MariaDB connection

MariaDB connection

To access your data in MariaDB, create a connection asset for it.

MariaDB is an open source relational database. You can use the MariaDB connection to connect to either a MariaDB server or to a Microsoft Azure Database for MariaDB service in the cloud.

Supported versions

  • MariaDB server: 10.5.5
  • Microsoft Azure Database for MariaDB: 10.3

Create a connection to MariaDB

To create the connection asset, you need these connection details:

  • Database name
  • Hostname or IP address
  • Port number
  • Username and password
  • SSL certificate (if required by the database server)

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Choose the method for creating a connection based on where you are in the platform

In a project
Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.
In a catalog
Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space
Click Add to space > Connection. See Adding connections to a deployment space.
In the Platform assets catalog
Click New connection. See Adding platform connections.

Next step: Add data assets from the connection
