This specification implemented by all of the MongoDB drivers manages large files and their associated metadata as a group of small files, automatically reassembling them into the original large file when queried. It is used in various industries such as content management systems, healthcare, where large binary files like videos, images, PDFs are stored along with supporting information that fits naturally into JSON documents. GridFS simplifies application architecture, allows flexible document metadata expression, and leverages MongoDB's high availability and scalability infrastructure for binary data storage.
