Interface DistributedExecutorService

  • All Superinterfaces:
    Executor, ExecutorService
    All Known Implementing Classes:
    DefaultExecutorService
    public interface DistributedExecutorService
extends ExecutorService
    Deprecated.
    since 9.1 Please use ClusterExecutor or CacheStream instead.
    An ExecutorService that provides methods to submit tasks for execution on a cluster of Infinispan nodes.

    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.

    All CompletableFuture returned to the caller may be cancelled, however if interruption is desired, (ie. mayInterruptIfRunning == true), it will only be performed if done on the original CompletableFuture returned via one of the various submit methods. Any chained futures from the original will only attempt to cancel the task result. If interruption is needed and this task was found to be operating on a remote node it will send a cancellation command to the remote node in an attempt to stop it early using standard java Thread.interrupt() on the thread processing that task.

        Deprecated.
        Submits the given Callable task for execution on a single Infinispan node.

        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.

        Parameters:
        task - a task to execute across Infinispan cluster
        input - input keys for this task, effective if and only if task is instance of DistributedCallable
        Returns:
        a Future representing pending completion of the task

      • submit

        Deprecated.
        Submits the given DistributedTask for execution on a single Infinispan node.

        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.

        Parameters:
        task - a DistributedTask to execute across Infinispan cluster
        input - input keys for this task, effective if and only if task's callable is instance of DistributedCallable
