                                                                        ListenerParameters params)
        Creates a fixed thread pool executor service with daemon threads using pool size from listener parameters.
        Parameters:
        namePrefix - prefix for thread names created by this executor
        params - listener parameters containing IO pool size configuration
        Returns:

      • shutdownExecutorService

        public static void shutdownExecutorService​(@Nonnull
                                           java.util.concurrent.ExecutorService executorService,
                                           long duration,
                                           @Nonnull
                                           java.util.concurrent.TimeUnit timeUnit)
        Gracefully shuts down an executor service with a specified timeout. If the executor service doesn't terminate within the specified time, it will be forcibly shut down. If the shutdown is interrupted, the executor service will also be forcibly shut down.
        Parameters:
        executorService - the executor service to shut down, must not be null
        duration - the maximum time to wait for termination
        timeUnit - the time unit of the duration parameter, must not be null
