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 v2.2.0 or later versions supports this function. To update the version, run this command.

docker-compose pull && docker-compose up

Prerequisites

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

  • The version of Studio is v2.2.0 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.

Create a graph space

To create a graph space on the Schema page, follow these steps:

  1. In the toolbar, click the Schema tab.
  2. On the Graph Space List page, click the + Create button.
  3. On the Create page, do these settings:

    a. Name: Specify a name to the new graph space. In this example, basketballplayer is used. The name must be distinct in the database.

    b. Optional Parameters: Set partition_num, replica_factor, charset, collate and vid type. In this example, these parameters are set to 10, 1, utf8, utf8_bin and FIXED_STRING(32) separately. For more information, see CREATE SPACE syntax.

    In the Equivalent to the following nGQL statement panel, you can see the statement equivalent to the preceding settings.

    CREATE SPACE basketballplayer (partition_num = 10, replica_factor = 1, charset = utf8, collate = utf8_bin, vid_type = FIXED_STRING(32))
    
  4. Confirm the settings and then click the + Create button. If the graph space is created successfully, you can see it on the graph space list.
