Copy data from Vertica using Azure Data Factory

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

Note

This article applies to version 2 of Data Factory, which is currently in preview. If you are using version 1 of the Data Factory service, which is generally available (GA), see Copy Activity in V1.

Supported capabilities

You can copy data from Vertica 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 create a pipeline with copy activity using .NET SDK, Python SDK, Azure PowerShell, REST API, or Azure Resource Manager template. See Copy activity tutorial for step-by-step instructions to create a pipeline with a copy activity.

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

Linked service properties

The following properties are supported for Vertica linked service:

Property Description Required
type The type property must be set to: Vertica Yes
connectionString An ODBC connection string to connect to Vertica. Mark this field as a SecureString to store it securely in Data Factory, or reference a secret stored in Azure Key Vault. Yes
connectVia The Integration Runtime to be used to connect to the data store. You can use Self-hosted Integration Runtime or Azure Integration Runtime (if your data store is publicly accessible). If not specified, it uses the default Azure Integration Runtime. No

Example:

{
    "name": "VerticaLinkedService",
    "properties": {
        "type": "Vertica",
        "typeProperties": {
            "connectionString": {
                 "type": "SecureString",
                 "value": "Server=<server>;Port=<port>;Database=<database>;UID=<user name>;PWD=<password>"
            }
        },
        "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 Vertica dataset.

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

Example

{
    "name": "VerticaDataset",
    "properties": {
        "type": "VerticaTable",
        "linkedServiceName": {
            "referenceName": "<Vertica 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 Vertica source.

Vertica as source

To copy data from Vertica, set the source type in the copy activity to VerticaSource. 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: VerticaSource Yes
query Use the custom SQL query to read data. For example: "SELECT * FROM MyTable". Yes

Example:

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