In this guide, you’ll learn how to connect your StarRocks database to Omni.

​
Requirements

To follow the steps in this guide, you’ll need:
  • Organization Admin permissions in Omni
  • Permissions in StarRocks that allow you to create database users

​
Setup

1

Create a database user for Omni

In your StarRocks database, run the following command to create a database user for Omni:
Create Omni user
CREATE USER omni IDENTIFIED WITH mysql_native_password BY '<password>';
Next, run the following command to grant the Omni user access to the database:
Grant SELECT permissions to Omni user
GRANT SELECT ON <database_name>.* TO 'omni'@'%';
2

Allowlist Omni's IP addresses

If access to the StarRocks database is limited by IP address, you’ll need to add Omni’s IPs to the allowlist before you create the database connection.Omni’s IP addresses can be found on an individual connection’s page, accessed by navigating to Settings > Connections and clicking a connection.
