Hello everyone,
I’m planning to develop a real-time chat application for the web using Java Enterprise Edition as my server-side technology. My goal is to create something that can handle heavy traffic without performance issues.
I’m looking for guidance on the optimal system design and architectural patterns I should implement. The application needs to support many concurrent users and maintain fast response times even under high load conditions.
What would be the recommended technical approach for building such a scalable messaging platform? Any suggestions on frameworks, design patterns, or infrastructure considerations would be greatly appreciated.
Thanks in advance for your help!
for sure! websockets with spring boot & netty are gr8 for heavy load. don’t forget redis for managing sessions. also, think about microservices early on if you wanna scale up smoothly, trust me, it’s worth it!
I’ve built several high-traffic messaging systems, and you definitely need a message queue like Kafka or RabbitMQ as your backbone. This becomes critical with thousands of concurrent connections. For WebSockets, use async processing with CompletableFuture - you don’t want blocking operations killing your performance. Partition your database by room or user groups to avoid bottlenecks. Set up proper connection pooling and throw a CDN in front of your static assets. Use load balancing with sticky sessions to keep WebSocket connections stable during scaling. Watch your memory usage like a hawk - chat apps pile up connection objects fast.
cool project! what messaging patterns are you planning? do users need instant delivery or is some delay okay? and what’s your database plan - sql or nosql for chat history?
