Hazelcast Store

The Hazelcast EntityStore is a non-persistent EntityStore leveraging the Hazelcast in-memory data grid. It can be used when you need a large in-memory Store with high throughput.

The only thing needed to use the Hazelcast EntityStore, is to do the proper assembly in a module. We recommend the usage of the HazelcastEntityStoreAssembler which will add the service to the module.

Example

public static void main( String args )
{
   qi4j = new SingletonAssembler()
   {
       public void assemble( ModuleAssembly module )
           throws AssemblyException
       {
           Visibility vis = Visibility.module;
           new HazelcastEntityStoreAssembler( vis ).assemble( module );

           module.addEntities( ....
             :
             :
       }
   }.runtime();
}

Once a qi4j Application using the Hazelcast EntityStore is started, the default Hazelcast instances discovery
mechanism (multicast) is used. You can for example start Hazelcast nodes in other JVMs :

public static void main( String args )
{
HazelcastInstance h1 = Hazelcast.newHazelcastInstance(null);
}

This allows you to store more than what a single JVM process can allocate in a single EntityStore.
Plus, you can start multiple instances per JVM.
