Node.js axios upload large file using FormData, read all data to the memory, cause out of memory issue.

Describe the bug

Node.js axios upload large file using FormData, read all data to the memory, cause out of memory issue.

To Reproduce

  const formData = new FormData();
  formData.append('file', fs.createReadStream(path), { filepath: path, filename: basename(path) });
  formData.append('videoId', videoId);
  await axios.post(UPLOAD_MEDIA_URL, formData, {
    headers: {
      'Content-Type': `multipart/form-data; boundary=${formData.getBoundary()}`,
      'Authorization': `Bearer ${await token()}`,
    },
    maxBodyLength: Infinity,
    maxContentLength: Infinity,
  });

Expected behavior

Read file and upload by stream, without loading all data in the memory.

Environment

• Axios Version [0.21.1]
• Adapter [HTTP]
• Node.js Version [v14.16.0]
• OS: [Alpine in docker, OSX 10.15.6]
• Additional Library Versions [form-data@4.0.0]

Just give a clue for it, after I add the maxRedirects: 0 option, the upload will use much less memory than before. maxRedirects: 0 will switch the transport from http/https to follow-redirects, it seems follow-redirects use much more memory when uploading big file. Hope anyone can optimize this problem, thanks.
