## Health v2 (maintenance only)
Score: 62/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 71, release rhythm 35, longevity 90
- inputs: {"age_days": 1260, "days_push": 174, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
CongoMall is an open-source C-end (consumer-facing) e-commerce mall system built with Spring Cloud Alibaba microservices and DDD (Domain-Driven Design), covering user, product, order, coupon, payment, gateway, and shopping cart services. It doubles as an enterprise-grade learning project demonstrating distributed locks, distributed transactions, sharding, message queues, search, and bytecode-based traffic monitoring.

## Use cases
- learn how to build a microservices e-commerce system with Spring Cloud Alibaba
- study DDD domain-driven design in a real Java project
- understand sharding and distributed transactions with ShardingSphere and Seata
- practice implementing distributed locks, caching, and rate limiting
- prepare for backend engineer interviews with a real project for a resume
- learn how to build reusable infrastructure components like idempotency and distributed ID
- explore bytecode agent-based interface QPS and latency monitoring

## When to choose
- you want a realistic, enterprise-style Java microservices project to study or put on a resume
- you want to learn DDD applied to e-commerce business modules
- you need reference implementations of distributed systems patterns in Java

## When to avoid
- you need a production-ready, feature-complete storefront out of the box (frontend is incomplete)
- you are not working in the Java/Spring ecosystem
- you want a small, simple monolithic shop system rather than a full microservices stack

## Facets
- artifact type: learning-resource
- maturity: active
- function: microservices, caching, message-queue, search-engine, monitoring, api-gateway, database
- domain: e-commerce, microservices, developer-tools, tutorials
- platform: jvm, self-hosted
- tags: spring-cloud-alibaba, ddd, shardingsphere, distributed-lock, distributed-transaction, interview-preparation, rocketmq, seata, nacos, docker
