PHP 7 is not supported by the legacy 'mongo' extension and I currently have no plans to update this to use the new 'mongodb' extension which is not API compatible. I will happily accept a pull rquest though! :)
This Magento extension is primarily two things:
An abstraction layer for MongoDb. Like the MySQL abstraction layer included in Magento, it provides
classes that extend Mage_Core_Model_Abstract and Varien_Data_Collection. It also includes support for
.js upgrade scripts, an indexer to automatically index fields in other collections, and a schema
defined by XML files.
An atomic job queue. The job queue can be run by the Magento cron or by a separate script and supports future execution dates, automatic retry intervals, disabling jobs by name or group name, and priorities.
See mongo.xml.sample and Job.php for more information.
Cm_Mongo can be used with EcomDev_PhpUnit, but needs to override one of it's classes for fixtures with mongo collections to work. Add a module dependency on EcomDev_PhpUnit to Cm_Mongo.xml when using with EcomDev_PhpUnit.
