| <div class="block">Defines functionality necessary to deploy distributed services on the grid. |
| <p> |
| Instance of <code>IgniteServices</code> which spans all cluster nodes can be obtained from Ignite as follows: |
| <pre class="brush:java"> |
| Ignite ignite = Ignition.ignite(); |
| |
| IgniteServices svcs = ignite.services(); |
| </pre> |
| You can also obtain an instance of the services facade over a specific cluster group: |
| <pre class="brush:java"> |
| // Cluster group over remote nodes (excluding the local node). |
| ClusterGroup remoteNodes = ignite.cluster().forRemotes(); |
| |
| // Services instance spanning all remote cluster nodes. |
| IgniteServices svcs = ignite.services(remoteNodes); |
| </pre> |
| <p> |
| With distributed services you can do the following: |
| <ul> |
| <li>Automatically deploy any number of service instances on the grid.</li> |
| <li> |
| Automatically deploy singletons, including <b>cluster-singleton</b>, |
| <b>node-singleton</b>, or <b>key-affinity-singleton</b>. |
| </li> |
| <li>Automatically deploy services on node start-up by specifying them in grid configuration.</li> |
| <li>Undeploy any of the deployed services.</li> |
| <li>Get information about service deployment topology within the grid.</li> |
| </ul> |
| <h1 class="header">Deployment From Configuration</h1> |
| In addition to deploying managed services by calling any of the provided <code>deploy(...)</code> methods, |
| you can also automatically deploy services on startup by specifying them in <a href="../../../org/apache/ignite/configuration/IgniteConfiguration.html" title="class in org.apache.ignite.configuration"><code>IgniteConfiguration</code></a> |
| like so: |
| <pre name="code" class="java"> |
| IgniteConfiguration cfg = new IgniteConfiguration(); |
| |
| ServiceConfiguration svcCfg1 = new ServiceConfiguration(); |
| |
| // Cluster-wide singleton configuration. |
| svcCfg1.setName("myClusterSingletonService"); |
| svcCfg1.setMaxPerNodeCount(1); |
| svcCfg1.setTotalCount(1); |
| svcCfg1.setService(new MyClusterSingletonService()); |
| |
| ServiceConfiguration svcCfg2 = new ServiceConfiguration(); |
| |
| // Per-node singleton configuration. |
| svcCfg2.setName("myNodeSingletonService"); |
| svcCfg2.setMaxPerNodeCount(1); |
| svcCfg2.setService(new MyNodeSingletonService()); |
| |
| cfg.setServiceConfiguration(svcCfg1, svcCfg2); |
| ... |
| Ignition.start(cfg); |
| </pre> |
| <h1 class="header">Load Balancing</h1> |
| In all cases, other than singleton service deployment, Ignite will automatically make sure that |
| an about equal number of services are deployed on each node within the grid. Whenever cluster topology |
| changes, Ignite will re-evaluate service deployments and may re-deploy an already deployed service |
| on another node for better load balancing. |
| <h1 class="header">Fault Tolerance</h1> |
| Ignite guarantees that services are deployed according to specified configuration regardless |
| of any topology changes, including node crashes. |
| <h1 class="header">Resource Injection</h1> |
| All distributed services can be injected with |
| ignite resources. Both, field and method based injections are supported. The following ignite |
| resources can be injected: |
| <ul> |
| <li><a href="../../../org/apache/ignite/resources/IgniteInstanceResource.html" title="annotation in org.apache.ignite.resources"><code>IgniteInstanceResource</code></a></li> |
| <li><a href="../../../org/apache/ignite/resources/LoggerResource.html" title="annotation in org.apache.ignite.resources"><code>LoggerResource</code></a></li> |
| <li><a href="../../../org/apache/ignite/resources/SpringApplicationContextResource.html" title="annotation in org.apache.ignite.resources"><code>SpringApplicationContextResource</code></a></li> |
| <li><a href="../../../org/apache/ignite/resources/SpringResource.html" title="annotation in org.apache.ignite.resources"><code>SpringResource</code></a></li> |
| </ul> |
| Refer to corresponding resource documentation for more information. |
| <h1 class="header">Service Example</h1> |
| Here is an example of how an distributed service may be implemented and deployed: |
| <pre name="code" class="java"> |
| // Simple service implementation. |
| public class MyIgniteService implements Service { |
| ... |
| // Example of ignite resource injection. All resources are optional. |
| // You should inject resources only as needed. |
| @IgniteInstanceResource |
| private Ignite ignite; |
| ... |
| @Override public void cancel(ServiceContext ctx) { |
| // No-op. |
| } |
| |
| @Override public void execute(ServiceContext ctx) { |
| // Loop until service is cancelled. |
| while (!ctx.isCancelled()) { |
| // Do something. |
| ... |
| } |
| } |
| } |
| ... |
| IgniteServices svcs = ignite.services(); |
| |
| svcs.deployClusterSingleton("mySingleton", new MyIgniteService()); |
| </pre></div> |
