For example, data forwarding can be triggered based on specific conditions, unnecessary data can be filtered out, or data granularity can be adjusted as needed. This flexibility enables EMQX to better serve the complex and ever-changing requirements of AI models.

Intelligent Scheduling in Globalized Distributed Systems

In AI applications, fast and real-time data transmission directly impacts decision accuracy and timeliness. EMQX 5.0's Core and Replica architecture creates an efficient, low-latency global distributed system, emphasizing efficient data circulation, intelligent scheduling, and secure transmission in complex, large-scale AI data processing.

1. Advantages of Global Deployment: EMQX 5.0's Core and Replica architecture allows for efficient scaling and global deployment of MQTT Brokers. It reduces latency by enabling clients to connect to the nearest node. The Core nodes are responsible for routing information and maintaining global state, while Replica nodes serve as data backups and handle client connection requests. The public MQTT Broker uses this architecture with multiple Replica nodes in Virginia, Oregon, and Ireland. Through DNS smart resolution, devices from Europe, Eastern US, Western US, and Asia can respectively connect to the nearest node. This ensures device connections are not affected if one node fails since they can switch to other replicas.
2. Intelligent Scheduling and Low-Latency Transmission: When devices connect to their nearest Replica node, they can subscribe and consume data closer to their geographical location. For example, European devices can directly connect to the Irish Replica node for nearby data processing. This reduces message transmission latency and aligns with data compliance and security requirements.
3. Integration of Edge Intelligence: Data in distributed systems also needs fast processing at the edge. AI data center nodes can receive data from various Replica nodes, perform quick analysis and processing, and provide real-time feedback to relevant devices.
