Zend_Cache_Backend_MongoDb

Notes:

• do not attempt to use MongoDb as a cache store with a capped collection
  • see: http://www.mongodb.org/display/DOCS/Capped+Collections#CappedCollections-UsageandRestrictions
• Requires mongodb version >= 2.0

Create the collection and indexes

var database_name = "zend_cache";
var collection = "etags";

use database_name;
db.createCollection(collection);
db.getCollection(collection).ensureIndex({"tags" : true});
db.getCollection(collection).ensureIndex({"expire" : true});
db.getCollection(collection).ensureIndex({"mtime" : true});
db.getCollection(collection).getIndexes();

Class Instantiation:

<?php
$frontendOptions = array(
    'lifetime' => 7200, 
    'automatic_serialization' => true
);
$backendOptions = array(
    'database_name' => 'zend_cache',
    'collection'    => 'cache'
);
$cache = Zend_Cache::factory('Core', 'MongoDb', $frontendOptions, $backendOptions);
$cache->save($data, $id, array('tag1','acct_id:1234');
$data = $cache->load($id);

With example methods:

<?php
$cache = new Zend_Cache_Backend_MongoDb(
    array('database_name' => 'zend_cache',
    'database_urn' => 'mongodb://localhost:27717'
    'collection' => 'cache')
);
$cache->getTags();
$cache->getIds();
$cache->getIdsMatchingAnyTags();
$cache->getIdsMatchingTags(array('tag1','tag2'));
$cache->getIdsNotMatchingTags(array('tag1','tag2'));
$cache->getMetadatas($id);
