MQTT Broker Cluster Scalability: How is done by EMQX

IoT infrastructure's scalability is essential for handling plenty of connections to meet the growing business demands. In this case, EMQX may be the best choice, cause it has been recently tested with 100 million connections. This video explains why EMQX is so scalable through several aspects, such as EMQX's foundation, clustering and demonstrates how to reach 100 thousand in the live show.

I see you have achieved 100M connections with 22 nodes. Do you have number of core nodes and leaf nodes and their respective sizing? What is minimum count of core nodes needed? Can I choose 3 or 4 or 5...? Any rationale there if any?! What is TPS achieved with this 22 node cluster? How many load balancers are used in this deployment? For example HAproxy published that they have achieved 2M connections with a 64 core ARM based system. Can I interpret in a way you need 50 HAproxy nodes to handle 100M connections? Have you used TLS & JWT in test setup? Have you used open source or enterprise version? How many emqtt_bench instaces are used? and their sizing?

Actually I am facing an issue i configured my nginx server and when a client tries to connect with the emqx broker it fails and the problem i can identify is because mqtt client is trying to connect using mqtt:// and my nginx server send the client using so can you share the nginx server configurations code?
