public interface IRemoteExecutor
extends Remote

Interface for running procedures on a remote service. In general, applications SHOULD restrict their discovery of IRemoteExecutor to IClientServices. Applications SHOULD NOT run arbitrary Callables against an IDataService or an IMetadataService unless it is necessary to access the index objects locally on the service (index partition moves, scale-out joins, and rule execution all do this).
