RedisGraph is the fastest graph database that processes complex graph operations in real time, 10x – 600x faster than any other graph database. Show how your data is connected through multiple visualization integrations including RedisInsight, Linkurious, and Graphileon. Query graphs using the industry-standard Cypher query language and easily use graph capabilities from application code.
The 'redisgraph-py' is a package that allows querying Graph data in a Redis database that is extended with the RedisGraph module. The package extends redisgraph-py's interface with RedisGraph's API
Follow the steps below to get started with RedisGraph with Python:
Let us comment out the last line. Try to query Graph data over over RedisInsight.
Run the RedisInsight container. The easiest way is to run the following command:
Next, point your browser to http://localhost:8001.
You can use the limit clause to limit the number of records returned by a query:
MATCH (n) RETURN n LIMIT 1
MATCH (n) RETURN n
Redis is phasing out RedisGraph. This blog post explains the motivation behind this decision and the implications for existing Redis customers and community members.
End of support is scheduled for January 31, 2025.
