Sigma supports using Starburst Galaxy, a SaaS distribution of Trino, to connect to a Snowflake, Databricks, BigQuery, or PostgreSQL data warehouse.

This document explains how to connect your Sigma organization to your [Starburst Galaxy](https://docs.starburst.io/introduction/choose-your-starburst-product.html#starburst-galaxy) cluster.

For information about Sigma feature compatibility with Starburst connections, see [Region, warehouse, and feature support](/docs/region-warehouse-and-feature-support).

## Requirements

* You must be assigned the **Admin** [account type](/docs/account-type-and-license-overview) or an account type with the **Manage connections** feature permission enabled.
* You need the credentials for a Starburst Galaxy service account with `Select from table` privilege for all tables that Sigma needs to access and the `Use cluster` privilege on the cluster.

## Create a Starburst connection

1. Click the user icon at the top right of your screen. The user icon is usually composed of your initials.

2. In the drop-down menu, select **Add connection**.

3. The **Add new connection** page appears.

4. In the **Connection details**, specify the following:

   |          |                                                                                           |
   | -------- | ----------------------------------------------------------------------------------------- |
   | **Name** | Enter a **Name** for the new connection. Sigma displays this name in the connection list. |
   | **Type** | Select **Starburst**.                                                                     |

5. In the **Connection Credentials** section, complete the fields:

|              |                                                                              |
| ------------ | ---------------------------------------------------------------------------- |
| **Host**     | The address of your Starburst Galaxy cluster as a URL or an IP address.      |
| **Port**     | The port through which Sigma can connect to your Starburst Galaxy cluster.   |
| **User**     | The username of the service account set up by your Starburst administrator.  |
| **Password** | The password for the service account set up by your Starburst administrator. |

6. (Optional) In the **Connection features** section, adjust the defaults if needed.

   |                        |                                                                                                                                                                                         |
   | ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   | **Connection timeout** | The time before timeout (or cancellation), in seconds, that Sigma waits for the query to return results.<br />The default is 120, or 2 minutes.<br />The maximum is 600, or 10 minutes. |
   | **Use friendly names** | This setting, which is on by default, makes column names from the data source more readable.<br />For example, a database column ORDER\_NUMBER appears as Order Number.                 |

7. After you specify all the parameters of the connection, click **Create**. Sigma displays a connection summary on the screen.
