In this post from 2011, the creator of Omegle, Leif Brooks, explains what technology is used, including Python and a library called gevent for the backend. On top of that, Adobe Cirrus is used for streaming video. Though this post was 12 years ago, it is valuable to know what a web application like Omegle requires. A modern library that may provide some functionality for a text chat at a minimum may be... Source: 7 months ago

They might be thinking of something like ZeroMQ, which is pretty well liked: https://zeromq.org/ That said, I wouldn't call RabbitMQ that heavyweight myself, at least when compared to something like Apache Kafka. - Source: Hacker News / 8 months ago

If you want to learn message passing in an environment you're familiar with, you should check out ZeroMQ. It's a C++ lib for socket abstraction, it's immensely useful in distributed systems, it can also do in-process message passing, and it's got bindings/ports for C and Rust. Source: about 1 year ago

Inspired by the IDE language server protocol, I created an API interface between the electron and the Python ML interface. ZeroMQ turned out be an invaluable resource as a fast and lightweight messaging queue between the two. - Source: dev.to / about 1 year ago

If you really need it live, like for a chat or auctions you can use https://zeromq.org/ over websockets. Source: over 1 year ago

We use Netty (https://netty.io/) as the source of the MQTT communication, and we build the MQTT features the MQTT broker should support ourselves on top of that. - Source: Hacker News / 6 months ago

In this space, we also have the somewhat related term blocking. Java's NIO library is one well-known non-blocking tool used for managing multiple tasks on a single Java thread. When listening to sockets, most of the time a thread is just blocked, doing nothing until it receives some data. So, it's efficient to use a single thread for monitoring many sockets, to increase the likelihood of the thread having some... - Source: dev.to / 7 months ago

Given the fact that Lettuce is built with Netty, we also immediately noticed quite an impact on the initialization time (cold start) of our lambda function. Netty is really fast while executing, but takes a bit of time to initialize. The new Lambda Snapstart functionality might help with that. - Source: dev.to / about 1 year ago

Io.netty or netty.io is a Java network library, so it does stuff with servers (Minecraft's multiplayer, Chrome websites, local programs talking with each other etc.). Source: over 1 year ago

If you're still determined, I'll give you two options: 1. Sockets: A simple but primitive way of transferring and receiving data. Everything has to be done synchronously. 2. Netty: A much more robust and flexible asynchronous networking library, but requires much more boilerplate to get started. Source: over 1 year ago
