<pre>public interface <span class="strong">IgniteCompute</span>
extends <a href="../../../org/apache/ignite/lang/IgniteAsyncSupport.html" title="interface in org.apache.ignite.lang">IgniteAsyncSupport</a></pre>
<div class="block">Defines compute grid functionality for executing tasks and closures over nodes
in the <a href="../../../org/apache/ignite/cluster/ClusterGroup.html" title="interface in org.apache.ignite.cluster"><code>ClusterGroup</code></a>. Instance of <code>IgniteCompute</code> is obtained from <a href="../../../org/apache/ignite/Ignite.html" title="interface in org.apache.ignite"><code>Ignite</code></a>
as follows:
<pre name="code" class="java">
Ignite ignite = Ignition.ignite();
// Compute over all nodes in the cluster.
IgniteCompute c = ignite.compute();
</pre>
You can also get an instance of <a href="../../../org/apache/ignite/IgniteCompute.html" title="interface in org.apache.ignite"><code>IgniteCompute</code></a> over a subset of cluster nodes, i.e. over
a <a href="../../../org/apache/ignite/cluster/ClusterGroup.html" title="interface in org.apache.ignite.cluster"><code>ClusterGroup</code></a>:
<pre name="code" class="java">
// Cluster group composed of all remote nodes.
ClusterGroup rmtGrp = ignite.cluster().forRemotes();
// Compute over remote nodes only.
IgniteCompute c = ignite.compute(rmtGrp);
</pre>
The methods are grouped as follows:
<ul>
<li><code>apply(...)</code> methods execute <a href="../../../org/apache/ignite/lang/IgniteClosure.html" title="interface in org.apache.ignite.lang"><code>IgniteClosure</code></a> jobs over nodes in the cluster group.</li>
<li><code>call(...)</code> methods execute <a href="../../../org/apache/ignite/lang/IgniteCallable.html" title="interface in org.apache.ignite.lang"><code>IgniteCallable</code></a> jobs over nodes in the cluster group.</li>
<li><code>run(...)</code> methods execute <a href="../../../org/apache/ignite/lang/IgniteRunnable.html" title="interface in org.apache.ignite.lang"><code>IgniteRunnable</code></a> jobs over nodes in the cluster group.</li>
<li><code>broadcast(...)</code> methods broadcast jobs to all nodes in the cluster group.</li>
<li><code>affinityCall(...)</code> and <code>affinityRun(...)</code> methods collocate jobs with nodes
on which a specified key is cached.</li>
</ul>
Note that if attempt is made to execute a computation over an empty cluster group (i.e. cluster group
that does not have any alive nodes), then <a href="../../../org/apache/ignite/cluster/ClusterGroupEmptyException.html" title="class in org.apache.ignite.cluster"><code>ClusterGroupEmptyException</code></a>
will be thrown out of result future.
<h1 class="header">Load Balancing</h1>
In all cases other than <code>broadcast(...)</code>, Ignite must select a node for a computation
to be executed. The node will be selected based on the underlying <a href="../../../org/apache/ignite/spi/loadbalancing/LoadBalancingSpi.html" title="interface in org.apache.ignite.spi.loadbalancing"><code>LoadBalancingSpi</code></a>,
which by default sequentially picks next available node from the underlying cluster group. Other
load balancing policies, such as <code>random</code> or <code>adaptive</code>, can be configured as well by
selecting a different load balancing SPI in Ignite configuration. If your logic requires some custom
load balancing behavior, consider implementing <a href="../../../org/apache/ignite/compute/ComputeTask.html" title="interface in org.apache.ignite.compute"><code>ComputeTask</code></a> directly.
<h1 class="header">Fault Tolerance</h1>
Ignite guarantees that as long as there is at least one grid node standing, every job will be
executed. Jobs will automatically failover to another node if a remote node crashed
or has rejected execution due to lack of resources. By default, in case of failover, next
load balanced node will be picked for job execution. Also jobs will never be re-routed to the
nodes they have failed on. This behavior can be changed by configuring any of the existing or a custom
<a href="../../../org/apache/ignite/spi/failover/FailoverSpi.html" title="interface in org.apache.ignite.spi.failover"><code>FailoverSpi</code></a> in grid configuration.
<h1 class="header">Resource Injection</h1>
All compute jobs, including closures, runnables, callables, and tasks can be injected with
ignite resources. Both, field and method based injections are supported. The following grid
resources can be injected:
<ul>
<li><a href="../../../org/apache/ignite/resources/TaskSessionResource.html" title="annotation in org.apache.ignite.resources"><code>TaskSessionResource</code></a></li>
<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.
Here is an example of how to inject instance of <a href="../../../org/apache/ignite/Ignite.html" title="interface in org.apache.ignite"><code>Ignite</code></a> into a computation:
<pre name="code" class="java">
public class MyIgniteJob extends IgniteRunnable {
...
&#64;IgniteInstanceResource
private Ignite ignite;
...
}
</pre>
<h1 class="header">Computation SPIs</h1>
Note that regardless of which method is used for executing computations, all relevant SPI implementations
configured for this compute instance will be used (i.e. failover, load balancing, collision resolution,
checkpoints, etc.). If you need to override configured defaults, you should use compute task together with
<a href="../../../org/apache/ignite/compute/ComputeTaskSpis.html" title="annotation in org.apache.ignite.compute"><code>ComputeTaskSpis</code></a> annotation. Refer to <a href="../../../org/apache/ignite/compute/ComputeTask.html" title="interface in org.apache.ignite.compute"><code>ComputeTask</code></a> documentation for more information.</div>
