- Remove polling in SingleThreadEventExecutor - Create a dedicated scheduled task scheduler called 'TaskScheduler' - TaskScheduler is created per EventLoopGroup / EventExecutorGroup - SingleThreadEventExecutor delegates all scheduled execution requests to TaskScheduler provided as a constructor parameter - TaskScheduler is a specialized form of single threaded ScheduledExecutorService which requires an EventExecutor as a parameter for all requests.
