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
• dbt Integration

Requirements

Python Requirements

To run the MariaDB ingestion, you will need to install:

pip3 install "openmetadata-ingestion[mariadb]"

Metadata Ingestion

All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to MariaDB.

In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following JSON Schema

1. Define the YAML Config

{% codePreview %}

{% codeInfoContainer %}

Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

username: Specify the User to connect to MariaDB. It should have enough privileges to read all the metadata.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

password: Password to connect to MariaDB.

{% /codeInfo %}

{% codeInfo srNumber=3 %}

hostPort: Enter the fully qualified hostname and port number for your MariaDB deployment in the Host and Port field.

{% /codeInfo %}

{% codeInfo srNumber=4 %}

databaseName: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

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.

Advanced Configuration

{% codeInfo srNumber=6 %}

Connection Options (Optional): Enter the details for any additional connection options that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}

{% codeInfo srNumber=7 %}

Connection Arguments (Optional): Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

• In case you are using Single-Sign-On (SSO) for authentication, add the authenticator details in the Connection Arguments as a Key-Value pair as follows: "authenticator" : "sso_login_url"
