 With the 5.3 release, there is a brand new feature. I'm glad to announce that you will be able to use MongoDB as a cache store.

For those who don't know MongoDB, it's an open-source document oriented NoSQL database developped by 10Gen. You can more information about it on http://www.mongodb.org/.

The question you have right now, it probably, how to use it cool cache store ? Simple, as for the other cache store you have to add a loader in your Infinispan configuration file.

Here is an exemple:

 <loaders>
      <mongodbStore xmlns="urn:infinispan:config:mongodb:5.3" >
            <connection host="localhost" port="27017" timeout="2000" acknowledgment="0"/>
            <authentication username="mongoUser" password="mongoPass" />
            <storage database="infinispan_test_database" collection="infispan_cachestore" />
    </mongodbStore>
 </loaders>
ConfigurationBuilder b = new ConfigurationBuilder();
b.loaders().addStore(MongoDBCacheStoreConfigurationBuilder.class)
   .host( "localhost" )
   .port( 27017 )
   .timeout( 1500 )
   .acknowledgment( 0 )
   .username( "mongoDBUSer" )
   .password( "mongoBDPassword" )
   .database( "infinispan_cachestore" )
   .collection( "entries" );
 
final Configuration config = b.build();
MongoDBCacheStoreConfiguration store = (MongoDBCacheStoreConfiguration) config.loaders().cacheLoaders().get(0);
For more information about the configuration possibilities (default values, options, etc) , you can refer to the documentation page
