BEYOND VECTOR-ONLY RAG

Enterprise Knowledge Graph +GraphRAG, Sub-800ms at 100M+ Entities

When relationships drive the answer — KYC chains, supplier-defect networks, account-deal intelligence — vector similarity is not enough. We design and ship GraphRAG systems on Neo4j AuraDB, Amazon Neptune, and TigerGraph that traverse 100M+ entities in under 800ms with cited, auditable answers.

WHY VECTOR RAG ALONE FAILS

Five Problems Knowledge Graphs Solve

We have shipped GraphRAG into financial services, pharma, legal, and manufacturing. These five failure modes show up every time the data has structure that matters.

Vector-Only RAG Misses Relationships

Cosine similarity finds related chunks but cannot traverse 'customer → account → contract → supplier' chains

Entity Duplication Across Source Systems

The same vendor exists as 11 different records across Salesforce, NetSuite, Coupa, and Jira

Multi-Hop Questions Take Days

Questions like 'which open Jira issues touch services owned by teams reporting to VP-X?' need 4 joins across 3 systems

LLM Answers Without Citations Are Unsafe

Generative answers cannot be audited back to source nodes — compliance, legal, and risk teams won't approve

Schema Sprawl in Heterogeneous Data

Confluence, SharePoint, Notion, Slack, Salesforce, GitHub, Jira — each with its own object model and IDs

Vector-Only RAG Misses Relationships

The Failure Mode

Cosine similarity finds related chunks but cannot traverse 'customer → account → contract → supplier' chains

Business Impact

Answers look plausible but skip the connective tissue that drives real decisions

Real Cost

Analysts re-do retrieval manually across 6-8 source systems per question

Engineering note: none of these are solved by adding more chunks to a vector store. They require explicit edges, resolved entities, and traversal.

THE STACK

Six Capabilities,Production-Hardened Across 50+ Projects

Every component is named, replaceable, and observable. No black-box vendor lock-in.

Polyglot Graph Store

Neo4j AuraDB for general workloads, Amazon Neptune for AWS-native deployments, TigerGraph for deep traversals on billion-edge graphs, Memgraph for streaming analytics. We pick per workload.

Entity Resolution at 95% Precision

Two-stage resolution — LSH blocking, then a classifier combining string similarity, structural graph features, and Claude reasoning for ambiguous cases. 95% precision at 92% recall on heterogeneous data.

Kafka-Based Streaming Ingest

Change-data-capture from Salesforce, Jira, GitHub, ServiceNow, and SQL sources via Kafka or Airbyte. The graph stays fresh incrementally — no full nightly rebuilds, no stale traversals.

GraphRAG Query Layer

LangChain GraphCypherQAChain translates natural language to Cypher, executes against the graph, then feeds structured results plus hybrid Qdrant vector hits into Anthropic Claude for cited reasoning.

Pydantic-Enforced Schema

Every entity type, relation, and LLM output is validated against Pydantic models. Schema drift fails loudly in CI, not silently in production. Audit-grade citations on every answer.

Datadog Query Observability

p50/p95/p99 latency per query type, cache hit rates, Cypher slow-query traces, embedding-call cost. We tune the schema and indexes until SLOs hold under production load.

ARCHITECTURE

The GraphRAG Pipeline, End to End

Seven stages from raw source-system event to cited natural-language answer. Each stage is independently observable and replaceable.

Ingest

Kafka streams change-data-capture events from Confluence, SharePoint, Notion, Slack, Salesforce, Google Workspace, GitHub, Jira, ServiceNow.

Kafka · Airbyte · Debezium
1

Entity Extraction

Hybrid NER pipeline — spaCy for high-volume structured fields, Claude for long-form unstructured documents. Output validated against a Pydantic entity schema.

spaCy · Claude · Pydantic
2

Entity Resolution

LSH blocking narrows candidate pairs; a classifier (string similarity + structural features + Claude reasoning) merges duplicates. Low-confidence matches route to human review.

Relation Extraction

Typed edges extracted from text and structured joins. Provenance preserved — every edge cites its source record. Edges are versioned, not overwritten.

Graph Store

Loaded into Neo4j AuraDB, Amazon Neptune, or TigerGraph — chosen per workload. Indexes tuned for the top-20 query patterns identified during schema design.

GraphRAG Query

LangChain GraphCypherQAChain converts the user question to Cypher, executes, and fuses results with Qdrant hybrid retrieval before handing to Claude for reasoning.

Cited Response

Every answer carries citations back to source nodes and edges. Compliance, legal, and risk teams can audit any claim. Hallucination surface shrinks to near-zero.

USE CASES

Where GraphRAG Pays for Itself

Five industries where we have shipped graph systems that traverse millions of resolved entities daily.

Financial Services

KYC + AML Investigations

Resolve beneficial-owner networks across Salesforce CRM, transaction systems, and external watchlists. Multi-hop traversals surface indirect exposure that flat lookups miss.

A multi-family-office SaaS used the graph to compress KYC-refresh cycles from 6 weeks to 4 days per entity.

Pharma + Life Sciences

Drug-Target-Pathway Reasoning

Unify internal trial data with public ontologies (UniProt, Reactome) into one graph. Researchers ask multi-hop questions like 'which targets in our portfolio share pathways with approved oncology drugs?'

Discovery teams cut literature-triage time from 3 days to 30 minutes per hypothesis.

Legal

Case-Law Cross-Citation

Graph all internal matters, opinions, and external citations. Paralegals trace precedent chains, conflicting rulings, and judge-jurisdiction patterns in a single Cypher query.

A Fortune 500 legal department cut conflict-check time from 2 hours to 4 minutes per matter.

Engineering + Manufacturing

Parts-Supplier-Defect Networks

Link BOMs, supplier contracts, defect reports, and field-failure data. When a defect spikes, the graph instantly returns affected SKUs, customers, suppliers, and warranty exposure.

An industrial OEM reduced defect-blast-radius analysis from 5 days to 90 seconds.

Customer Success

Account-Contact-Deal Intelligence

Merge Salesforce, Slack message history, Gong calls, and product telemetry into a single customer graph. CSMs see every touchpoint, every champion, every blocker in one view.

A vertical SaaS lifted net retention by surfacing at-risk accounts 60 days earlier than the prior heuristic.

IMPLEMENTATION

From Workshop to Production in 14 Weeks

A predictable, phased delivery. No multi-quarter discovery exercises.

1
Weeks 1-6

Phase 1 — Schema + Ingestion

Workshop the top-20 questions the graph must answer. Design entity types, relation types, and provenance model. Stand up Kafka connectors to 3-5 source systems and load the first 1-10M entities.

2
Weeks 7-14

Phase 2 — GraphRAG Query Layer

Build the LangChain GraphCypherQAChain pipeline, hybrid Qdrant retrieval, and Claude reasoning. Stand up the eval harness with 200+ golden questions across the priority use-cases.

3
Weeks 15-18

Phase 3 — Production Hardening

Datadog observability, p95 latency tuning, cache layer, role-based access in Neo4j or Neptune, audit-log export, and cutover. Eval gates block any regression on the golden set.

4
Ongoing

Phase 4 — Expansion

Add remaining source systems via the same Kafka pattern. Layer in new entity types as new use-cases arrive. The schema and pipeline scale — new questions stop costing engineer-weeks.

FAQ

Engineering Questions, Engineering Answers

The questions that actually matter when scoping a graph project.

When relationships matter. Vector RAG retrieves semantically similar chunks but cannot answer multi-hop questions like 'which suppliers of parts in defective Model-X assemblies also serve our top-3 customers?' Knowledge graphs encode those edges explicitly. In our internal evals, GraphRAG on Neo4j AuraDB delivered a 4x improvement in answer quality versus vector-only RAG on relationship-heavy queries.
