Going Infinite, handling 1M websockets connections in Go
This repository holds the complete implementation of the examples seen in Gophercon Israel talk, 2019.
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.
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>
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.
