# RAG Pipeline — 可插拔 RAG 编排引擎
|
||||
|
||||
## 概述
|
||||
|
||||
RAG Pipeline 是一个可插拔的 RAG (检索增强生成) 编排服务,支持知识图谱增强的多模态检索。通过插件注册表,所有底层引擎(向量化、向量库、图数据库、重排器)均可替换。
|
||||
|
||||

## 插件槽位
|
||||
|
||||
| 槽位 | 当前实现 | 可替换为 |
|
||||
|------|---------|---------|
|
||||
| embedding | CLIP-ViT-H/14 (9086) | BGE-M3, OpenAI embedding |
|
||||
| vdb | Milvus VDB (8886) | Qdrant, Weaviate |
|
||||
| graph | NetworkX (9092) | FalkorDB, Neo4j |
|
||||
| reranker | BGE-Reranker (9090) | Cohere, LLM rerank |
|
||||
| llm | harnessed_agent | 任意 LLM |
|
||||
| chunker | recursive/sentence | 自定义分块策略 |
|
||||
| extractor | LLM-structured | spaCy, GraphRAG |
|
||||
| retriever | hybrid/vector_only | 自定义检索策略 |
|
||||
| face | InsightFace (9091) | FaceNet, DeepFace |
|
||||
|
||||
## Pipeline 配置
|
||||
|
||||
### kg-rag-standard(标准版)
|
||||
- CLIP embedding + Milvus + NetworkX 图 + BGE Rerank
|
||||
- 向量召回 + 图扩展 + RRF 融合 + 精排
|
||||
|
||||
### kg-rag-lite(轻量版)
|
||||
- CLIP embedding + Milvus + BGE Rerank
|
||||
- 纯向量检索,无图谱
|
||||
|
||||
## API
|
||||
|
||||
### GET /api/status — 服务状态和可用插件列表
|
||||
|
||||
### POST /api/ingest — 入库文档
|
||||
```json
|
||||
{"document": "文本内容...", "pipeline": "kg-rag-standard", "collection": "knowledge", "graph_name": "knowledge"}
|
||||
```
|
||||
流程: 分块 → CLIP embedding → VDB 存储 → 实体抽取 → 图存储
|
||||
|
||||
### POST /api/search — 混合检索
|
||||
```json
|
||||
{"query": "搜索问题", "pipeline": "kg-rag-standard", "top_k": 5}
|
||||
```
|
||||
流程: CLIP embed → VDB 向量召回 → 图扩展 → RRF 融合 → BGE Rerank → 答案生成
|
||||
|
||||
### GET/POST /api/pipelines — 管理 pipeline 配置
|
||||
|
||||
### GET /api/plugins — 列出所有可用插件及状态
|
||||
|
||||
## 部署
|
||||
|
||||
```bash
|
||||
cd /data/ymq/rag-pipeline
|
||||
bash build.sh deploy
|
||||
bash build.sh stop
|
||||
bash build.sh status
|
||||
```
|
||||
|
||||
## 端到端测试
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:9093/api/ingest \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"document":"张三在ABC公司担任技术总监,他和李四是同事关系。"}'
|
||||
|
||||
curl -X POST http://localhost:9093/api/search \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"query":"张三在哪家公司工作?"}'
|
||||
```
|
||||
|
||||
## 端口
