Reimplement NATS

This project is about implementing a simple NATS client and server. The first version from Derek Collision written in ruby on a weekend was handling around 150k msg/s. I aim to achieve the same - but not in a weekend. I will use Clojure for the project and learn netty to implement the transport layer. The code is available on my github page here.

Client

Implement a limited NATS client. The client should be able to

• create a connection to a nats server via TCP,
• parse the protocol and
• offer an API to use publish and subscribe.

Server

Implement a limited NATS server. The server should be able to

• accept connections from any number of clients,
• parse the protocol and
• handle subscriptions and forward published messages to all subscribers.

Benchmark

Implement a benchmark for the server and the client. Client and Server should be “interchangeable” with the actual implementations.
