Class MultiThreadIoEventLoopGroup

io.netty.channel.MultiThreadIoEventLoopGroup

All Implemented Interfaces:: EventLoopGroup, IoEventLoopGroup, EventExecutorGroup, Iterable<EventExecutor>, Executor, ExecutorService, ScheduledExecutorService

Direct Known Subclasses:: EpollEventLoopGroup, KQueueEventLoopGroup, LocalEventLoopGroup, NioEventLoopGroup

public class MultiThreadIoEventLoopGroup extends MultithreadEventLoopGroup implements IoEventLoopGroup

IoEventLoopGroup implementation that will handle its tasks with multiple threads.

This group supports advanced thread management strategies, such as dynamic auto-scaling, by providing a custom EventExecutorChooserFactory. To enable utilization-based auto-scaling, pass an instance of AutoScalingEventExecutorChooserFactory.
