Reference guide overview

The Memgraph reference guide contains the details of implemented features.

Built-in graph algorithms​

Memgraph comes with custom-built algorithms that are implemented using C++: Depth-first search, Breadth-first search, Weighted shortest path, All shortest paths.

Configuration settings​

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

Data durability and backup​

Memgraph uses snapshots and WAL to ensure the durability of the stored data and it comes with a couple of queries that allow you to safely make a backup of these files.

Data types​

Check what data types are supported by Memgraph.

Deployment​

Deploy your application with Memgraph as a part of your Docker Compose file or use a Helm Chart to make Memgraph part of your Kubernetes cluster.

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.

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:

Transactions​

All Cypher queries are run within transactions. Check how to create explicit transaction to run multiple queries within one transaction, and isolation levels available in Memgraph.

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.
