kkfileview's Coping Strategies and Practices in High Concurrent Scenarios

# 1.1 What is a High-Concurrency Scenario

In the realm of Information Technology, a high-concurrency scenario refers to a system facing a large number of concurrent requests at the same moment. The characteristics of these scenarios include instantaneous high concurrency, a massive influx of requests arriving simultaneously, and the need to process complex business logic. Typical examples include flash sales on e-commerce websites and a sudden surge in the number of concurrent users on popular live-streaming platforms. In these cases, systems must possess a higher capacity for performance and data processing while ensuring data consistency and stability. High-concurrency scenarios often impose significant pressure on system performance, necessitating targeted architectural designs and optimization strategies to address the challenges.

Summary: A high-concurrency scenario refers to a system that simultaneously faces a large number of concurrent requests, characterized by high concurrency, a massive influx of requests, and complex business logic; examples include flash sales and live-streaming platforms; challenges to system performance and data consistency.
