MongoDB 上的 GridFS 的最大大小是多少

GridFS在MongoDB中的最大大小是多少？

javascript
const MongoClient = require('mongodb').MongoClient;
const { GridFSBucket, ObjectId } = require('mongodb');
// MongoDB连接URL
const url = 'mongodb://localhost:27017';
// 连接到MongoDB数据库
MongoClient.connect(url, { useNewUrlParser: true }, (err, client) => {
  if (err) throw err;
  // 选择数据库和GridFS集合
  const db = client.db('mydatabase');
  const bucket = new GridFSBucket(db);
  // 存储文件
  const filePath = '/path/to/file.mp4';
  const uploadStream = bucket.openUploadStream('file.mp4');
  const fileStream = fs.createReadStream(filePath);
  fileStream.pipe(uploadStream)
    .on('error', (error) => {
      console.log('Error uploading file:', error);
      client.close();
    })
    .on('finish', () => {
      console.log('File uploaded successfully');
      client.close();
    });
  // 检索文件
  const fileId = new ObjectId('fileObjectId');
  const downloadStream = bucket.openDownloadStream(fileId);
  const writeStream = fs.createWriteStream('/path/to/save/file.mp4');
  downloadStream.pipe(writeStream)
    .on('error', (error) => {
      console.log('Error downloading file:', error);
      client.close();
    })
    .on('finish', () => {
      console.log('File downloaded successfully');
      client.close();
    });
});
