoID classes
• A scaffold class (ming\Ming\Item) for building, saving and working with MongoDB data

Ming does not require the Mongodb module to be installed, but will work with it.

This module integrates FuckItJS with your Drupal site.

A little crawler that helps to keep cached important pages.

This module stores fields both in MySQL and in MongDB. When loading entities, or querying them using EntityFieldQuery, it uses MongoDB. When using views, it uses MySQL.

Block Cache Stale is an answer to clear cache invalidation and regeneration.

Reverse Proxy Check is a simple module that adds a check to the Status Report to show whether or not the home page of your site is being served by a reverse proxy cache server for anonymous users.
