千万级文档企业 RAG 系统设计

🎯Core Definition

The Enterprise RAG System Architecture for 10 Million Documents represents the definitive enterprise GenAI system design benchmark, scaling heterogeneous ingestion, sub-second hybrid retrieval, and strict enterprise security over tens of millions of documents; the 5-tier architecture comprises: 1) Distributed Ingestion Pipeline (Kafka + Ray clusters executing OCR table extraction, hierarchical Parent-Child chunking, and batched BGE-M3 embeddings); 2) Scalable Hybrid Storage (Milvus/Qdrant HNSW clusters with horizontal sharding + Elasticsearch BM25 cluster); 3) Sub-50ms Online Gateway (5ms Semantic Cache

\to

15ms Parallel Hybrid Retrieval

\to

RRF Rank Fusion

\to

20ms Cross-Encoder Re-ranking); 4) Security Boundary (RBAC ACL payload filtering + Llama-Guard injection firewall); 5) Grounded Generation with Inline Citations (verifying factuality before emission).

💡Use Cases

Multi-national enterprise knowledge brain, financial investment research Q&A, and comprehensive legal regulatory compliance portals.

⚡Key Problems Solved

Naive toy RAG demos crash when scaled to millions of documents and produce ungrounded hallucinations; enterprise architectures deliver millisecond hybrid latency, linear scale-out, and bulletproof fact grounding.
