As the business becomes more and more complex, the amount of data is getting larger and larger, and the amount of concurrency is becoming larger and larger. The single-mode architecture model can no longer correspond. As a Java back-end architect, high concurrency + high availability + Distributed architecture system of massive data is essential.
