Copy data from MariaDB using Azure Data Factory or Synapse Analytics

[!INCLUDEappliesto-adf-asa-md]

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 activities:

• Copy activity with supported source/sink matrix
• Lookup activity

You can copy data from 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.

This connector currently supports MariaDB of version 10.0 to 10.5.

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:

   Azure Data Factory

   Azure Synapse

   :::image type="content" source="media/doc-common-process/new-linked-service-synapse.png" alt-text="Screenshot of creating a new linked service with Azure Synapse UI.":::

2. Search for Maria and select the MariaDB connector.

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>"
            }
        }
    }
]
