Integrating with RabbitMQ/Kafka
Configure Spring WebSockets to use external message brokers for inter-server communication.
Scaling with External Brokers
When your WebSocket application runs on multiple server instances, an in-memory message broker isn't enough. You need an external message broker to coordinate messages across all instances.
This ensures that a message sent to one server can be received by a client connected to *any* server in your cluster, enabling true horizontal scaling.
Spring's Broker Bridge
Spring provides a powerful abstraction called the STOMP Broker Relay. This allows your Spring WebSocket application to delegate message routing to an external STOMP-compatible message broker.
Your application acts as a client to the external broker, sending and receiving messages on behalf of connected WebSocket clients.
