Title: I’ve been building Titan, a lightweight real-time message dispatcher in Java
Hey everyone,
I’ve been working on an open-source project called Titan. It’s a lightweight message dispatcher written in Java, focused on real-time, in-memory message delivery without requiring a large broker setup.
Titan currently supports:
- STOMP over TCP and WebSocket
- TLS and secure WebSocket connections
- Fan-out message delivery
- A Spring Boot client with listeners and automatic reconnection
- Native Titan and Vert.x client implementations behind the same API
- Queue and JVM monitoring through a small Go CLI
The networking layer is implemented directly on Java NIO, including the event loops, channel pipeline, WebSocket framing, and TLS handling. A lot of the recent work has been around connection stability, buffer ownership, flow control, and keeping the public client API simple.
Titan is still pre-1.0, so I’m not presenting it as a replacement for Kafka or RabbitMQ. It currently makes more sense for lightweight real-time dispatch where persistence and durable messaging are not required.
I’d especially appreciate feedback on the API, networking design, documentation, or anything that would make the project easier to try.
