# RuVector Research Summary

> Research conducted 2026-02-24 for makima improvement evaluation

## Overview

RuVector is a high-performance vector database with graph intelligence capabilities, self-learning DAG execution, and distributed consensus. It combines vector search, graph neural networks, and reinforcement learning into a unified platform.

**Repository**: https://github.com/ruvnet/ruvector

## Architecture

### Core Components
- **HNSW Indexing**: Hierarchical Navigable Small World for approximate nearest neighbor search
- **GNN Layers**: Graph Neural Networks for query reranking and path optimization
- **ReasoningBank**: Trajectory learning with verdict judgment
- **SONA**: Self-Optimizing Neural Architecture for runtime adaptation
- **Raft Consensus**: Distributed coordination and fault tolerance

### Key Performance
- 61µs p50 latency for vector queries
- 2-32x memory reduction via adaptive compression
- SIMD acceleration (AVX2/AVX-512/NEON)
- 10-50x burst scaling for traffic spikes

## Graph Database Capabilities

### Cypher Query Support
- Neo4j-compatible Cypher syntax: `MATCH (a)-[:SIMILAR]->(b)`
- Hyperedge support connecting 3+ nodes simultaneously
- Combines relationship-based search with vector similarity
- Enables "semantic + structured search"

### Graph Intelligence
- PageRank computation
- Spectral clustering
- Community detection
- Multi-head attention for neighbor importance weighting

## Self-Learning DAG Execution

This is the most relevant capability for makima:

### Architecture
- **Automatic query optimization** through continuous learning
- **7 attention mechanisms** dynamically select optimal execution strategies
- **50-80% latency reduction** over time as patterns are learned
- **MinCut control** triggers automatic strategy switching above tension thresholds

### Learning Cycle
1. **Topological analysis** of DAG structure
2. **Causal cone evaluation** for dependency impact
3. **Critical path identification** and optimization
4. **Trajectory learning** via ReasoningBank
5. **Adaptive routing** based on learned patterns

## Self-Learning Mechanisms

### SONA (Self-Optimizing Neural Architecture)
- Two-tier LoRA + EWC++ + ReasoningBank
- <1ms adaptive learning per request
- 55% quality improvement over baseline
- Per-request micro-LoRA adaptation (rank 1-2)

### GNN-Based Optimization
- Multi-head attention weights neighbor importance
- Updates representations based on graph structure
- Reinforces frequently-accessed paths
- "The more you search, the better results get"

### Q-Learning Integration
- Neural patterns learn optimal routing
- HNSW memory integration for fast retrieval
- Dynamic index topology optimization

## Memory Management

### Efficiency Mechanisms
- **Adaptive tiered compression**: 2-32x memory reduction
- **SIMD-optimized SpMV**: Sparse matrix-vector multiplication
- **Arena allocators**: Bounds-check elimination
- **COW branching**: Cluster-level copy-on-write (1M vectors, ~2.5MB per edit)

### RVF Cognitive Container
- Git-like branching of vector datasets
- DNA-style lineage tracking parent/child derivation
- Cryptographic verification of data integrity
- Progressive indexing through layered construction

## Fault Tolerance

- **Raft consensus**: Leader election and log replication
- **Multi-master replication**: Vector clock conflict resolution
- **Geo-distributed sync**: Cross-region high availability
- **Snapshot/backup**: Point-in-time recovery
- **Post-quantum signatures**: ML-DSA-65 and Ed25519 on every segment

## Advanced Features

### 46 Attention Mechanisms
Categories: standard (dot-product, multi-head, Flash), graph-specific (RoPE, edge-featured, dual-space), efficiency (sparse, cross-attention, neighborhood), specialized (mincut-gated transformer with 50% compute reduction).

### Adaptive Routing
- "Tiny Dancer" FastGRNN neural inference
- 90% semantic routing accuracy
- Hybrid keyword-first + embedding fallback strategy

### Additional Capabilities
- Local LLM execution (ruvllm with GGUF models)
- Topological data analysis via persistent homology
- Post-quantum cryptography
- eBPF kernel acceleration
- 5.5KB WASM runtime for browser deployment
