Connection types

Connection types

Starting from Lab 2.16, Memgraph Lab supports three types of connections to your Memgraph instances:

  1. Connect to a standalone instance
  2. Connect to a main or replica instance
  3. Connect to a HA cluster with automatic failover

Connect to a standalone instance

This is the regular Bolt connection to a single Memgraph instance. You will need to define:

  • Host: Either localhost, 127.0.0.1, 0.0.0.0, or another appropriate address.
  • Port: Enter 7687, which Memgraph uses by default.
  • Logs Port: Default is 7444, the port for web socket logs.
  • Database Name: Leave empty unless connecting to a multi-tenant Memgraph instance.
  • Encrypted: Choose whether the connection is encrypted (SSL on or SSL off).

Connection color

You can choose a color for your connection. This color will be displayed below the status bar and titles to help distinguish between different environments when connecting to multiple Memgraph instances from the same Lab instance.

Coordinator instance

Standalone connections can also be used to connect to a Coordinator instance. When connecting to the Coordinator, the Lab UI changes to support only cluster management queries. You will see components like query execution, run history, query collections, and query sharing. The status bar will display the number of active and total coordinators and data instances instead of the number of nodes, relationships, and memory/disk metrics.

Connect to a main or replica instance

Connecting to a main or replica instance is similar to connecting to a standalone instance with an additional status bar difference upon successful connection: Replication status overview.

Replication status

If connected to a main instance, the status bar will display replication status, including the status of replicas and their system and data replication status. The status bar will also show that you are connected to the "Main" instance.

If connected to a replica, you will not see the replication status because replicas do not have the permission to display this information. The status bar will show that you are connected to the "Replica" instance.

Connect to an HA cluster with automatic failover

The HA cluster is an enterprise feature that supports automatic failover with a set of coordinators and data instances. Choose the "HA Cluster" connection type and input the Host and Port of any coordinator instance.

Once you are in, you can run queries and manage data similar to a standalone or main/replica instance connection.

Cluster status

When connected to the HA cluster, the status bar provides additional information about the cluster status, showing the status of each coordinator and data instance.
