Doraemon Marketing Activity Platform: Architecture, Challenges, and Solutions

The article introduces the Doraemon platform built for Xianyu to centralize and streamline user‑rights marketing activities such as red packets, coupons, and vouchers. It explains the background of fragmented, low‑frequency, manual campaigns and the need for a reusable, configurable solution.

Key pain points are identified for development (long cycles, difficulty locating bugs), operations (complex configuration, high communication cost, delayed effect monitoring), and testing (high cost, long feedback loops). Based on these, three primary goals are set: reusable capabilities, operator‑friendly configuration, and rapid issue detection.

The platform’s architecture is divided into three layers: an external‑dependency layer (task, crowd, behavior, recommendation, reconciliation, and notification systems), a core system layer (encapsulating activity concepts, logging, monitoring, reconciliation, and reporting), and a business layer (frontend components offering various game‑style activities).

The operation configuration portal enables non‑technical staff to launch activities by defining rules and rights per user segment (e.g., gender). Decision logic can be weight‑based or algorithmic to maximize rights efficiency.

For development, the platform addresses traffic spikes, illegal traffic, and security concerns through DDoS/CC protection, rate limiting, RMB anti‑fraud checks, distributed locks, and activity‑code verification. Real‑time and offline reconciliation ensure data consistency.

Testing tools provide fast user‑profile generation via whitelist mechanisms and detailed logging via Spring AOP. Two logging strategies—coarse for production users and fine‑grained for test users—balance observability and performance.

Finally, the article showcases several activity types realized on Doraemon and outlines future plans to decouple the platform’s capabilities for broader reuse.
