Copy data from Azure Database for MariaDB using Azure Data Factory or Synapse Analytics

APPLIES TO: Azure Data Factory Azure Synapse Analytics

This article outlines how to use the Copy Activity in an Azure Data Factory or Synapse Analytics pipeline to copy data from Azure Database for MariaDB. It builds on the copy activity overview article that presents a general overview of copy activity.

This Azure Database for MariaDB connector is supported for the following capabilities:

① Azure integration runtime ② Self-hosted integration runtime

You can copy data from Azure Database for MariaDB to any supported sink data store. For a list of data stores that are supported as sources/sinks by the copy activity, see the Supported data stores table.

The service provides a built-in driver to enable connectivity, therefore you don't need to manually install any driver using this connector.

To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:

• The Copy Data tool
• The Azure portal
• The .NET SDK
• The Python SDK
• Azure PowerShell
• The REST API
• The Azure Resource Manager template

Use the following steps to create a linked service to Azure Database for MariaDB in the Azure portal UI.

1. Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New:

   • Azure Data Factory
   • Azure Synapse

   

2. Search for Maria and select the Azure Database for MariaDB connector.

   

3. Configure the service details, test the connection, and create the new linked service.

   

The following sections provide details about properties that are used to define Data Factory entities specific to Azure Database for MariaDB connector.

The following properties are supported for Azure Database for MariaDB linked service:

Example:

{
    "name": "AzureDatabaseForMariaDBLinkedService",
    "properties": {
        "type": "AzureMariaDB",
        "typeProperties": {
            "connectionString": "Server={your_server}.mariadb.database.azure.com; Port=3306; Database={your_database}; Uid={your_user}@{your_server}; Pwd={your_password}; SslMode=Preferred;"
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}

Example: store password in Azure Key Vault

{
    "name": "AzureDatabaseForMariaDBLinkedService",
    "properties": {
        "type": "AzureMariaDB",
        "typeProperties": {
            "connectionString": "Server={your_server}.mariadb.database.azure.com; Port=3306; Database={your_database}; Uid={your_user}@{your_server}; SslMode=Preferred;",
            "pwd": { 
                "type": "AzureKeyVaultSecret", 
                "store": { 
                    "referenceName": "<Azure Key Vault linked service name>", 
                    "type": "LinkedServiceReference" 
                }, 
                "secretName": "<secretName>" 
            }
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}
