Vertica connection

This document will guide you on how to configure and create a Vertica connection in Data Integration.
Follow the next steps in order to create a successful connection.

Create a Data Integration database user

In order to extract data, it's recommended to create a new user in the database for Data Integration:

CREATE USER [<Data_Integration Username>] IDENTIFIED BY '<myPassword>'

Permit the new user you've created above, to the database:

GRANT USAGE ON SCHEMA '<database>' to [<Data_Integration Username>];

More permissions can be found here. We only need a grant of SELECT privileges, so GRANT VIEW is enough.

You can also explicitly give permission to one of your schemas: GRANT SELECT ON SCHEMA <database>.<schema> to [<Data_Integration Username>];

GRANT SELECT ON SCHEMA '<database>.<schema>' to [<Data_Integration Username>];

Connect to Vertica in Data Integration

To connect to your Vertica, you must first set up your database credentials.

Define your Vertica connection

  1. In Data Integration’s main menu, Go to Connections- >Create Connection, or create your new connection in the source, pressing Create New Connection in the Rivers wizard.
  2. In the pop-out window, define your credential details: It is advised to whitelisting Data Integration IPs on your Database Firewall. Whitelist our IPs
  3. Define your Host, Port, Database, Username, and Password.

Connecting from Vertica

Using SSH Tunneling in order to connect your on-premise database server with Data Integration.

Using a hybrid method of data processing, Data Integration can connect to on-prem servers. We recommend the use of an SSH Tunneling Method.

To use the SSH Tunneling via Data Integration, configure your SSH Tunnel server in your network. This server will have the ability to get SSH connections from Data Integration IPs and will

be able to connect to your database server via the internal IP or address. Data Integration connects to that SSH server using a private key.

After you've configured SSH tunneling, you can set it up in the Data Integration Connection: Under the SSH Options section, in the Vertica Connection Pop-up, you can define the following:

  • SSH Hostname
  • SSH Port (in most of the connection, that should be 22)
  • The Username Data Integration should connect via the SSH to the server
  • Password (optional)
  • SSH Pem Key (Recommended)
  • And if you have also a Pem Password for that key file.
