Graphmind Graph Database

Graphmind is a high-performance, distributed graph database written in Rust with ~90% OpenCypher support, Redis protocol compatibility, and a built-in web visualizer. It combines property graph storage, vector search, graph algorithms, and natural language querying in a single binary.

From Source

git clone https://github.com/fab679/graphmind.git
cd graphmind
cd ui && npm install && npm run build && cd ..
cargo build --release
./target/release/graphmind

Quick Start

# Start the server (RESP on :6379, HTTP on :8080)
graphmind

# Open the web visualizer
open http://localhost:8080

Create data and query

redis-cli -p 6379

# Create nodes and relationships
GRAPH.QUERY default "CREATE (a:Person {name: 'Alice', age: 30})"
GRAPH.QUERY default "CREATE (b:Person {name: 'Bob', age: 25})"
GRAPH.QUERY default "MATCH (a:Person {name: 'Alice'}), (b:Person {name: 'Bob'}) CREATE (a)-[:KNOWS]->(b)"

# Query
GRAPH.QUERY default "MATCH (p:Person)-[:KNOWS]->(friend) RETURN p.name, friend.name"

Load demo data

curl -X POST http://localhost:8080/api/script \
  -H 'Content-Type: application/json' \
  --data-binary @scripts/social_network_demo.cypher

SDK Examples

Python

pip install graphmind

from graphmind import GraphmindClient

db = GraphmindClient.embedded()  # or .remote("localhost", 8080)

db.query("""
    CREATE (a:Person {name: 'Alice', age: 30});
    CREATE (b:Person {name: 'Bob', age: 25});
    MATCH (a:Person {name: 'Alice'}), (b:Person {name: 'Bob'})
    CREATE (a)-[:KNOWS]->(b)
""")

result = db.query_readonly("MATCH (n:Person) RETURN n.name, n.age")
print(result)

TypeScript

npm install graphmind-sdk

import { GraphmindClient } from 'graphmind-sdk';

const client = new GraphmindClient({ url: 'http://localhost:8080' });

await client.query(`
  CREATE (a:Person {name: "Alice", age: 30});
  CREATE (b:Person {name: "Bob", age: 25});
  MATCH (a:Person {name: "Alice"}), (b:Person {name: "Bob"})
  CREATE (a)-[:KNOWS]->(b)
`);

const result = await client.query('MATCH (n:Person) RETURN n.name, n.age');

Rust

[dependencies]
graphmind-sdk = "0.6.5"

use graphmind_sdk::EmbeddedClient;

let mut client = EmbeddedClient::new();
client.query("default", "
    CREATE (a:Person {name: 'Alice', age: 30});
    CREATE (b:Person {name: 'Bob', age: 25});
    MATCH (a:Person {name: 'Alice'}), (b:Person {name: 'Bob'})
    CREATE (a)-[:KNOWS]->(b)
")?;

let result = client.query_readonly("default", "MATCH (n:Person) RETURN n.name, n.age")?;

redis-cli / Any Redis Client

redis-cli -p 6379
> GRAPH.QUERY default "MATCH (n) RETURN labels(n), count(n)"

import redis
r = redis.Redis(port=6379)
r.execute_command('GRAPH.QUERY', 'default', 'MATCH (n:Person) RETURN n.name')

REST API

curl -X POST http://localhost:8080/api/query \
  -H 'Content-Type: application/json' \
  -d '{"query": "MATCH (n) RETURN n LIMIT 10"}'

Configuration

See dist/config.toml for a full config file example.
