How-to guides overview

Articles within this section serve as a cookbook for getting things done as fast as possible. These articles tend to provide a step-by-step guide on using certain Memgraph features or solving a particular problem.

Streams

Memgraph can connect to existing Kafka, Pulsar and Redpanda streams. The streams use 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:

• Kafka
  • Managing Kafka streams
  • Implement transformation modules
• Pulsar
  • Managing Pulsar streams
  • Implement transformation modules

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:

• Inspecting queries
• Profiling queries

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:

• Query modules

Replication

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

• Replication

Backup

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

• How to create a backup?

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:

• User privileges (Enterprise)

Authentication and authorization

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

• Authentication and authorization (Enterprise)

Triggers

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