| 在引入工作负载策略层之前，OME的工作负载部署逻辑紧耦合在各个角色的Reconciler中，每个组件独立创建Deployment、Service、Knative Service等资源。这种架构存在以下问题： | ||

| 1. **扩展性受限**：只支持每个角色有自己独立的资源，无法支持多个角色共用一个工作负载，难以支持All-in-One工作负载类型如RBG、Grove等 |

- 可运维性不足：
- 不支持镜像原地升级：现有工作负载在镜像更新时必须重建 Pod，导致服务中断或延迟，拖慢整体发布效率。
- 缺少指定预热控制能力。
2. 多角色协同能力弱 - 缺乏跨角色统一编排：各角色独立调谐，无法感知彼此的版本、状态或依赖关系。在扩容或升级时，不能保证角色间的版本一致性或比例协调（比如“先升 A 再升 B”、“A:B = 2:1”等策略），容易引发兼容性问题或服务异常。
