Reference guide overview

Memgraph supports most of the commonly used constructs of the language. The reference guide contains the details of implemented features. Additionally, not yet supported features of the language are listed.

Cypher query language

Cypher is a declarative graph query language that allows for expressive and efficient data querying in a property graph. It aims to be intuitive and easy to learn while providing a powerful interface for working with graph-based data.

Configuration settings

Memgraph can be configured by editing the Memgraph configuration file or by including another configuration file.

Indexing

An index stores additional information on certain types of data, so that retrieving said data becomes more efficient.

Built-in graph algorithms

Memgraph comes with custom-built algorithms that are implemented using C++: Filtering variable-length paths, Breadth-first search, and Weighted shortest path.

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.

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 NetxorkX 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.

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.

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.

Replication

Memgraph comes with a couple of queries that allow you to safely make a backup of the files containing its data. Memgraph supports replication and allows you to create a cluster of nodes running Memgraph instances.
