在mongodb中一次插入2个集合中的大数据

// 引入MongoDB驱动程序
const MongoClient = require('mongodb').MongoClient;

// 定义要插入的数据
const collection1Data = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  // 更多文档...
];

const collection2Data = [
  { title: 'Post 1', content: 'Lorem ipsum dolor sit amet.' },
  { title: 'Post 2', content: 'Nulla facilisi. Aenean euismod.' },
  // 更多文档...
];

// 定义MongoDB连接字符串和选项
const url = 'mongodb://localhost:27017';
const options = { useNewUrlParser: true, useUnifiedTopology: true };

// 连接到MongoDB服务器
MongoClient.connect(url, options, (err, client) => {
  if (err) {
    console.error('Failed to connect to MongoDB:', err);
    return;
  }

  // 选择数据库和集合
  const db = client.db('mydatabase');
  const collection1 = db.collection('collection1');
  const collection2 = db.collection('collection2');

  // 执行批量插入操作
  collection1.insertMany(collection1Data, (err, result) => {
    if (err) {
      console.error('Failed to insert documents into collection1:', err);
      return;
    }
    console.log('Inserted', result.insertedCount, 'documents into collection1.');

    // 插入第二个集合的数据
    collection2.insertMany(collection2Data, (err, result) => {
      if (err) {
        console.error('Failed to insert documents into collection2:', err);
        return;
      }
      console.log('Inserted', result.insertedCount, 'documents into collection2.');

      // 关闭数据库连接
      client.close();
    });
  });
});
