如何理解图数据库的分布与分区

const tgraph = require('tgraph-sdk');

// 创建TGraph客户端
const client = new tgraph.Client({
  endpoint: 'your-endpoint',
  accessKeyId: 'your-access-key-id',
  accessKeySecret: 'your-access-key-secret'
});

// 创建图数据库
const graph = client.graph('your-graph-name');

// 添加节点
graph.addVertex({
  label: 'person',
  properties: {
    name: '张三',
    age: 18
  }
});

// 添加边
graph.addEdge({
  label: 'friend',
  outV: 'person-1',
  inV: 'person-2',
  properties: {
    since: '2022-01-01'
  }
});

// 查询节点
const result = graph.query('g.V().hasLabel("person").has("name", "张三")');
console.log(result);
