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](#requirements)
- [Metadata Ingestion](#metadata-ingestion)
- [Data Profiler](/connectors/ingestion/workflows/profiler)
- [Data Quality](/connectors/ingestion/workflows/data-quality)
- [dbt Integration](/connectors/ingestion/workflows/dbt)

## 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.

```SQL
-- 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](/connectors/ingestion/workflows/profiler) and data quality tests [here](/connectors/ingestion/workflows/data-quality).

## 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.
