An XNIO worker is the central point of coordination for a network application. It manages several kind of threads, and the threads created by the worker are tagged with the worker name. A worker has two different types of thread pools:

I/O Threads

The I/O threads come in two types:

• Read threads that can handle callbacks for read events.
• Write threads that can handle callback for write events.

Worker Threads

The worker threads are managed by a standard Executor-based thread pool.
