Copy data from Azure Database for MariaDB using Azure Data Factory

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

Supported capabilities

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

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.

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

Getting started

You can use one of the following tools or SDKs to use the copy activity with a pipeline. Select a link for step-by-step instructions:

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

Linked service properties

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

Property Description Required
type The type property must be set to: AzureMariaDB Yes
connectionString A connection string to connect to Azure Database for MariaDB. You can find it from the Azure portal -> your Azure Database for MariaDB -> Connection strings -> ADO.NET one.
Mark this field as a SecureString to store it securely in Data Factory. You can also put password in Azure Key Vault and pull the pwd configuration out of the connection string. Refer to the following samples and Store credentials in Azure Key Vault article with more details.
Yes
connectVia The Integration Runtime to be used to connect to the data store. If not specified, it uses the default Azure Integration Runtime. No

Example:

{
    "name": "AzureDatabaseForMariaDBLinkedService",
    "properties": {
        "type": "AzureMariaDB",
        "typeProperties": {
            "connectionString": {
                "type": "SecureString",
                "value": "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": {
                 "type": "SecureString",
                 "value": "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"
        }
    }
}

    "properties": {
        "type": "AzureMariaDBTable",
        "typeProperties": {},
        "schema": [],
        "linkedServiceName": {
            "referenceName": "<Azure Database for MariaDB linked service name>",
            "type": "LinkedServiceReference"
        }
    }
}
