In this section, we provide guides and references to use the MariaDB connector.

Configure and schedule MariaDB metadata and profiler workflows from the OpenMetadata UI:

• Requirements
• Metadata Ingestion
• Data Profiler
• Data Quality
• dbt Integration
• Troubleshooting

Requirements

Metadata

To extract metadata the user used in the connection needs to have access to the INFORMATION_SCHEMA. By default a user can see only the rows in the INFORMATION_SCHEMA that correspond to objects for which the user has the proper access privileges.

-- Create user. More details https://mariadb.com/kb/en/create-user/
CREATE USER <username>[@<hostName>] IDENTIFIED BY '<password>';

-- Grant select on a database
GRANT SELECT ON world.* TO '<username>';

-- Grant select on a database
GRANT SELECT ON world.* TO '<username>';

-- Grant select on a specific object
GRANT SELECT ON world.hello TO '<username>';

Profiler & Data Quality

Executing the profiler workflow or data quality tests, will require the user to have SELECT permission on the tables/schemas where the profiler/tests will be executed. More information on the profiler workflow setup can be found here and data quality tests here.

Metadata Ingestion

Connection Details

• Username: Specify the User to connect to MariaDB. It should have enough privileges to read all the metadata.
• Password: Password to connect to MariaDB.
• Host and Port: Enter the fully qualified hostname and port number for your MariaDB deployment in the Host and Port field.
• databaseName: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.
• databaseSchema: databaseSchema of the data source. This is optional parameter, if you would like to restrict the metadata reading to a single databaseSchema. When left blank, OpenMetadata Ingestion attempts to scan all the databaseSchema.
