    Schema Management

    List Schema

    Get detail of all schema with property info

    // show node schemas
    nodeSchemas, _ := client.ListSchema(ultipa.DBType_DBNODE, nil)
    log.Println(nodeSchemas)
    
    // show edge schemas
    edgeSchemas, _ := client.ListSchema(ultipa.DBType_DBEDGE, nil)
    log.Println(edgeSchemas)
    

    Get Schema

    Get detail of one schema with property info

    //get node schema
    nodeSchema, _ := client.GetSchema("my_node_schema", ultipa.DBType_DBNODE, nil)
    log.Println(nodeSchema)
    
    //get edge schema
    edgeSchema, _ := client.GetSchema("my_edge_schema", ultipa.DBType_DBEDGE, nil)
    log.Println(edgeSchema)
    

    Create Schema

    // create schema without properties
    newSchema := &structs.Schema{
        Name: "new_node_schema",
        DBType: ultipa.DBType_DBNODE,
    }
    
    resp, _ := client.CreateSchema(newSchema, false, nil)  // the 2nd parameter 'false' means 'do not create properties'
    log.Println(resp.Status.Code)
    
    // create schema with properties
    newSchemaWithProperties := &structs.Schema{
        Name: "my_node_schema_prop",
        Desc: "A Schema with 2 properties",
        Properties: []*structs.Property{
            {
                Name: "username",
                Type: ultipa.PropertyType_STRING,
            },
            {
                Name: "password",
                Type: ultipa.PropertyType_STRING,
            },
        },
    }
    
    resp2, _ := client.CreateSchema(newSchemaWithProperties, true, nil)  // the 2nd parameter 'true' means 'create properties'
    log.Println(resp2)
    

    Create Schema If Not Exist

    Same function as 'Create Schema', return false if the schema already exists

    schema := structs.Schema{
        Name: "new_schema",
    }
    
    resp, _ := client.CreateSchemaIfNotExist(&schema, nil)
    log.Println(resp)
