Going Infinite, handling 1M websockets connections in Go
This repository holds the complete implementation of the examples seen in Gophercon Israel talk, 2019.
Going Infinite, handling 1 millions websockets connections in Go / Eran Yanay — [ Video | Slides ]
It doesnt intend or claim to serve as a better, more optimal implementation than other libraries that implements the websocket protocol, it simply shows a set of tools, all combined together to demonstrate a server written in pure Go that is able to serve more than a million websockets connections with less than 1GB of ram.
Usage
This repository demonstrates how a very high number of websockets connections can be maintained efficiently in Linux
Everything is written in pure Go
Each folder shows an example of a server implementation that overcomes various issues raised by the OS, by the hardware or the Go runtime itself, as shown during the talk.
setup.sh is a wrapper to running multiple instances using Docker. See content of the script for more details of how to use it.
destroy.sh is a wrapper to stop all running clients.
A single client instance can be executed by running go run client.go -conn=<# connections to establish>
Remarks
This repo consists of a set of examples that were demonstrated during a live talk in Gophercon.
What you see is what you get - while the implementation is fully functional, it doesn't intend to serve as a production-ready code, and no new features that were asked will be added.
The only purpose of this repository is to serve as a reference and a case study.
