## Summary

Qdrant 指出多数“图RAG”实为套壳向量检索，而 @datagraphs 构建了真正融合图数据库与向量搜索的协同架构：通过 schema-first agent 调度并行图查与语义检索，实现可验证、低延迟、全栈可控的知识问答。

## Key Takeaways

- 图与向量非互斥，而是互补：图擅精确逻辑查询（否定/时间/计算），向量擅语义相似匹配
- 真实图RAG需schema感知agent调度、实时图嵌入同步、图/向量并行检索与结果融合
- Qdrant被选中主因是混合云部署能力、payload过滤DSL兼容性及Terraform原生支持

## Outline

- 行业误区揭示 — 指出当前多数'Graph RAG'本质仍是向量检索，仅叠加图结构外壳。
  - datagraphs 架构创新 — 提出真正协同架构：图引擎+Qdrant语义搜索+agentic路径决策层。
  - 技术协同原理 — 阐明图与向量的分工边界——图处理逻辑约束，向量处理语义模糊匹配。
    - 关键工程实践 — 包括schema-first检索、流式图嵌入同步、并行执行与结果融合、源追溯机制。
    - Qdrant选型依据 — 聚焦混合云控制、payload DSL兼容性、Terraform自动化三大落地优势。
- 核心启示 — 检索层决定AI智能上限，关键在组件选型与高质量组合。

## Highlights

- > Vector excels at semantic similarity over unstructured content. Graphs excel at empirical queries: negation, date ranges, mathematical operations on connected data. — 正文第3段
- > Schema-first retrieval where the agent pulls the full graph schema before deciding how to query. — 正文第4段
- > Parallel execution across graph queries and vector retrieval, blended for the LLM. — 正文第4段
- > Why Qdrant specifically: Hybrid Cloud kept the entire stack inside their own AWS environment. — 正文第5段
- > The retrieval layer determines the ceiling of your AI's intelligence. Choose the right components. Compose them well. — 结尾总结句
