RuVector

A distributed vector database that learns. Store embeddings, query with Cypher, scale horizontally with Raft consensus, and let the index improve itself through Graph Neural Networks.

npx ruvector

All-in-One Package: The core ruvector package includes everything — vector search, graph queries, GNN layers, distributed clustering, AI routing, and WASM support. No additional packages needed.

What Problem Does RuVector Solve?

Traditional vector databases just store and search. When you ask "find similar items," they return results but never get smarter. They don't scale horizontally. They can't route AI requests intelligently.

RuVector is different:

1. Store vectors like any vector DB (embeddings from OpenAI, Cohere, etc.)
2. Query with Cypher like Neo4j (MATCH (a)-[:SIMILAR]->(b) RETURN b)
3. The index learns — GNN layers make search results improve over time
4. Scale horizontally — Raft consensus, multi-master replication, auto-sharding
5. Route AI requests — Semantic routing and FastGRNN neural inference for LLM optimization
6. Compress automatically — 2-32x memory reduction with adaptive tiered compression
7. Run anywhere — Node.js, browser (WASM), HTTP server, or native Rust

Think of it as: Pinecone + Neo4j + PyTorch + etcd in one Rust package.

How the GNN Works

Traditional vector search:

Query → HNSW Index → Top K Results

RuVector with GNN:

Query → HNSW Index → GNN Layer → Enhanced Results
                ↑                      │
                └──── learns from ─────┘

The GNN layer:

1. Takes your query and its nearest neighbors
2. Applies multi-head attention to weigh which neighbors matter
3. Updates representations based on graph structure
4. Returns better-ranked results

Over time, frequently-accessed paths get reinforced, making common queries faster and more accurate.

Compression Tiers

The architecture adapts to your data. Hot paths get full precision and maximum compute. Cold paths compress automatically and throttle resources. Recent data stays crystal clear; historical data optimizes itself in the background.

Think of it like your computer's memory hierarchy—frequently accessed data lives in fast cache, while older files move to slower, denser storage. RuVector does this automatically for your vectors:

Access Frequency	Format	Compression	What Happens
Hot (>80%)	f32	1x	Full precision, instant retrieval
Warm (40-80%)	f16	2x	Slight compression, imperceptible latency
Cool (10-40%)	PQ8	8x	Smart quantization, ~1ms overhead
Cold (1-10%)	PQ4	16x	Heavy compression, still fast search
Archive (<1%)	Binary	32x	Maximum density, batch retrieval

No configuration needed. RuVector tracks access patterns and automatically promotes/demotes vectors between tiers. Your hot data stays fast; your cold data shrinks.

Use Cases

RAG (Retrieval-Augmented Generation)

const context = ruvector.search(questionEmbedding, 5);
const prompt = `Context: ${context.join('\n')}\n\nQuestion: ${question}`;

Recommendation Systems

MATCH (user:User)-[:VIEWED]->(item:Product)
MATCH (item)-[:SIMILAR_TO]->(rec:Product)
RETURN rec ORDER BY rec.score DESC LIMIT 10

Knowledge Graphs

MATCH (concept:Concept)-[:RELATES_TO*1..3]->(related)
RETURN related
