4.2.3 More Asynchronous Processing and Less Synchronous Processing

Information flow simultaneously passes through multiple systems with varying processing logic and throughput capabilities. Synchronous mechanisms may lead to upstream systems overwhelming downstream systems. Therefore, adopting an asynchronous mechanism is more viable. Asynchronous processing has two advantages. It acts as a buffer, allowing downstream systems to control the amount of data processed based on their capabilities, avoiding the impact of overload and ensuring stable system operation. Additionally, it achieves system isolation and decoupling. If a downstream system encounters an issue, the upstream system can still process data normally which prevents a chain reaction.
