public interface IExecutorService
extends 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 Quorum QuorumConfig since 3.10 in cluster versions 3.10 and higher.
