Important

This connector will be deprecated on December 31, 2024. Please migrate to Azure Database for MySQL connector by that date. You can also refer to this article for the Azure Database for MariaDB migration guidance.

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.

Supported capabilities

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

Supported capabilities IR Managed private endpoint
Copy activity (source/-) ① ② ✓
Lookup activity ① ② ✓

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.

Getting started

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

Create a linked service to Azure Database for MariaDB using UI

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:

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

Connector configuration details

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.
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": "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": {
