Supposed configuration (part of): advertised.listeners=EXTERNAL://broker1.subnet1.localdomain:9993,EXTERNAL://broker2.subnet1.localdomain:9993,EXTERNAL://broker1.subnet2.localdomain:9993,EXTERNAL://broker2.subnet2.localdomain:9993,EXTERNAL://broker1.subnet3.localdomain:9993,EXTERNAL://broker2.subnet3.localdomain:9993,INTERNAL://broker1.internalsubnet.localdomain:9990 inter.broker.listener.name=INT...

So, what are the advantages of the kafka client? Which Kafka Client? Java? Rdkafka? – cricket_007 2 days ago @cricket_007 Java client. i don't know Rdkafka – 김태우 yesterday Well, the REST Proxy uses the Java client internally, so I don't don't really understand your question. The main benefit would be scalability ov...
