DevOps - Feature Flag-Driven Development
Feature Flag-Driven Development
DevOps 最佳实践
Continuous Delivery
Feature flag-driven 比 Agile & test-driven 的反馈周期更短,交付效率更高
Long Lived Branch
Merge Hell
TBD: Trunk based Development
不能随意开分支
Branch by Abstraction 重构 – 抽象接口 + 配置中心
案例:Feature flag-driven Development + Trunk based Development – 依赖于配置中心
Re-planning – 业务功能回退方便,非常灵活
Comparison
优势 | 劣势 |
---|---|
降低发布风险:通过开关,实现新功能和代码发布的分离 | 代码侵入,有技术债 - 个人不能接受 |
迭代速度快 | 需要配置中心支持 |
投入成本低:无需开发和维护复杂的发布系统 | 需要 DevOps 文化和流程配合 |
减少 Merge hell 问题 |
