Hi Yukon, I will continue my discussion here from now on (Which I continued on JIRA). As per my understanding, MQTT protocol follows a publisher subscriber publish subscribe architecture. I read the RocketMQ documentation and it occurred to me that, message broadcasting using RocketMQ can be used here. I ran these examples and I got a brief knowledge on working with message broadcasting with RocketMQ. I thought of a setup where each IoT Sensor(device which produces messages) sends messages with a unique topic. So the subscribers can subscribe to the message stream using the same unique topic. I sketched my current idea like this.
But still I'm not sure this requires separate proxy for publishers and a separate proxy for subscribers. Can you please input your suggestions. Thank you.
