- If you haven't done so already, you must create and deploy an encryption key file for the Trifacta node to be shared by all relational connections. For more information, see Create Encryption Key File.
To create this connection:
- In the Import Data page, click the Plus sign. Then, select the Relational tab. Click the PostgreSQL card.
- You can also create connections through the Connections page.
