File size parameter

The export file can be cut in parts. It prevents from exporting too large and thus unprocessable files.
You can configure the size of the parts in the query tree through the max_file_size parameter. Its value must be given in octets.
From the latest example :

{
  "max_file_size" : 1000000,
  "linked_docs": [
    {
      "xobject_type_slug": "article_image_media",
      "document_type": "media",
      "link_type": "child",
      "linked_docs": []
    }
  ]
}
