    DistributedObject, java.util.concurrent.Executor, java.util.concurrent.ExecutorService
    public interface IExecutorService
extends java.util.concurrent.ExecutorService, DistributedObject
    Distributed implementation of ExecutorService. IExecutorService provides additional methods like executing tasks on a specific member, on a member who is owner of a specific key, executing a tasks on multiple members and listening execution result using a callback. Supports split brain protection SplitBrainProtectionConfig since 3.10 in cluster versions 3.10 and higher.
