Evolution of a Message Platform from v1.0 to v3.0
The DeWu App’s messaging platform progressed from a tightly‑coupled v1.0 push API plagued by latency and priority issues to a v2.0 unified interface with fatigue control, multi‑version sending, and robust monitoring, and finally to a v3.0 modular, stateless architecture driven by an orchestration engine that separates core capabilities from business extensions while providing dynamic strategies, SLA‑level latency guarantees, and comprehensive stability monitoring.
The article describes the progressive redesign of a messaging platform used by the DeWu App, outlining the challenges faced as business volume and integration complexity grew.
In version 1.0, each business called push/notice APIs directly, leading to tightly coupled logic, no priority control, and a single channel that caused latency and stability issues, especially when marketing messages flooded the system.
Version 2.0 introduced a unified external interface with business identity, added common capabilities such as fatigue control, priority, do‑not‑disturb, multi‑version sending, and switched to a high‑write, low‑read database. Monitoring and fast alerting were also incorporated.
Version 3.0 further separates core platform capabilities from business‑specific extensions, defines independent, stateless ability points, and employs a business orchestration engine to apply strategies dynamically. The architecture adds comprehensive SLA monitoring for latency and stability.
The future roadmap focuses on improving workflow orchestration, dynamic business extensions, stability guarantees, and a more complete monitoring system.
Overall, the platform evolved from a simple push service to a modular, extensible system that balances shared core functions with customizable business logic, enhancing development efficiency and operational reliability.
