Evolution and Technical Refactoring of Alibaba's Coupon Package System

The article traces the evolution of Alibaba's coupon package (卡券包) product from its initial PC‑only launch in 2014 through the wireless era, marketing‑driven iterations, and the current user‑asset‑centered version.

Early versions focused on basic coupon and red‑packet display, using hard‑coded logic and simple factory patterns. As mobile traffic grew, a wireless version added richer entry points such as a nine‑grid homepage and expanded asset types (shopping cards, payment red‑packets, etc.).

The marketing‑centric version (2018‑2020) introduced heavy promotional elements, recommendation algorithms, and extensive scenario‑based features, but suffered from performance issues and high resource consumption.

The current version (2019‑present) refocuses on functional core, re‑positions the coupon package as a user asset center, classifies assets into coupons, red‑packets, cards, tickets, and adopts a scenario‑driven, configuration‑separated architecture. Major refactoring efforts include technology stack upgrades (JDK7→8, Spring2.5→5, Maven2→3), logging unification, Dockerfile optimization, dependency governance, and environment consolidation.

Performance optimizations such as RPC merging, caching, peak‑tier degradation, and link‑chain cleanup reduced machine scale by over 90% and cut downstream request expansion by 90%. Ongoing work emphasizes deepening the user‑asset role, enriching benefit coverage, improving list‑page clarity, supporting bidirectional business links, strengthening foundational link‑through, and enabling differentiated scenario support.
