Resources#

Installation#

Visit the Installation guide to find out more about the installation process.

Querying the database#

Memgraph uses the openCypher query language. Learn how to query Memgraph:

Importing data#

Data can be imported from CSV files using the CSV Import Tool or by using openCypher queries. Take a look at the Import data guide.

Query modules#

Memgraph supports extending the query language with user-written procedures. These procedures are grouped into modules, which can then be loaded either on startup or later on. To learn more about query modules take a look at the following guides:

Inspect and profile Cypher queries#

Memgraph also enables you to inspect and profile the execution of a query and get a detailed report on how the query's plan behaved. Take a look at the guides:

NetworkX#

Memgraph includes a set of Python query modules based on the NetworkX library of algorithms. You can find more information about all the available algorithms in the NetworkX Reference guide.

Machine learning#

Memgraph TensorFlow op wraps the high-performance Memgraph client for use with TensorFlow, allowing natural data transfer between Memgraph and TensorFlow at any point of the model. If you are interested in using Memgraph for machine learning purposes take a look at:

Replication#

Memgraph supports replication and the following guide demonstrates how to create a simple cluster of nodes running Memgraph instances:

Backup#

Memgraph comes with a couple of queries that allow you to safely make a backup of the files containing its data:

User privileges#

Memgraph comes with the option of granting, denying, or revoking a certain set of privileges to users or groups of users. To learn more visit:

Authentication and authorization#

Memgraph supports authentication and (optional) authorization using a custom-built external auth module. To learn more visit:

Audit log#

Memgraph supports all query audit logging. When enabled, the audit log contains records of all queries executed on the database.
