GrafeoDB

Embeddable graph database built in pure Rust. Dual data models (LPG + RDF), six query languages, HNSW vector search, MVCC transactions. Fastest graph database tested on the LDBC Social Network Benchmark in both embedded and server configurations, with a low memory footprint. Now in beta.

Why Grafeo?

  • 6 query languages: GQL (ISO), Cypher, Gremlin, GraphQL, SPARQL, SQL/PGQ. Use what you know or want to learn.
  • LPG + RDF in one engine: Property graphs and triples with optimized storage for each.
  • Vector search: HNSW indexes with scalar, binary, and product quantization. SIMD-accelerated.
  • Embeddable: Link as a library (Rust, Python, Node.js, WASM) or run as a server. No external processes.
  • Fast and lean: Fastest graph database tested on LDBC SNB in both embedded and server modes, with a lower memory footprint than other in-memory databases. Push-based vectorized execution, morsel-driven parallelism, columnar storage with zone maps. Benchmarked with graph-bench and ann-benchmarks.

Quick Start

import grafeo

db = grafeo.GrafeoDB()

# Build a graph
db.execute("INSERT (:Person {name: 'Alice', age: 30})-[:KNOWS {since: 2020}]->(:Person {name: 'Bob', age: 25})")
db.execute("INSERT (:Person {name: 'Bob'})-[:KNOWS]->(:Person {name: 'Carol', age: 28})")

# Traverse it
for row in db.execute("""
    MATCH (p:Person)-[:KNOWS]->(friend)-[:KNOWS]->(fof)
    WHERE fof <> p
    RETURN p.name, fof.name AS friend_of_friend
"""):
    print(row)
