Implementing Reactive Client-Server Communication over TCP or Websockets with RSocket and Java

Sun, 25 Nov 2018 00:00:00 +0100

Reactive design or reactive architecture has an impact on how modern software systems are implemented. RSocket is a project that aims to adapt the benefits of the patterns described in the Reactive Manifesto and resulting tools like Reactive Streams or Reactive Extensions to a formal new communication protocol.

RSocket works with TCP, WebSockets and Aeron transport layers and offers additional features like session resumption.

In the following tutorial I’m going to demonstrate how to implement simple client-server communication over TCP and Websockets for different interaction models like request-response, request-stream, fire-and-forget and event subscription.

The MQ Telemetry Transport Protocol (MQTT) is a lightweight publish/subscribe messaging protocol developed in 1999 that experiences a growing popularity due to trends like the Internet-of-Things and the need to exchange information between low powered devices with aspects as CPU and bandwidth usage in mind.

In the following tutorial I’d like to demonstrate how to set-up a broker for this protocol with the help of the Moquette library and how to create a client and publish messages for a specific topic using this broker and Eclipse Paho as client library.
