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)
