全部查询方法均支持使用可选配置参数（RequestConfig或InsertRequestConfig）来自定义向数据库发出的请求。您可使用该参数指定各种设置，如图集名称、超时时间和主机，根据自身需求定制请求。

RequestConfig

RequestConfig用来定义向数据库发送非插入请求时所需的配置。

import { ConnectionPool } from "@ultipa-graph/ultipa-node-sdk";
import { RequestType } from "@ultipa-graph/ultipa-node-sdk/dist/types";

let sdkUsage = async () => {
  //URI示例： hosts="mqj4zouys.us-east-1.cloud.ultipa.com:60010"
  let hosts = [
    "192.168.1.85:60061", 
    "192.168.1.86:60061", 
    "192.168.1.87:60061"
  ];
  let username = "***";
  let password = "***";
  let connPool = new ConnectionPool(hosts, username, password);

  let conn = await connPool.getActive();
  let isSuccess = await conn.test();
  console.log(isSuccess);
  
  // 指定图集amz为目标图集并使用集群的主节点 
  let requestConfig = <RequestType.RequestConfig>{
    graphSetName: "amz",
    useMaster: true,
  };
  
  let uqlResult = await conn.uql(`find().nodes([1]) as n return n.name`, requestConfig);
  console.log(uqlResult.data?.alias("n.name").asAttrs());  
  
};

sdkUsage().then(console.log).catch(console.log);

RequestConfig包含如下字段：

InsertRequestConfig

InsertRequestConfig 用来定义向数据库发送插入或删除数据请求时所需的配置。

import { ConnectionPool, ULTIPA } from "@ultipa-graph/ultipa-node-sdk";
import { RequestType } from "@ultipa-graph/ultipa-node-sdk/dist/types";

let sdkUsage = async () => {

  //URI示例： hosts="mqj4zouys.us-east-1.cloud.ultipa.com:60010"
  let hosts = [
    "192.168.1.85:60061", 
    "192.168.1.86:60061", 
    "192.168.1.87:60061"
  ];
  let username = "***";
  let password = "***";
  let connPool = new ConnectionPool(hosts, username, password);

  // 连接到default图集
  let conn = await connPool.getActive();
  let isSuccess = await conn.test();
  console.log(isSuccess);
  
  let node1 = new ULTIPA.Node();
  node1.schema = "card";
  node1.id = "ULTIPA8000000000000001";
  node1.values = {balance: Number(3235.2)};
  
  let node2 = new ULTIPA.Node();
  node2.schema = "client";
  node2.id = "ULTIPA800000000000000B";
  node2.values = {level: Number(7)};

  let nodes = [node1, node2];

  // 将上面的两个节点以覆盖模式插入到图集“test”中。
  let insertRequestConfig = <RequestType.InsertRequestConfig>{
    graphSetName: "test",
    insertType: ULTIPA.InsertType.INSERT_TYPE_OVERWRITE,
  };
  let uqlResult = await conn.insertNodesBatchAuto(nodes, insertRequestConfig);

  console.log(uqlResult.status.code);
  
};

sdkUsage().then(console.log).catch(console.log);

InsertRequestConfig包含如下字段：
