public interface DistributedExecutorService extends ExecutorService
Every DistributedExecutorService is bound to one particular cache. Tasks submitted will have
access to key/value pairs from that particular cache if and only if the task submitted is an
instance of DistributedCallable. Also note that there is nothing preventing a user from
submitting a familiar Runnable or Callable just like to any other
ExecutorService. However, DistributedExecutorService, as it name implies, will likely
migrate submitted Callable or Runnable to another JVM in Infinispan cluster, execute it and
return a result to task invoker.
Note that due to potential task migration to other nodes every Callable,
Runnable and/or DistributedCallable submitted must be either Serializable
or Externalizable. Also the value returned from a callable must be Serializable
or Externalizable. Unfortunately if the value returned is not serializable then a
NotSerializableException will be thrown.
DefaultExecutorService,
DistributedCallable| Modifier and Type | Method and Description |
|---|---|
<T,K> Future<T> |
submit(Callable<T> task,
K... input)
Submits given Callable task for an execution on a single Infinispan node.
|
<T> List<Future<T>> |
submitEverywhere(Callable<T> task)
Submits the given Callable task for an execution on all available Infinispan nodes.
|
<T,K> List<Future<T>> |
submitEverywhere(Callable<T> task,
K... input)
Submits the given Callable task for an execution on all available Infinispan nodes using input
keys specified by K input.

Execution environment will chose an arbitrary node N hosting some or all of the keys specified as input. If all keys are not available locally at node N they will be retrieved from the cluster.
