8.4.4.4. Configure the Replicated Data Grid

JBoss Data Grid's replicated mode ensures that every entry is replicated on every node in the data grid.
This mode offers security against data loss due to node failures and excellent data availability. These benefits are at the cost of limiting the storage capacity to the amount of storage available on the node with the least memory.
Programmatic Configuration:

Use the following code snippet to programmatically configure the cache for replication mode (either synchronous or asynchronous): 

private static EmbeddedCacheManager createCacheManagerProgramatically() {
   return new DefaultCacheManager(
      new GlobalConfigurationBuilder()
         .transport().addProperty("configurationFile", "jgroups.xml")
         .build(),
      new ConfigurationBuilder()
         .clustering().cacheMode(CacheMode.REPL_SYNC)
         .build()
   );
}

Declarative Configuration:

Edit the cfg.xml file to include the following XML code to declaratively configure the cache for replication mode (either synchronous or asynchronous): 

<infinispan xsi:schemaLocation="urn:infinispan:config:5.1 http://www.infinispan.org/schemas/infinispan-config-5.1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:infinispan:config:5.1">
   <global>
      <transport>
         <properties>
            <property name="configurationFile" value="jgroups.xml"/>
         </properties>
      </transport>
   </global>
   <default>
      <clustering mode="replication">
         <sync/>
      </clustering>
   </default>
</infinispan>
Copy to Clipboard Toggle word wrap
Use the following code to initialize and return a DefaultCacheManager with the XML configuration file: 
private static EmbeddedCacheManager createCacheManagerFromXml() throws IOException {
   return new DefaultCacheManager("infinispan-replication.xml");
}
