In RisingWave, a database user is similar to a database user or role in Postgres, allowing a person or application to access a specific database or set of databases within a project. Also, you connect and log in to a project as one of its database users. Database users can be assigned specific permissions to control their database privileges. Currently, all database users have the superuser privilege. Future releases will introduce more granular permissions.

​
Create a database user

Choose one of the following to create a database user.
  • You can create a database user when connecting to a project.
  • You can click Create user in the Users tab on the project details page to create a new user.
  • You can run the CREATE USER command to create a new user after connecting to a project using the console or terminal. Ensure that you have logged in to the project with a user that has the CREATEUSER privilege. A super user has all privileges, including CREATEUSER.
