Mongoose在内存外插入许多堆

const data = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 35 },
  // 更多文档...
];

Model.insertMany(data)
  .then(() => {
    console.log('数据插入成功');
  })
  .catch((error) => {
    console.error('数据插入失败', error);
  });

const fs = require('fs');
const readline = require('readline');

const stream = fs.createReadStream('data.txt');
const rl = readline.createInterface({
  input: stream,
  crlfDelay: Infinity
});

rl.on('line', (line) => {
  // 处理每一行数据并插入数据库
  // ...
});

rl.on('close', () => {
  console.log('数据插入完成');
});

const data = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 35 },
  // 更多文档...
];

const promises = data.map((item) => Model.create(item));

Promise.all(promises)
  .then(() => {
    console.log('数据插入成功');
  })
  .catch((error) => {
    console.error('数据插入失败', error);
  });
