Operate graph spaces

When Studio is connected to Nebula Graph, you can create or delete a graph space. You can use the Console page or the Schema page to do these operations. This article only introduces how to use the Schema page to operate graph spaces in Nebula Graph.

Studio version

Studio of v1.2.1-beta or later versions supports this function. To update the version, run this command.

docker-compose pull && docker-compose up -d


To operate a graph space on the Schema page of Studio, you must do a check of these:

  • The version of Studio is v1.2.1-beta or later.
  • Studio is connected to Nebula Graph.
  • Your account has the authority of GOD. It means that:
    • If the authentication is enabled in Nebula Graph, you can use user and password to sign in to Studio.
    • If the authentication is disabled in Nebula Graph, you must use root and its password to sign in to Studio.
