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.

Data types​

Check what data types are supported by Memgraph.

Import data​

Memgraph offers painless import of data from CSV files or Cypher queries within a .cypherl format file.

Indexing​

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

Inspecting and optimizing queries​

Inspect the plan for executing a query, a pipeline of operations which will be performed on the database in order to yield the results for a given query, to gain insight into the execution of a query or get a detailed report on how the query's plan behaved.

Isolation levels​

Isolation is a property that defines how or when the changes made by one operation become visible to other users or systems. Check available options for Memgraph.

Metadata​

Bolt protocol specifies additional data (metadata) that can be sent along with the requested results. Find out how to access it.

Monitoring server​

Receive logs and runtime information from Memgraph in real-time via WebSocket connection.

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.

Server stats​

Get information about the running instance.

Streams​

Memgraph can connect to existing Kafka, Pulsar and Redpanda 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:

Triggers​

Memgraph enables running openCypher statements after a certain event happens during transaction execution, i.e., triggers.

Enterprise features​

Features available for the Enterprise edition of Memgraph.

Audit log​

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

Authentication and authorization​

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

Runtime settings​

Check the settings that can be modified during runtime.

Security - user privileges​

Memgraph comes with the option of granting, denying, or revoking a certain set of privileges to users or groups of users.
