SFTP Connections


This feature may not be available in all product editions. For more information on available features, see Compare Editions.

You can create connections to SFTP servers to upload your datasets to the Trifacta Application.

Linux- and Windows-based SFTP servers are supported.

Jobs can be executed from SFTP sources on the following running environments:

  • Trifacta Photon

  • Spark on EMR

Read: Supported

Write: Not supported


  • Read-only connection

  • Files and folders with spaces or special characters in them cannot be used. For example, a file or folder on the SFTP server with a hashtag (#) in it cannot be used for data.

    • Files and folders whose names begin with underscore (_) are not visible.

  • Ingest of over 500 files through SFTP at one time is not supported.

  • For private SFTP servers, you cannot run jobs on Spark. These jobs must be run using Trifacta Photon.

  • Through SFTP connections, you cannot run jobs on Avro or Parquet files or on parameterized datasets, from file types that require conversion such as JSON, PDF, and Excel.

    • Single Excel files can be imported through SFTP.


  • Acquire user credentials to access the SFTP server. You can use username/password credentials or SSH keys. See below.

  • Verify that the credentials can access the proper locations on the server where your data is stored. Initial directory of the user account must be accessible.

SSH Keys

If preferred, you can use SSH keys to for authentication to the SFTP server.


SSH keys must be private RSA keys. If you have OpenSSH keys, you can use the ssh-keygen utility to convert them to private RSA keys.

Whitelist SFTP server

If your SFTP server is private, you must add the Trifacta's IP to the whitelist of IPs that are permitted to communicate with the server. For more information, please see the documentation that is provided with your software distribution.

Create Connection

Create through application

You can create a SFTP connection through the Trifacta Application.


  1. In the left nav bar, select the Connections icon. See Connections Page.

  2. In the Connections page, click Create Connection. See Create Connection Window.

  3. In the Create Connection window, click the SFTP connection card.

  4. Specify the properties for your SFTP server.




    The hostname of the FTP server to which you are connecting. Do not include any protocol identifier (sftp://).


    The port number to use to connect to the server. Default port number is 22.

    Credential Type

    Select one of the following:

    basic - authenticate via username and password

    SSH Key - authenticate via username and SSH key

    User Name

    The username to use to connect.


    (Basic credential type) The password associated with the username.

    SSH Key

    (SSH Key credential type) The SSH key that applies to the username.

    Click this button to test the connection that you have specified.

    Default Directory

    Absolute path on the SFTP server where users of the connection can begin browsing.

    Block Size (Bytes)

    Fetch size in bytes for each read from the SFTP server.


    Raising this value may increase speed of read operations. However, if it is raised too high, resources can become overwhelmed, and the read can fail.

    Connection Name

    The name of the connection as you want it to appear in the application.
