Copy data from Greenplum using Azure Data Factory

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

Supported capabilities

You can copy data from Greenplum 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 the copy activity by using one of the following tools or SDKs. Select a link to go to a tutorial with 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 Greenplum connector.

Linked service properties

The following properties are supported for Greenplum linked service:

Property Description Required
type The type property must be set to: Greenplum Yes
connectionString An ODBC connection string to connect to Greenplum. 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": "GreenplumLinkedService",
    "properties": {
        "type": "Greenplum",
        "typeProperties": {
            "connectionString": {
                 "type": "SecureString",
                 "value": "HOST=<server>;PORT=<port>;DB=<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 Greenplum dataset.

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

Example

{
    "name": "GreenplumDataset",
    "properties": {
        "type": "GreenplumTable",
        "linkedServiceName": {
            "referenceName": "<Greenplum 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 Greenplum source.

GreenplumSource as source

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

Example:

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