Graph
RedisGraph is a queryable graph database built on Redis.
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
Commands
See Graph commands for a list of graph commands that are supported in Redis Enterprise.
Clients
For a list of available RedisGraph clients, see RedisGraph client libraries.
Configuration
See Configuration parameters for the complete list of RedisGraph configuration parameters.
To learn which configuration parameters are supported in Redis Enterprise, see Graph configuration compatibility with Redis Enterprise.
Design
For an overview of RedisGraph's design, see RedisGraph: A High Performance In-Memory Graph Database.
Client specification
RedisGraph client libraries should follow the Technical specification for writing RedisGraph client libraries.
Result set structure
RedisGraph result set structure describes the format RedisGraph uses to print data when using redis-cli.
GRAPH.BULK endpoint
You can import new graphs from CSV files using redisgraph-bulk-loader.
See the GRAPH.BULK implementation details for more information.
Data types
RedisGraph supports a number of distinct data types, including:
