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

Supported capabilities

This MariaDB connector is supported for the following capabilities:

Supported capabilities IR
Copy activity (source/-) ① ②
Lookup activity ① ②

① Azure integration runtime ② Self-hosted integration runtime

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.

This connector currently supports MariaDB of version 10.0 to 10.5.

Prerequisites

If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.

If your data store is a managed cloud data service, you can use the Azure Integration Runtime. If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list.

You can also use the managed virtual network integration runtime feature in Azure Data Factory to access the on-premises network without installing and configuring a self-hosted integration runtime.

For more information about the network security mechanisms and options supported by Data Factory, see Data access strategies.

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 MariaDB using UI

Use the following steps to create a linked service to 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 MariaDB connector.

    Screenshot of the MariaDB connector.

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

Connector configuration details

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

Linked service properties

The following properties are supported for MariaDB linked service:

Property Description Required
type The type property must be set to: MariaDB Yes
connectionString An ODBC connection string to connect to MariaDB.
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. Learn more from Prerequisites section. If not specified, it uses the default Azure Integration Runtime. No

Example:

{
    "name": "MariaDBLinkedService",
    "properties": {
        "type": "MariaDB",
        "typeProperties": {
            "connectionString": "Server=<host>;Port=<port>;Database=<database>;UID=<user name>;PWD=<password>"
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}

Example: store password in Azure Key Vault

{
    "name": "MariaDBLinkedService",
    "properties": {
        "type": "MariaDB",
        "typeProperties": {
            "connectionString": "Server=<host>;Port=<port>;Database=<database>;UID=<user name>;",
            "pwd": { 
                "type": "AzureKeyVaultSecret", 
                "store": { 
                    "referenceName": "<Azure Key Vault linked service name>", 
                    "type": "LinkedServiceReference" 
                }, 
                "secretName": "<secretName>" 
            }
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}

Dataset properties

For a full list of sections and properties available for defining datasets, see the datasets article. This section provides a list of properties supported by MariaDB dataset.

To copy data from MariaDB, set the type property of the dataset to MariaDBTable. There is no additional type-specific property in this type of dataset.

Example

{
    "name": "MariaDBDataset",
    "properties": {
        "type": "MariaDBTable",
        "typeProperties": {},
        "schema": [],
        "linkedServiceName": {
            "referenceName": "<MariaDB linked service name>",
            "type": "LinkedServiceReference"
        }
    }
}

Copy activity properties

For a full list of sections and properties available for defining activities, see the Pipelines article. This section provides a list of properties supported by MariaDB source.

MariaDB as source

To copy data from MariaDB, set the source type in the copy activity to MariaDBSource. The following properties are supported in the copy activity source section:

Property Description Required
type The type property of the copy activity source must be set to: MariaDBSource Yes
query Use the custom SQL query to read data. For example: "SELECT * FROM MyTable". No (if "tableName" in dataset is specified)

Example:

"activities":[
    {
        "name": "CopyFromMariaDB",
        "type": "Copy",
        "inputs": [
            {
                "referenceName": "<MariaDB input dataset name>",
                "type": "DatasetReference"
            }
        ],
        "outputs": [
            {
                "referenceName": "<output dataset name>",
                "type": "DatasetReference"
            }
        ],
        "typeProperties": {
            "source": {
                "type": "MariaDBSource",
                "query": "SELECT * FROM MyTable"
            },
            "sink": {
                "type": "<sink type>"
            }
        }
    }
]
