What is Java Netty?

Java Netty is an asynchronous event-driven network application framework used for rapid development of maintainable high-performance protocol servers and clients. It simplifies network programming such as TCP and UDP socket server development, making it easier to build scalable and reliable network applications in Java. Netty is commonly used in applications requiring fast, non-blocking I/O, such as messaging systems, proxy servers, and real-time communication platforms.
