## What it is
A Chinese-language educational repository explaining the design and implementation of high-concurrency flash-sale (seckill) systems in Java, with notes, diagrams, and demo projects covering Redis, MQ, Spring Boot, and related distributed systems topics. It also links to companion learning projects on multithreading, JVM tuning, ZooKeeper, and design patterns.

## Use cases
- learn how to design a flash sale system
- understand high-concurrency seckill architecture
- prepare for backend engineer interviews on spike systems
- study Redis and MQ patterns for traffic spikes
- learn JVM tuning and multithreading for Java backends
- find reference code for rate limiting and inventory oversell prevention

## When to choose
- you are a Java developer learning distributed system design patterns
- you want annotated examples and diagrams for seckill-style traffic
- you are preparing for interviews about high-concurrency e-commerce systems

## When to avoid
- you need a production-ready flash-sale service to deploy as-is
- you need a maintained, licensed library rather than tutorial material
- you work outside the Java/Spring ecosystem

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, caching, message-queue, monitoring
- domain: developer-tools, backend, microservices, tutorials, e-commerce
- platform: jvm, self-hosted
- tags: flash-sale, seckill, system-design, high-concurrency, redis, spring-boot, interview-prep, architecture
