RedisGraph is the first queryable Property Graph database to use sparse matrices to represent the adjacency matrix in graphs and linear algebra to query the graph.

Primary features:

  • Based on the Property Graph Model
    • Nodes (vertices) and Relationships (edges) that may have attributes
    • Nodes that can be labeled
    • Relationships have a relationship type
  • Graphs represented as sparse adjacency matrices
  • Cypher as query language
    • Cypher queries translated into linear algebra expressions

Developing with RedisGraph

Before using RedisGraph, you should familiarize yourself with its commands and syntax as detailed in the commands reference.

After you load RedisGraph, you can interact with it using redis-cli.

Here we'll quickly create a small graph representing a subset of motorcycle riders and teams taking part in the MotoGP league. Once created, we'll start querying our data.

With redis-cli

$ redis-cli
127.0.0.1:6379> GRAPH.QUERY MotoGP "CREATE (:Rider {name:'Valentino Rossi'})-[:rides]->(:Team {name:'Yamaha'}), (:Rider {name:'Dani Pedrosa'})-[:rides]->(:Team {name:'Honda'}), (:Rider {name:'Andrea Dovizioso'})-[:rides]->(:Team {name:'Ducati'})"
1) (empty list or set)
2) 1) Labels added: 2
   2) Nodes created: 6
   3) Properties set: 6
   4) Relationships created: 3
   5) "Query internal execution time: 0.399000 milliseconds"

Now that our MotoGP graph is created, we can start asking questions. For example: Who's riding for team Yamaha?

127.0.0.1:6379> GRAPH.QUERY MotoGP "MATCH (r:Rider)-[:rides]->(t:Team) WHERE t.name = 'Yamaha' RETURN r,t"
1) 1) 1) "r.name"
      2) "t.name"
   2) 1) "Valentino Rossi"
      2) "Yamaha"
2) 1) "Query internal execution time: 0.122000 milliseconds"

How many riders represent team Ducati?

127.0.0.1:6379> GRAPH.QUERY MotoGP "MATCH (r:Rider)-[:rides]->(t:Team {name:'Ducati'}) RETURN count(r)"
1) 1) 1) "count(r)"
   2) 1) "1.000000"
2) 1) "Query internal execution time: 0.129000 milliseconds"

With any other client

You can interact with RedisGraph using your client's ability to send raw Redis commands. The exact method for doing that depends on your client of choice.

Python example

This code snippet shows how to use RedisGraph with raw Redis commands from Python using redis-py:

import redis

r = redis.StrictRedis()
reply = r.execute_command('GRAPH.QUERY', 'social', "CREATE (:person {name:'roi', age:33, gender:'male', status:'married')")
