- 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

金句 / Highlights
值得收藏与分享的关键句。
Vector excels at semantic similarity over unstructured content. Graphs excel at empirical queries: negation, date ranges, mathematical operations on connected data.
Schema-first retrieval where the agent pulls the full graph schema before deciding how to query.
Parallel execution across graph queries and vector retrieval, blended for the LLM.
Why Qdrant specifically: Hybrid Cloud kept the entire stack inside their own AWS environment.
The retrieval layer determines the ceiling of your AI's intelligence. Choose the right components. Compose them well.

Most "Graph RAG" implementations are vector retrieval with extra steps.
built something different. Their UK-based knowledge graph platform combines a proprietary graph database engine with Qdrant-powered semantic search, orchestrated by an agentic layer that picks the right retrieval path for each prompt. The insight from CEO Paul Wilton: vector and graph aren't competitors. They're complementary. Vector excels at semantic similarity over unstructured content. Graphs excel at empirical queries: negation, date ranges, mathematical operations on connected data. Force one to do the other's job and the system breaks. What they built: - Real-time embedding from the graph into Qdrant collections via streaming and queuing - Schema-first retrieval where the agent pulls the full graph schema before deciding how to query - Parallel execution across graph queries and vector retrieval, blended for the LLM - Every answer cited back to source for verifiable provenance Why Qdrant specifically: - Hybrid Cloud kept the entire stack inside their own AWS environment - Payload filtering DSL closely matched their existing OpenSearch patterns, so common metadata structures worked across the graph, OpenSearch, and Qdrant without translation - Terraform support and infrastructure automation fit their existing CI/CD workflows 18 months in production. Zero significant issues. The retrieval layer determines the ceiling of your AI's intelligence. Choose the right components. Compose them well. Full case study: qdrant.tech/blog/case-stud
