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

Supported capabilities

This Vertica connector is supported for the following capabilities:

Supported capabilities	IR
Copy activity (source/-)	① (only for version 1.0) ②
Lookup activity	① (only for version 1.0) 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.

For version 2.0 (Preview), you need to install a Vertica ODBC driver manually. For version 1.0, the service provides a built-in driver to enable connectivity, therefore you don't need to manually install any driver.

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 you use the version 2.0 (Preview), your self-hosted integration runtime version should be 5.44.8984.1 or above.

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

For version 1.0

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 allowlist.

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.

Install Vertica ODBC driver for the version 2.0 (Preview)

To use Vertica connector with version 2.0 (Preview), install the Vertica ODBC driver on the machine running the self-hosted Integration runtime by following these steps:

Download the Vertica client setup for ODBC driver from Client Drivers | OpenText™ Vertica™. Take Windows system setup as an example:
Open the downloaded .exe to begin the installation process. 
Select ODBC driver under Vertica Component List, then select Next to start the installation.
After the installation process is successfully completed, you can go to Start -> ODBC Data Source Administrator to confirm the successful installation.

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.

Create a linked service to Vertica using UI

Use the following steps to create a linked service to Vertica in the Azure portal UI.

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
Search for Vertica and select the Vertica connector.
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 Vertica connector.
