Dremio connection

To access your data in Dremio, create a connection asset for it.

Dremio is an open data lake platform. It supports all the major third-party data sources.

Create a connection to Dremio

To create the connection asset, you need these connection details:

  • Username and password
  • Hostname: You can create a Dremio Cloud instance only in the European Union (EU) or the United States (US). Use sql.dremio.cloud for the US, and use sql.eu.dremio.cloud for the EU. Dremio Software can be hosted anywhere.
  • Port number: The default port for Dremio Cloud instances is 443 and for Dremio Software it is 31010.
  • Dremio Cloud Project ID: See Obtaining the ID of a Project.
  • SSL certificate:
    • Select Port is SSL-enabled if you provided Dremio Cloud Project ID.
    • Select Port is SSL-enabled and provide SSL Certificate if you want to connect to Dremio Software with SSL.

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Choose the method for creating a connection based on where you are in the platform
