Reference guide overview

The Memgraph reference guide contains the details of implemented features.

Backup#

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

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.

Configuration settings#

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

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.

Indexing#

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

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.

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:

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.

Streams#

Memgraph can connect to existing Kafka streams. The streams are using user-defined transformations to produce Cypher queries based on the received messages. To learn more about streams and transformations take a look at the following pages:

Temporal types#

Temporal data types store and manipulate time. To learn more, take a look at the overview page:

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.
