1. Gridfs IntroductionGridfs is a submodule of MONGO that uses GRIDFS to persist files based on MongoDB. and supports distributed applications (file distribution storage and reading). As a solution for storing binary data in MongoDB in a database, typically used to handle large files, there is a size limit for data (documents) stored in MongoDB's Bson format, up to 16M. However, in the actual system development, uploaded pictures or files may be large
