Prerequisites

Add a connection

  1. Go to [your source] > Connections and select Add Connection.

  2. In Connection type, select Dremio.

  3. Fill in the following:

    • Name: A meaningful name for your connection. Used to indicate the location of catalog items.

    • Description (Optional): A short description of the connection.

    • JDBC: An Arrow Flight SQL JDBC connection string pointing to the IP address or the URL where your Dremio instance can be reached. See JDBC connection string format.

JDBC connection string format

Dremio uses the Arrow Flight SQL JDBC driver. The expected syntax is as follows:

Username and password authentication
jdbc:arrow-flight-sql://server_name:32010/?useEncryption=true

The default Arrow Flight SQL port is 32010. TLS communication is enabled by default for Arrow Flight client applications. If your Dremio instance is not configured for encrypted communication, set useEncryption=false.

For more details about the connection string and supported properties, see Arrow Flight SQL JDBC driver in the Dremio documentation.

Add credentials

Only Username and password authentication is currently supported.

  1. Select Add Credentials.

  2. Fill in the following:

    • Name: Provide a clear name for this set of credentials.

    • Description (Optional): Explain what the credentials are used for or provide other useful information.

    • Username: The username for the Dremio account.

    • Password: The password for the Dremio account.

  3. To use this set of credentials by default when connecting to the data source, select Assign as default.

Always use the dedicated credential fields for authentication details such as passwords, secrets, and tokens. This ensures credentials are handled with the appropriate level of protection and reliably preserved across environments.
One set of credentials must be defined as default for each connection. Otherwise, DQ evaluation fails and previewing data in the catalog is not possible.

Next steps

Test and save your connection to complete setup.
